The Singi Trekking Shirt is made from the same cotton-polyester blend as Fjällrävens most popular jackets and pants, making it a particularly durable choice for a shirt. This is an excellent option for those who spend a lot of time outdoors and enjoy trekking. The Singi Trekking Shirt stands out in its category as the manufacturer highlights its compatibility with Greenland Wax treatment, which enhances wind resistance, improves water repellency, and increases durability. The shirt is delivered untreated, and you can choose whether or not to go for the wax treatment. - Regular fit - Made from comfortable, quick-drying, and durable cotton-polyester fabric (G-1000) - Pre-washed for a soft feel right out of the package - Two chest pockets and one sleeve pocket - Sleeves can be rolled up and secured with buttoned straps - Mesh-lined ventilation openings under the arms and beneath the back yoke flap - Back length: 82 cm This product does not contain PFAS compounds.
