The Claim: Colorado’s SeasonFive developed Atmos 1.0, a three-layer fabric that consists of a water-repellant outer face, a waterproof/breathable middle layer, and an inner layer meant to be worn against skin. They claim the fabric blocks wind, water, and UV rays while allowing heat vapor to escape so you can extend your season on the water while kayaking or stand up paddleboarding.
The Trial: I tested the women’s Barrier Series tank stand-up paddling last fall. The tank was my only layer during chillier SUP outings.
The Verdict: The Barrier Tank kept me warm and repelled water, but still breathed during a cardio workout. The design fits the female body well, plus it doesn’t irritate my skin, ride up, or move in the water. On the SUP, I was comfortable while dry: no rash, no hot spots, very breathable, and no restrictions on your movement. I incorporate yoga into my SUP paddles, which also means I’m prone to falling into the water. I paddled on after several spills and recoveries, staying just as comfortable and very warm in the damp tank. Only drawback? The tank felt bulky under a wetsuit. I’ll probably pick up the short sleeve version from SeasonFive for colder days or as a layering piece. That said, I’ll use the tank for SUP or cardio activities on the water where a simple top is enough. $70; seasonfive.com —Meghan Gruszynski
