REI Co-op Trailmade Pants vs Arc'teryx Gamma Pant - Women's

Editorial Team
Last modified at August 8, 2026
Choosing the right hiking pants often comes down to balancing comfort, durability, and the specific conditions you face on the trail. The REI Co-op Trailmade Pants stand out as a versatile, budget-friendly option that excels in comfort and weather resistance, making them ideal for day hikes and casual wear. In contrast, the Arc'teryx Gamma Pant is engineered for performance, featuring a robust soft-shell fabric that handles strenuous activity and variable weather with exceptional breathability. While both pants transition well from the trail to town, their design philosophies differ significantly: one focuses on a soft, protective fit for relaxed exploration, while the other delivers a technical, durable build for demanding outdoor pursuits.

4.8/ 5.0

4.4/ 5.0

Comfort is paramount for hiking pants, as it determines how long you can wear them without distraction during long treks or casual outings. A high comfort rating usually indicates soft fabrics, ergonomic cuts, and features like padded waistbands that prevent chafing. The REI Co-op Trailmade Pants dominate this category with a 4.8/5 rating, where buyers consistently praise the 'nice and comfortable' feel, 'amazing mobility,' and 'super soft' fabric that works well with or without underwear. While the Arc'teryx Gamma Pant also scores well at 4.4/5 with its 'right amount of stretch' and 'soft to the touch' feel, some users note the material can feel cold against the skin. For buyers prioritizing immediate, plush comfort and a relaxed fit, the REI option is the clear winner.

Durability

4.3/ 5.0

Durability measures a pant's ability to withstand abrasion from rocks, brush, and repeated washing over years of use. Strong durability often involves reinforced fabrics, tough hardware, and resistance to tearing or splitting seams. The Arc'teryx Gamma Pant takes the lead here with a 4.3/5 rating, utilizing a 42s 2.0 soft-shell fabric that buyers say can 'survive any kind of rock climbing' and resist scraping and scratching. The REI Co-op Trailmade Pants are solid at 4.1/5, praised for their 'thick and durable belt loops' and 'abrasion resistant' finish, but they have received some feedback regarding 'splitting seams' and general wear and tear. If your hiking style involves scrambling over granite or bushwhacking through dense brush, the Arc'teryx fabric offers a more resilient shield.

Fit

3.7/ 5.0

A good fit ensures freedom of movement without excess fabric getting caught on gear or feeling restrictive around the waist and thighs. It encompasses the cut, inseam options, and adjustability features like drawcords or belts. The REI Co-op Trailmade Pants earn a 4.1/5 for their 'slimmer fit' and 'incredible' high-waisted design, with many users loving the 'adjustable waist' and 'gusseted crotch' for movement. The Arc'teryx Gamma Pant scores slightly lower at 3.7/5; while they fit true to size with a 'trim and slim' cut, some buyers find the length 'significantly longer' or the calves 'a bit tight.' For those seeking a flattering, secure fit that accommodates various body shapes without feeling baggy, the REI pants provide a more consistent experience.

Breathability

3.9/ 5.0

4.3/ 5.0

Breathability is critical for regulating body temperature during intense exertion, preventing sweat buildup, and ensuring quick drying times. Pants with high breathability often feature lightweight, thin fabrics or mesh panels that allow air to circulate freely. The Arc'teryx Gamma Pant excels in this area with a 4.3/5 rating, described by users as 'highly breathable' and 'lightweight' with 'not much in the way of insulation,' making them ideal for hot days or high-output activities. The REI Co-op Trailmade Pants score a moderate 3.9/5; while some find them 'super light and breathable,' others note they are 'definitely warmer pants' that may require leg slits to cool off during strenuous hikes. If you tend to overheat easily or plan on fast-paced climbing, the Arc'teryx is the superior choice for airflow.

Weather Resistance

3.9/ 5.0

Weather resistance determines how well a pant protects against wind, light rain, and sun exposure, keeping you dry and warm in unpredictable conditions. This category relies heavily on DWR coatings, fabric density, and wind-blocking capabilities. The REI Co-op Trailmade Pants lead with a 4.4/5 rating, offering a 'durable water repellent finish' that effectively 'cuts wind and sheds light rain' while providing UPF 50+ sun protection. The Arc'teryx Gamma Pant, while offering 'impressive wind resistance' and a brushed fleece interior for colder weather, scores 3.9/5 because users note it is 'not necessarily waterproof' and can let moisture in during wet conditions. For hikers who need reliable protection against sudden showers and chilly winds without needing a shell layer, the REI pants offer better all-around weather defense.

Versatility

4.6/ 5.0

4.8/ 5.0

Versatility reflects a pant's ability to transition seamlessly from technical outdoor activities to casual social settings or travel. A highly versatile pant looks sharp in town while performing well on the trail, covering a wide range of seasons and activities. The Arc'teryx Gamma Pant wins this category with a 4.8/5, praised as an 'all-around pant' suitable for 'climbing, trail running, hiking, and warmer day skiing,' as well as 'wear around town' or 'go shopping.' The REI Co-op Trailmade Pants are also strong at 4.6/5, noted for their 'clean and versatile look' that works for 'casual hikes' or 'the office,' though some users feel they are better suited for 'cute casual kind of hikes' rather than technical terrain. For the ultimate 'one-pant' solution that handles everything from skiing to shopping, the Arc'teryx Gamma Pant is the most adaptable choice.
