The short version: inseam decides more than fabric
Both pants zip off at the knee and both use stretch synthetic fabric, so the practical difference is how well each one is likely to fit you on the first order. Moosehill's M015 page lists two inseams, 30 and 32 inches, and letter sizes from S to 7XL. We found no size chart with waist or hip measurements on the product page on 29 October 2026. [1]
REI's Sahara Stretch Convertible page, model 242911, listed a 31-inch regular and a 34-inch tall inseam when we read it on 20 September 2026. REI's site refused our automated request on 29 October 2026, so we could not recheck it; confirm the model number, fabric and inseams on the live page before you order, because product versions and fabrics can change between seasons. [2]
This is a comparison of published specifications. We have not worn, washed or field-tested either pair.

Worked example: matching an inseam you already know
This example is invented. Measure the inseam of the pants you hike in most comfortably, from crotch seam to hem. Say it is 31 inches. The REI regular matches it exactly; the Moosehill options are one inch shorter or one inch longer. If you usually wear boots and like a slightly longer hem, the 32 may be fine; if you hate fabric bunching at the ankle, the 30 may be. Either way you are guessing by an inch, while the REI regular removes that guess. [1][2]
Change the measurement to 33 or 34 inches and the answer flips toward REI's 34-inch tall, because the longest M015 inseam listed is 32. Change it to 30 inches and the M015 30 is the only exact match of the two. If you need a large waist, M015's letter range reaches 7XL, but with no numeric chart on the page you should ask the store for the waist measurement of your size before ordering. [1][2]
Who should pick which, and who should skip both
- Start with REI Sahara Stretch if your known inseam is 31 or 34 inches and you can confirm the live page still lists the same model. [2]
- Start with Moosehill M015 if you need a 30- or 32-inch inseam, want hook-and-loop ankle tabs, or need a letter size above what your other options stock. [1]
- Skip both if you never take trouser legs off on a trip. A zip that sits at your knee is a seam you sit on all day for a feature you do not use.
- Skip both if you actually need rain protection. A water-repellent finish beads water off the face fabric; Arc'teryx describes it as a surface coating that can wet out from dirt, sweat, sunscreen and bug spray. Buy rain pants for sustained rain. [3]
- Skip a last-minute order if the return window or the delivery time leaves no room to exchange before you leave. M015's product details list standard shipping of 8 to 15 days, while the site banner advertises US delivery in 2 to 5 days. [1]
The cost of guessing wrong
Compare what a failed fit costs, not just the sticker price. In an invented comparison, Pair A costs $57 delivered with a hypothetical $10 return cost, while Pair B costs $70 delivered with free returns. Keeping B costs $13 more; sending A back costs $10. If you are confident about the fit, A is cheaper; if you are not, the gap almost disappears and the faster, clearer return wins.
Moosehill's own pages give two different return windows, 30 days on the product page and 50 days in the site banner. Treat the shorter one as the planning number until the store confirms the longer one in writing. [1]
Before you order: a five-minute checklist
- Write down the inseam and waist of the pants that fit you best.
- Open both live product pages and record price, fabric, inseams and the date.
- For M015, ask for the waist measurement of your letter size if no chart appears. [1]
- For REI, confirm the model number is 242911 and the inseams still read 31 regular and 34 tall. [2]
- Write down the return window you are relying on and how you will send the pants back.
- Do the indoor fit check on arrival: sit, squat and step up onto a chair with the tags on, and check where the leg zip sits on your knee.
What this comparison cannot tell you
We have no drying-time measurements, abrasion observations, washed-versus-new fit checks or trail hours for either pair, so we do not name a performance winner. If water repellency matters to you, read the care guide on this site: a repellent finish can usually be revived with a clean wash and heat, and it is not the same as waterproof construction. [3]
Questions before you decide
Which pair is more water resistant?
Neither page we read provides a test. Moosehill describes M015 as water-repellent and quick-dry for dew or sudden rain, which is a surface finish claim, not rain protection. Arc'teryx's care page explains that such finishes stop beading when dirt, sweat or sunscreen contaminate them.
Is the Moosehill return window 30 or 50 days?
On 29 October 2026 the M015 product page said 30-Day Fit Guarantee and the site banner said 50-Day Returns. Plan around 30 days unless the store confirms 50 in writing for your order.
Does Moosehill publish a waist chart for M015?
We found letter sizes S to 7XL and two inseams, 30 and 32 inches, but no numeric waist or hip measurements on the product page on 29 October 2026. Ask the store before ordering if you are between sizes.
