The Wool Thermo (WT) Merino Mesh Long Sleeve Top is a highly versatile base layer designed to deliver exceptional insulation, moisture management, and comfort across a wide range of cold-weather conditions. Made with a Schoeller® 80/20 merino wool blend, it provides reliable warmth even when damp and superior odor control during extended use.
Brynje’s classic 3/8″ open-weave mesh construction offers an insulation value 4–6 times greater than solid knit fabrics by weight. The open mesh structure traps warm air while efficiently transporting moisture vapor away from the skin, keeping you dry and comfortable during high-output activity.
The soft merino wool blend feels comfortable directly against the skin while offering greater strength and durability than garments made from 100% merino wool. Excellent odor resistance allows for longer wear between washes—extending garment life and reducing environmental impact.
Designed with a shoulder inlay for improved comfort when carrying a pack, this long sleeve mesh top is an ideal base layer for hiking, skiing, expedition use, and everyday cold-weather wear.
