REI Co-op Swiftland TT review: a trail running vest that takes on the big brands

The REI Co-op Swiftland TT hydration vest offers a tailored fit, smart storage, and included flasks at $130. Here's how it compares to premium trail running vests.

REI Co-op Swiftland TT review

Trail running vests have become a crowded space with Salomon, Nathan, Osprey, and Ultimate Direction setting the standard for years. A vest at $130 from REI's own brand might not be the first thing you reach for when researching your next pack but honestly, it needs to be on your radar.

The REI Co-op Swiftland TT Hydration Vest is one of the more quietly impressive pieces of trail running gear I've reviewed recently.

TT stands for Technical Terrain, and the design reflects that: this is a vest built for trail runners and hikers who need reliable hydration, smart storage, and a fit that stays comfortable over long, demanding days outside.

What surprised me most is how well it competes with vests that cost significantly more.

Features I love

The fit is genuinely tailored, not just adjustable

Most vests offer some adjustability but the Swiftland TT goes further than most.

The hook-and-loop velcro side straps let you dial in the fit precisely around your torso without over-tightening the front panels, and the soft stretch fabric molds to the body in a way that feels considered rather than generic.

The result is a vest that sits close and moves with you rather than shifting around.

On longer efforts that makes a significant difference with less chafing, less fatigue from fighting the pack, and a generally more comfortable day on trail.

The quick-release chest toggles are a useful addition too, allowing you to loosen things up quickly on steep climbs when deeper breathing matters most.

The front phone pocket is one of the best I've used

This sounds like a small thing, but it's one of the most common frustrations with running vests: a phone pocket that bounces, digs in, or simply doesn't fit a modern-sized phone securely.

The Swiftland TT gets this right.

My phone stays in place, doesn't create pressure against the chest, and doesn't bounce too noticeably even at higher effort levels. For anyone who runs with their phone for navigation, safety, or photography, this alone makes the vest stand out from a crowded field.

Storage is well thought out for real trail use

The vest carries 7L of gear and includes two 500ml HydraPak SoftFlasks up front, which arrive ready to use straight out of the box.

Beyond the front flasks and phone pocket, there are two zippered chest pockets for snacks and small items, stretchy dump pockets for quick-access essentials, and a main rear compartment that fits a packable jacket or extra layers comfortably.

It's also reservoir compatible if you prefer a bladder setup for longer days, though that's sold separately.

The pole attachments and PLB pocket are serious outdoor additions

A lot of trail running vests at this price skip the details that matter on bigger mountain days. The Swiftland TT includes dedicated pole attachments, which is a practical must if you use trail running poles on technical climbs or long outings.

The shoulder pockets are also sized and designed to carry a personal locator beacon like a Garmin inReach Mini, which is a thoughtful touch for anyone running in remote locations without cell coverage.

These aren't features you'd necessarily expect at $130, and their inclusion says something about what REI was going for with this design.

The value case against premium competitors is strong

The Salomon Active Skin 4 and Salomon Adv Skin 5 are both excellent vests and are the obvious comparisons at this level. Both cost more.

The Swiftland TT competes on comfort, storage layout, and fit adjustability in a way that makes the price gap feel meaningful when you're deciding between them.

Best Hydration Packs For Running In 2026 [Tried & Tested]
Whether you’re running 5k, half marathons, marathons or ultras, there’s a running hydration vest for you in this running vests roundup.

If you're an REI member, it's also worth knowing that dividend rewards can offset the cost further; they also happen to have their Anniversary sale on right now (you can pick this vest up for only $104.89 $139.95 which is 25% off - bargain!) Our guide to spending REI member rewards on trail gear has more on how to make the most of that.

What could be improved

The rear compartment is a little hard to access while running. If you need to grab a jacket or larger item from the back mid-run without stopping, it's awkward enough that most people won't bother.

This is a common challenge with running vest design at this capacity, but it's worth knowing going in if quick access to rear-stored gear is important to your use case.

Breathability through the back panel is adequate but not exceptional. On very hot days or high-output efforts, it can feel warm. The vest performs better in cooler conditions or at moderate intensity, which covers most trail running and hiking scenarios well enough.

My verdict

The REI Co-op Swiftland TT is a well-made, genuinely comfortable trail running vest that holds up well against more expensive options. The adjustable fit, bounce-free phone pocket, included flasks, pole attachments, and smart pocket layout make it easy to recommend for trail runners and hikers who want a capable, practical pack without paying premium brand prices.

At $130 it represents strong value in a category where spending $150 to $200 is easy to do. If you're building out your trail and hiking kit and want a vest that handles long days comfortably, this belongs on your shortlist.
