Brynje Wool Thermo Shirt

A superfine merino mesh base layer that insulates at rest and wicks on the move.

The Brynje Wool Thermo Shirt is a unisex slim-fit base layer built from 80% superfine merino wool reinforced with polyamide. The open mesh construction minimises skin contact, allowing air to circulate while transporting moisture and excess heat away from the body. During low activity, trapped air forms an insulating layer close to the skin — making it suitable for medium to low-intensity use in cool conditions year-round.

Features

• Mesh construction wicks moisture during high activity and insulates during low activity — including when damp.

• Unisex slim fit; fabric stretches in width for a close, non-restrictive fit.

• Long raglan-style sleeves for unrestricted arm mobility.

• Densely knitted shoulder panels for improved carrying comfort under pack straps or load-bearing equipment.

• Flat seams throughout — no chafing against the skin.

• Low odour retention; typically requires airing rather than washing after use.

• Made in Europe.
