Ships in 1-2 business days | Based in Norway | Est. 1887 Lightweight moisture management for high-intensity cold weather activities This base layer t-sleeve mesh shirt provides insulation and breathability. An open-weave "fishnet" construction means perspiration vapor can be rapidly transported to the outer layers and dry faster then a solid knit construction. The PolycolonA(R) mesh provides 4 to 6 times the insulation value of solid knits while keeping moisture off the skin. The solid knit inlay on the shoulder provides a comfort layer under pack straps. Polypropylene has a very high strength to weight ratio providing super light garments designed to withstand years of extreme use. Brynje Super Thermo garments are exceptional for warm weather use as well because of the thermostatic qualities of the mesh. Fit: Mesh base layers are generally quite stretchy in all directions and are cut long. As the girth increases, the length will decrease. This style is a Unisex fit. Generally the Women&&';;s sizes will be one size smaller than Unisex. For example a Unisex S is equivalent to a Women&&';;s M. _______________________________________ Sizing: Size Height Waist Chest X-Small 5&';1" - 5&';3" | 1.5m - 1.6m 27" - 29" | 68.6 - 73.7cm 34" - 39" | 86.4 - 99.1cm Small 5&';4" - 5&';6" | 1.6m - 1.7m 29" - 31" | 73.7 - 78.7cm 37" - 40" | 94 - 101.6cm Medium 5&';7" - 5&';9" | 1.7m - 1.75m 32" - 34" | 81.3 - 86.4cm 40" - 42" | 101.6 - 106.7cm Large 5&';10" - 6&'; | 1.75m - 1.8m 35" - 38" | 88.9 - 96.5cm 42" - 44" | 106.7 - 111.8cm X-Large 6&';1" - 6&';3" | 1.8m - 1.9m 39" - 42" | 99.1 - 106.7cm 45" - 48" | 114.3 - 121.9cm XX-Large 6&';4" - 6&';6" | 1.9m - 2m 43" - 45" | 109.2 - 114.3cm 48" - 50" | 121.9 - 127cm 3X-Large 6&';7" - 6&';9" | 2m - 2.05m 46" - 50" | 116.8 - 127cm 51" - 53" | 129.5 - 134.6cm Weight: 4.1oz | 116.2g (medium size) *Weight may vary due to fabric variation Materials: 100% SchoellerA(R) PolycolonA(R) synthetic yarn, knitted into a 3/8" open weave mesh bluesignA(R) certified fabric Material weight: net 140g/m2 PFAS-Free Care: Hand wash or machine wash on gentle cycle with cool water.
