Mountain Hardwear Launches 'Sun Drift Cooling Shirt' to Make Summer Trails More Comfortable

Mountain Hardwear (Columbia Sportswear Japan Co., Ltd., 7F, 6-27-30 Shinjuku, Shinjuku-ku, Representative: Massimo Lazzari), a mountain sports brand born in California, USA in 1993, will launch the "Sun Drift Cooling Shirt" series developed to help people comfortably enjoy summer trails.

To combat the intense summer heat, the "Sun Drift Cooling Shirt" series adopts the cooling technology "HEIQ COOL" developed by HeiQ, a Swiss manufacturer of high-performance materials. Its dual function of contact cooling and evaporative cooling provides a continuous cooling effect from the moment it is worn through the duration of activity. It also features "HEIQ MINT," a plant-based odor control function, suppressing sweat odors even during long treks. With a wide variety of colors available for both men and women, this shirt collection expands the joy of summer mountaineering.

Equipped with great features for summer mountains such as cooling, breathability, odor resistance, and UV protection, this series proposes freer and more comfortable summer hikes.

Technology & details

・HEIQ COOL

Dual cooling technology via contact cooling and evaporative cooling

A cooling technology developed by the Swiss high-performance material manufacturer HeiQ. The contact cooling function, which feels cold to the touch, delays the rise in body temperature, and once sweating begins, the evaporative cooling function releases sweat and heat together to deliver a sustained cooling effect.

・HEIQ MINT

Renewable plant-based odor control technology

HEIQ MINT, derived from mint oil extracted from plants, is bound to the fabric. It maintains high stability, renewing its performance with every wash even after repeated wear, controlling sweat and textile-specific odors.
