Snow Peak launches first cooling wear line for Japan's heatwave summers

Snow Peak has taken its first serious swing at cooling apparel with a four-piece line that reads less like a seasonal drop than a working answer to summer heat. The Japanese outdoor brand’s Cooling System Wear collection launched in Japan on May 22, with two new vests at the center: the Peltier Cooling Device Vest and the Water Cooling Device Vest. Both are cut in Taslan nylon, giving the line the rugged, matte finish Snow Peak fans expect, but with engineering that aims squarely at heat management rather than styling exercise.

The Peltier vest is the flashier piece and the pricier one, set at 99,000 yen in black and offered in sizes 1 and 2. Snow Peak built it around six Peltier units and two fan units operating together, pairing contact cooling with fan-driven evaporative cooling. The Water Cooling Device Vest, by contrast, is the quieter utilitarian option at 57,200 yen in black, one size. It uses a rear tank, pump and internal tubing to move cold water through the vest, and Snow Peak designed it so ice or refrigerant packs can be added when the temperature turns punishing. A removable internal cooling sheet also lets the water-cooling vest work as a lighter multi-purpose layer when the system is not needed.

That split is smart. The Peltier vest feels like the more specialized tool, built for someone who wants a more aggressive cooling system and is willing to pay for it. The water-circulation vest looks more adaptable, the kind of piece that could move from commuting to campsite to a hot industrial or service environment without feeling overbuilt. Together, they push workwear toward something closer to wearable climate control, which is where the conversation is headed as Japanese summers grow harsher.

Snow Peak framed the launch around that reality. The company said recent summers have brought earlier heat spikes and frequent days above 35C, and Japan’s weather agency described the 2025 summer as record-setting, with average temperatures from June through August 2.36C above normal. The collection also included two previously released items, the Peak Shade evaporative poncho and a stainless steel cooling pack, giving the line a broader toolkit for heat relief rather than a single hero product.

For Snow Peak, the move fits its wider apparel strategy: functional gear that supports comfort, outdoor freedom and a more restored relationship with nature. Headquartered in Sanjo, Niigata, the company is led by chairman Tohru Yamai and president Takafumi Minaguchi under its buddy management structure. But the real story here is not corporate choreography. It is Snow Peak’s attempt to make cooling technology feel as considered, durable and wearable as the brand’s best-known outdoor gear, and that makes this one of the more meaningful technical launches in workwear this year.
