BTMK LONG TEE coolest pocket「-5℃」srn99

BTMK's “-5°C” Long Sleeve T-Shirt is crafted using the latest antibacterial and contact cooling technology, combined with renewable cotton and advanced Japanese spinning techniques.

The cutting-edge cooling fiber technology used in this item is composed of premium SUPIMA® cotton and cooling molecules derived from plant-based corn alcohol. Through phase change, the fabric absorbs heat and regulates its temperature. When the fabric touches your skin, you’ll immediately feel a noticeable coolness—lowering the perceived temperature by up to -5°C—delivering the “stress-free” comfort that BTMK stands for.

This item also features UV protection, blocking 99% of harmful UV rays, eliminating the need to layer up for sun protection.

With a simple design that pairs well with various styles, the chest pocket adds a subtle accent, making this a versatile and long-lasting wardrobe staple.
