Salewa Cristallo Warm Alpine Man's T-shirt Dark Denim

A men’s warm, hybrid merino wool baselayer for high-intensity alpine mountaineering in cold-weather conditions.

The Cristallo is winter, short-sleeved baselayer designed for wicking warmth, next-to-skin comfort and natural anti-odour performance for active use. 
Alpine Merino Responsive fabric is a hybrid composition fabric made of 78% merino wool and 22% polyamide. It transports moisture away from the body and dries quick. The synthetic fibres are enhanced with our proprietary Responsive technology. Responsive is based on a special blend of natural thermoreactive minerals that recycles far-infrared (FIR) energy from your body, helping you to perform better, recover faster and stay warmer for longer. These benefits last for the life of the fabric as Responsive is part of the fabric yarn and does not wash out. Alpine Merino Responsive is also certified as bluesign® approved.
The Cristallo is made using a special knitting process that spins a superfine merino wool yarn around a nylon core. This process makes the resulting fibre not only stronger and fleecier, but also 30% lighter than a comparable baselayer. The high polyamide content further improves its durability and mechanical stretch properties. In a slim fit with a crew neck, gusseted sleeve design for greater freedom of movement and no irritating seams.
