BRYNJE: Unisex Wool Thermo Longs

The Brynje Wool Thermo (WT) Merino Mesh Longs are a highly versatile base layer engineered for cold-weather performance across a wide range of activities. Part of Brynje’s Wool Thermo mesh collection, these longs are constructed from a Schoeller® 80/20 merino wool blend that delivers reliable warmth even when damp, along with exceptional odor control during extended use.

Brynje’s classic 3/8″ open-weave mesh construction provides 4–6 times the insulation of solid knit fabrics by weight. The open mesh traps warm air close to the body while allowing moisture vapor to pass through to outer layers, keeping you dry and comfortable during high-output movement.

The soft merino wool blend feels comfortable directly against the skin while offering greater strength and durability than garments made from 100% merino wool. Natural odor resistance allows for longer wear between washes—extending garment life and reducing environmental impact.

Designed as full-length bottoms with reinforced knees for added durability, these super-light and stretchy longs are an ideal base layer for hunting, expeditions, and demanding cold-weather use. No fly design.
