REI Co

All runners know the importance of choosing durable, reliable gear — but that goes double for trail runners. When you’re completely surrounded by nature, you need clothing and accessories that not only stand up to your adventures but support them. That's where REI Co-op sets itself apart, and on June 1, the brand will release a new running shoe specifically for trail runners: the Swiftland MT.

REI Co-op isn't your average retailer, and that's because (as per its name) it's a member-owned co-operative rather than a company with shareholders. As a result, its success is measured through positive impact, which includes fighting to protect the environment, investing in hundreds of nonprofit partners and distributing rewards to its millions of Co-op members.

When developing the Swiftland MT, sustainability was at the core of its product development. All major components of the sneaker are made using recycled or bio-based materials — but that doesn't mean this shoe compromises on performance. The Swiftland MT will be available for purchase starting June 1, and REI Co-op members get first dibs through June 30.

Available in both men's and women's sizes, the Swiftland MT is REI's foundational trail running shoe. Using recycled materials like a rubber TerraGrip™ Run outsole, FirmaKnit™ Run upper and a nylon rockguard, it's designed to offer durability, support and confidence when running over all kinds of terrain. In addition to recycled materials, it also features a Bloom Algae sock liner and TerraLoft™ Run midsole for comfort, cushion and durability.

This shoe joins 40 other products in the REI Co-op Swiftland collection, an entire line of clothing and accessories for runners. For comfort and protection from head to toe, check out these other top-selling styles from Swiftland.

This running T-shirt has earned an overall 4.7-star rating from reviewers, who have called it so "comfortable and lightweight," they feel "almost shirtless." Also available in women's, it's made from microventilated SwiftTex, which is airy and sweat-wicking enough to keep you cool on the hottest of trails. Other thoughtful features include flat seams to prevent chafing, reflective trim for safety and underarm gussets for optimal mobility. Get it in five colors and several sizes, including tall options.

One of the collection's top-selling items, these running shorts keep you cool, comfortable and safe on your adventures. Their woven nylon-spandex material wicks sweat and stretches four ways, while their built-in brief-style liner offers coverage without restriction. They even have four separate pockets and a drawcord waistband for a personalized fit. No wonder reviewers have called them their "favorite shorts ever." You can get them in men's sizes too.

Wear your hydration with this adjustable vest, which was designed and tested for trail running. While it can hold up to 1.5 liters in its reservoir and has a high-flow bite valve that self-seals after every sip, it's still breathable, stretchy and designed to fit snugly during movement. It also has ample pockets for your running gear as well as reflective tabs for safety — plus, it's made with recycled materials to keep waste out of landfills. Check out the women's version here.
