With the weather warming, the blossoms blooming and trekking season rearing its head again, chances are, you’re looking for that perfect pair of hiking pants to comfortably explore the bucket list trails on your calendar. But what even makes a pair of hiking trousers worth the splurge, and where can you stand to save a little cash?
We pitted a pair of bestselling budget REI Trailmade Pants against performance brand Arc’teryx’s all-new Gamma Hybrid Pant to answer that very question. To get a full view of where each of the pants shined (and where they weren’t so great), I personally hiked up and down a handful of peaks in the Rocky Mountain foothills and took both pairs of trousers on a ten-day hiking tour of Japan’s fabled Nakasendo Way with Walk Japan. Over the course of a solid month of testing, these babies weathered rain storms, blustery springtime winds, hotel sink washes and miles upon miles of sweaty thighs.
Read on to find out if the REI Trailmade Pants or the Arc’teryx Gamma Hybrid Pant is the right addition to your hiking gear.
REI Co-op Trailmade Pants vs. Arc’teryx Gamma Hybrid Pant at a glance
REI Co-op Women's Trailmade Pants
Wallet-friendly and made with sustainable materials, these hiking pants offer key features like zippered side pockets, cinchable leg cuffs and rear stash pouches. They’re also incredibly quick-drying, should you face an unexpectedly high creek crossing.
Arc'teryx Women's Gamma Hybrid Pant
Stretchy, form-fitting and wonderfully weatherproof, Arc’teryx’s harness-compatible Gamma Hybrid Pant features a lay-flat elastic waistband and three different zippered pockets. Designed with the brand’s proprietary softshell fabric, the Gamma Hybrid Pant is great for windy, drizzly climates when you might not want to pack extra rain trousers.
REI Co-op Men's Trailmade Pants
With waist sizing from 28 to 50 inches, REI's affordable Trailmade Pants are made in three colors — though some discontinued shades may still be available for half off.
Arc'teryx Men's Gamma Pant
While they're not the same exact model as the women's Hybrid pant, these light-yet-durable pants boast the same proprietary softshell fabric.
Quick comparison
Fit and comfort
First and foremost, when I’m trying on a pair of hiking pants, I need to know that they’ll be comfortable and not sag at the waist when I’m knocking out a twelve-mile day on the trail. After the pandemic lockdowns, I’ve become enamored with stretchy waists and jogger styles, so I was pleasantly surprised to see that Arc’teryx just launched this soft-waisted “hybrid” style of its beloved Gamma Pant. Similarly, REI has designed its Trailmade Pants to feature a rear elastic band around the waist, even though the front presents more like a straightforward jean fit.
Fit and feel is the main category where these pairs of trousers differ. At first glance, the fabric feel of REI’s pants is a bit softer than Arc’teryx’s Gamma, but when you look under the hood for a moment, you’ll see why. Arc’teryx has designed its Gamma Hybrid Pant with softshell material, meaning that it will easily ward off strong wind gusts and shed mild precipitation. On long days hiking up and down Japan’s volcanic foothills, I noticed that the stretch of these trousers kept them comfy on full ten-mile days, and the waistband didn’t stretch out or sag down throughout the day. The overall fit of the Gamma is true to size and flattering, especially with that fantastic lay-flat waistband.
REI’s Trailmade, on the other hand, is designed like a more traditional, quick-dry hiking pant, like Prana’s beloved Halle. The body fit is looser, compared to the snugger Gamma, and it features articulated knees, as well as cinchable ankle cuffs to keep out insects and debris. The only downside? I did notice this pair of pants sag down a bit on my longer day hikes, likely due to the waist stretching out with time. Thankfully, REI included an internal drawcord to help keep them up, even on my gnarliest days. The Trailmade runs a smidge large, too, so if you’re between sizes, consider sizing down, as I had to.
TL;DR: REI’s Trailmade Pants offer a looser fit and softer fabric, but lack the lay-flat waist and softshell protection of the pricier Arc’teryx Gamma Hybrid Pant.
Pockets
Here’s another area where I’m a stickler when it comes to hiking pants: pockets. I don’t care how comfortable a pair of trousers is; if they don’t include at least one zippered pocket for my smartphone, I’m not taking them on the trail.
I’m sure you can imagine that I was pleased as punch to find that both the Trailmade and the Gamma Hybrid included well-sized, slightly stretchy zippered thigh pockets that were the ideal size for a phone or a small trail snack. Though the more expensive Gamma only offers three pockets, all of them are zippered, making these pants a better choice for climbers or mountaineers who need the extra protection for easy-access small items. On my hiking trip with Walk Japan, I stashed a map, lip balm, phone and a pack of gum into these pockets with zero-chafing.
The Trailmade is designed with a whopping five pockets, but they’re much more like the open fabric pouches you’d find on a pair of street-ready jeans, minus one excellent zippered leg pocket. This is great if you like to quickly grab small necessities without fidgeting with a zipper, but personally, it’s not my style. On my Rocky Mountain day hikes, I tend to only use the thigh pocket, then store my other valuables into a lightweight daypack.
TL;DR: It’s a draw. The Gamma Hybrid offers fewer pockets than its budget counterpoint, but all three are zippered. REI’s Trailmade serves its wearers an impressive five pockets, but only one has that coveted security zipper.
Weatherproofing
As I briefly mentioned before, Arc’teryx’s Gamma Hybrid Pant is a bit thicker and heavier than REI’s Trailmade, because it’s designed as a softshell trouser, able to fend off high winds and moderate rain while staying breathable for high-intensity pursuits.
The wallet-friendly Trailmade Pants come coated in a durable water repellent (DWR) to shed mild weather, but on my rainiest days in Japan, they soaked through in under an hour. However, they are rated at UPF 50+ when it comes to sun protection, making them a great lightweight pick for summer hiking.
In my month of testing, both pairs of pants were fabulously quick-drying, even after rough and tumble hotel sink washes, when I really needed my pants to dry out overnight in my room. Both trousers rose to the occasion in Japan, fully drying out while I slept, which makes them double as awesome travel pants, especially when space in your carry-on is sparse.
TL;DR: Though the Trailmade is coated with a DWR, the Gamma Hybrid is more water- and wind-proof. That being said, both were incredibly quick to dry in our tests.
Bottom line
Both the REI Trailmade Pants and the Arc’teryx Gamma Hybrid Pant are stretchy, quick-drying and offer a zippered thigh pocket. Where they differ, however, is in Arc’teryx’s use of high-tech softshell fabric, which is more wind- and weather-resistant than REI’s DWR-coated nylon.
If you’re an avid climber or mountaineer, the security pockets and harness-compatible, lay-flat waistband of the Gamma Hybrid Pant are likely to be the tantalizing features that make this $180 splurge worth it. For most of us who simply want a comfortable, quick-drying hiking pant that’s got plenty of pockets and won’t break the bank? Go with the Trailmade. You can’t beat REI’s second-to-none product guarantee, either.
