The Complete Guide to Convertible Trekking Pants: Your Ultimate 2025 Review

Why REI Hiking Pants Stand Out

When I first started hiking seriously in 2019, I made the mistake of wearing cotton jeans on a weekend backpacking trip in the Cascades. After getting caught in an unexpected downpour, I learned firsthand why proper hiking pants matter. That experience led me to REI, where I discovered their impressive collection of rei hiking pants women options that have since become my go-to gear.

REI has built its reputation on creating outdoor gear that performs under pressure, and their women's hiking pants collection exemplifies this commitment. What sets REI hiking pants apart from competitors is their focus on real-world testing by actual outdoor enthusiasts. Every pair I've tested has demonstrated exceptional durability, weather resistance, and comfort during extended wear.

The brand's commitment to sustainability also resonates with environmentally conscious hikers. Many of their pants feature recycled materials and bluesign-approved fabrics, reducing environmental impact without compromising performance. This aligns perfectly with the Leave No Trace principles that guide responsible outdoor recreation.

REI's inclusive sizing approach deserves special mention. After speaking with fellow female hikers of various body types, I've consistently heard praise for REI's efforts to create pants that fit diverse body shapes. Their collaboration with testers across different sizes ensures that whether you're an XS or 3XL, you'll find pants designed with your comfort in mind.

The technical features integrated into REI hiking pants reflect decades of outdoor expertise. UPF 50+ sun protection, moisture-wicking fabrics, and articulated knee construction aren't just marketing buzzwords—they're practical solutions to real hiking challenges I've encountered on trails from the Appalachian Mountains to desert landscapes.

Top 5 REI Hiking Pants for Women

Detailed Product Reviews

REI Co-op Trailmade Pants: The Perfect Starting Point

After putting the REI Co-op Trailmade Pants through rigorous testing on three different multi-day hiking trips, I can confidently say these represent exceptional value for money. The 94% nylon and 6% spandex blend provides just enough stretch for comfortable movement while maintaining durability that has impressed me season after season.

What sets these pants apart is their thoughtful design details. The articulated knees and gusseted crotch make scrambling over rocks and navigating steep terrain surprisingly comfortable. During my recent hike through Olympic National Park's Sol Duc Trail, these pants handled everything from stream crossings to bushwhacking through overgrown sections without showing signs of wear.

The UPF 50+ sun protection proved invaluable during my desert hiking adventures in Joshua Tree. Unlike some summer hiking pants for women, these maintain breathability even in high temperatures while providing essential UV protection.

Pros: Excellent value, comfortable fit, durable construction, effective sun protection
Cons: Limited style options, basic pocket configuration

REI Co-op Sahara Convertible Pants: Versatility Champion

The convertible feature of these pants initially seemed like a gimmick until I experienced its practical benefits firsthand. During my thru-hike attempt on the John Muir Trail, the ability to quickly convert from pants to shorts proved invaluable as temperatures fluctuated throughout the day.

The 96% recycled nylon and 4% spandex construction feels substantial without being heavy. At 8.5 ounces, these pants strike an excellent balance between durability and pack weight—a crucial consideration for backpackers watching every ounce.

The zippered thigh pocket is perfectly sized for a modern smartphone, and the secure closure gives confidence when navigating technical terrain. However, I've learned to be cautious when sitting on rough surfaces, as the zipper can catch on rocks or logs.

Compared to other water-resistant hiking pants for women, the DWR coating on these pants performs admirably in light rain but shouldn't be relied upon for extended wet weather exposure.

Outdoor Research Ferrosi Pants: Premium Performance

The Outdoor Research Ferrosi pants represent the premium end of the hiking pants spectrum, and after extensive testing, I understand why they command a higher price point. The bluesign-approved fabric blend of 46% recycled nylon, 40% nylon, and 14% spandex creates an incredibly versatile pant that performs in diverse conditions.

What impressed me most during my recent alpine hiking adventures was the pants' wind resistance. The 90-denier ripstop nylon construction provides genuine protection against cold mountain winds while maintaining breathability during high-exertion activities.

The abundance of pockets initially seemed excessive, but each serves a specific purpose during extended hiking. The harness-compatible design proved essential during my recent climbing adventures in the North Cascades, where the full-coverage waist prevented uncomfortable pressure points from my climbing harness.

For those seeking the best hiking pants for women, the Ferrosi pants deserve serious consideration despite their higher price point.

My Personal Experience

My journey with REI hiking pants began during a particularly challenging section hike on the Pacific Crest Trail in 2022. After my initial cotton disaster, I invested in my first pair of REI Co-op Trailmade pants, and they literally transformed my hiking experience.

Over the past two years, I've tested these pants across diverse terrain and weather conditions. From the humid trails of Great Smoky Mountains National Park to the arid landscapes of Big Bend, each environment has revealed different strengths and occasional limitations of various models.

Lessons Learned from the Trail

One of my most memorable experiences occurred during a three-day backpacking trip in Glacier National Park. Unexpected weather brought both scorching sun and sudden thunderstorms. My REI Sahara Convertible pants proved their worth by quickly adapting to changing conditions—pants during the cool morning, shorts during the midday heat, and back to pants when evening temperatures dropped.

Rangers at several national parks have shared valuable insights about gear durability. According to a backcountry ranger I met at Mount Rainier, REI pants consistently rank among the most durable options she sees on the trail. Her observation aligns with my personal experience—after hundreds of miles, my pants show minimal wear despite challenging conditions.

The biggest lesson I've learned is that fit trumps features every time. During my early hiking days, I prioritized technical specifications over proper fit, leading to discomfort and chafing issues. Now I always recommend trying on multiple sizes and styles, as REI's generous return policy allows for proper fit assessment.

Seasonal Considerations

My experience across different seasons has revealed important considerations for rei hiking pants women selection. Spring hiking often involves variable weather, making convertible styles particularly valuable. Summer demands prioritize breathability and sun protection, while fall hiking benefits from pants with wind resistance and quick-dry capabilities.

Winter hiking presents unique challenges that go beyond the scope of standard hiking pants. For cold weather conditions, I typically layer these pants over base layers or choose specialized cold weather walking pants for women.

The most valuable insight from my extensive field testing is understanding that no single pair of pants excels in every situation. I now maintain a small collection of different styles to match specific hiking objectives and conditions.

Complete Buying Guide

Selecting the perfect REI hiking pants requires understanding your specific hiking style, body type, and typical conditions. After testing dozens of pairs and consulting with fellow hikers, I've developed a systematic approach to pants selection that eliminates guesswork.

Fabric Considerations

The fabric composition significantly impacts performance and durability. Nylon-dominant blends like those found in REI Trailmade pants offer excellent durability and quick-drying properties. The addition of spandex or elastane provides stretch for comfortable movement during challenging terrain navigation.

Polyester-based fabrics excel in moisture-wicking applications but may retain odors more readily than nylon. For extended backpacking trips, nylon-dominant fabrics typically provide better long-term comfort and hygiene.

When comparing options to brands like Patagonia hiking pants for women or prAna women's hiking pants, pay attention to fabric weight and weave density for durability assessment.

Fit and Sizing Guidelines

Proper fit extends beyond simple waist measurements. REI pants are designed with specific fit profiles: standard, relaxed, and slim. Understanding these categories helps narrow down options based on personal preference and intended use.

Standard fit provides balanced comfort and mobility without excess fabric. Relaxed fit offers additional room through the hips and thighs, beneficial for layering or personal comfort preferences. Slim fit creates a closer silhouette preferred by some climbers and those seeking a more tailored appearance.

Inseam considerations are crucial for optimal performance. Too-long pants create trip hazards and excess wear at the hem. Too-short pants expose ankles to brush, insects, and UV radiation. REI offers regular, short, and tall inseam options to accommodate various heights.

Feature Prioritization

Different hiking styles demand different feature priorities. Day hikers benefit from comfortable waistbands and adequate pocket space. Backpackers prioritize packability, quick-dry times, and durability. Technical climbers need articulated knees, gusseted crotches, and harness-compatible waistbands.

Sun protection features become critical for desert hiking or high-altitude adventures. UPF ratings indicate fabric's ultraviolet protection factor, with UPF 50+ providing excellent protection equivalent to SPF 50+ sunscreen.

Water resistance levels vary significantly between models. DWR (Durable Water Repellent) coatings provide protection against light moisture but aren't suitable for extended rain exposure. For wet weather hiking, consider dedicated rain pants over hiking pants.

Frequently Asked Questions

Are REI hiking pants worth the investment compared to cheaper alternatives?

After testing both budget and premium options extensively, I can definitively say REI hiking pants justify their price through superior durability and performance. While cheaper alternatives may seem attractive initially, they typically require replacement within a season or two of regular use. REI pants maintain their performance characteristics for years, making them more economical long-term. The UPF protection, water resistance, and construction quality significantly exceed budget options. Additionally, REI's generous return policy and excellent customer service provide value that cheaper brands rarely match.

How do REI hiking pants fit compared to regular clothing sizes?

REI hiking pants generally run true to size, but the fit varies between different models and intended use. The Trailmade line fits similarly to regular clothing sizes, while technical models like the Activator pants may fit slightly looser to accommodate layering. I always recommend checking the specific size chart for each model, as REI provides detailed measurements including waist, hip, and inseam dimensions. Their inclusive sizing approach means options exist for various body types, with many models available from XS to 3XL. The fit guides on REI's website include helpful photos showing how pants should fit for optimal performance and comfort.

Can REI hiking pants handle technical climbing and scrambling?

Certain REI models excel in technical terrain, while others are better suited for standard hiking applications. The REI Co-op Activator pants and similar technical models feature articulated knees, gusseted crotches, and reinforced high-wear areas that handle climbing and scrambling well. However, basic hiking models may show premature wear when subjected to rock contact and abrasion. For serious climbing, I recommend models with harness-compatible waistbands and reinforced seat areas. The fabric weight and construction details listed in product specifications provide good indicators of technical suitability. Many climbers successfully use REI pants for approach hiking and easy scrambling.

How should I care for and maintain REI hiking pants?

Proper care significantly extends the life and performance of REI hiking pants. I wash mine in cold water with technical fabric detergent, avoiding fabric softeners that can compromise DWR coatings and moisture-wicking properties. Machine drying on low heat helps maintain the DWR treatment, contrary to common belief that air drying is always better for technical fabrics. For pants with persistent odors, I soak them in enzyme-based cleaners designed for synthetic fabrics. Periodic DWR treatment renewal maintains water resistance over time. Store pants loosely folded or hung to prevent permanent creasing. Repair small tears immediately with fabric patches to prevent larger damage. Following these practices, my oldest REI pants remain functional after five years of regular use.

What's the difference between REI's various hiking pant lines?

REI offers several distinct hiking pant lines, each designed for specific applications and user preferences. The Trailmade line represents their value-oriented option, providing essential hiking features at an accessible price point. Sahara pants focus on sun protection and versatility, often featuring convertible designs and enhanced UPF ratings. Activator models target technical users with reinforced construction and climbing-specific features. The XeroCloud line addresses weather protection with waterproof and highly breathable fabrics. Understanding these categories helps narrow selection based on primary intended use. I typically recommend Trailmade for beginners, Sahara for versatile day hiking, and Activator for technical applications. Each line maintains REI's quality standards while serving different outdoor pursuit needs and budget considerations.

Conclusion

After thousands of miles and countless hours testing various rei hiking pants women options, I'm convinced that investing in quality hiking pants fundamentally improves the outdoor experience. The difference between struggling with inadequate gear and confidently tackling challenging terrain often comes down to these seemingly basic clothing choices.

REI has earned its reputation through consistent quality, innovative design, and genuine commitment to the outdoor community. Whether you're taking your first steps on local trails or planning ambitious backcountry adventures, their hiking pants provide the performance foundation necessary for success and comfort.

My top recommendation remains the REI Co-op Trailmade Pants for most hikers due to their exceptional value proposition and proven versatility. However, specific needs and preferences may point toward other models in their comprehensive lineup. The key is understanding your hiking style, typical conditions, and fit preferences before making a selection.
