Men's Syncrino Base LS Tee

The Rab Men's Syncrino Base LS Tee is built for cold mountain days when you need warmth, moisture management, and dependable comfort in the same layer. Its Syncrino™ 125 fabric blends merino wool with synthetic fibres, giving you the insulating, temperature-regulating feel of merino alongside the durability and fast-drying performance that matter in damp, changeable conditions.

In real use, this is the kind of baselayer that earns its place on long hill days, winter walking, and multi-day trips where you may be wearing it from first light to the last brew stop. The fabric is breathable, soft, and stretchy, with low-bulk seams that sit comfortably next to skin and layer easily under the rest of your system. Naturally anti-bacterial and odour-resistant, it’s a practical choice for trekking, climbing, mountaineering, and expedition use when carrying less and wearing gear longer is part of the day.
