The Wool Thermo (WT) mesh collection is made with Schoeller® 80% Merino wool and 20% polyester yarn providing excellent warmth when damp and superior odor attenuation. Brynje’s classic 3/8″ open weave design provides 4 to 6 times the insulation value of any solid knit by weight. The mesh design also allows moisture to transport to the outer layers in vapor form thus keeping you dry during periods of high activity.

Brynje’s WT Merino wool blend is very soft against the skin and has greater strength and durability than 100% Merino wool yarns. In addition, Merino wool’s great odor management properties means more uses between washings which protects both the garment and the environment. These garments are a great choice for virtually all conditions and activities.

    I still own a 20 year old, cotton, duofold Norse-Net undershirt. That shirt was worn whenever I exercised in cold weather, be it cross-country skiing or just running. Imagine my joy at learning about this wool, mesh t-shirt. It is a terrific shirt and excels over the old Norse-Net because of the merino wool. The wool is warmer than the cotton. It feels better against the skin. The top panels mean it is comfortable under backpack straps. Wool is still comfortable after absorbing sweat. My Thermo base layer is a staple of my winter clothing now, not just for athletic activities but also for leisure. It will go with me on every backpacking trip as the ideal base layer for both warmth and ventilation. I recommend it highly.

    I read about Brynje baselayers in a backcountry ski magazine. I purchased the reinforced T-shirt for downhill skiing this year. It worked very well with light layers and a shell. It moves moisture better than non-meshed fabrics and is surprisingly warm. After the trip, I carefully washed it by hand (see instructions) and bought a second T-shirt so I can use one every day on the next trip. It should work well for touring and backcountry.

    First garment of this kind and texture that I have every worn and I love it. I also like the extra long length in the waist that allows you tuck it in without it pulling out of your pants, and it provides a little more warmth to your torso if you use as sleeping shirt. I wore this recently on winter backpacking trip in Utah (25 degrees and 15 knot winds) as the base layer, under polypropylene shirt, and fleece with light wind jacket. I opened underarm vents on wind jacket. After 10 mile hike, this Wool Thermo Mesh kept my body dry and warm … while wicking moisture into the poly shirt and fleece so effectively that the fleece was soaking wet with mesh relatively dry/damp. This is lightweight, comfortable and soft against my skin, and very functional. I intend to make it a permanent part of my backpacking essentials. Be careful in following the washing and drying instructions as this wool will shrink or distort in a traditional washing machine or dryer.
