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 than 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 provides a comfort layer under pack straps and to the chest area. 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. 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 4&';9" - 5&'; | 1.45m - 1.5m 25" - 27" | 63.5 - 68.6cm 28" - 32" | 71.1 - 81.3cm Small 5&';1" - 5&';3" | 1.5m - 1.6m 27" - 29" | 68.6 - 73.7cm 33" - 36" | 83.8 - 91.4cm Medium 5&';4" - 5&';6" | 1.6m - 1.68m 29" - 31" | 73.7 - 78.7cm 37" - 39" | 94 - 99cm Large 5&';7" - 5&';9" | 1.7m - 1.75m 32" - 34" | 81.3 - 86.4cm 40" - 42" | 101.6 - 106.7cm X-Large 5&';10" - 6&'; | 1.78m - 1.8m 35" - 37" | 88.9 - 94cm 42" - 44" | 106.7 - 111.8cm XX-Large 6&';1" - 6&';3" | 1.85m - 1.9m 38" - 40" | 96.5 - 101.6cm 45" - 48" | 114.3 - 121.9cm Weight: 4.0 oz | 113.4g (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 Made in Poland _______________________________________ Care: Hand wash or machine wash on gentle cycle with cool water.
