Arcteryx Phase SL Crew SS: a T-shirt for everything The Phase SL T-Shirt is more than just a T-Shirt! Feel it is a breath of nothing (only about 90g weight) - a warm nothing! The Phase SL T-Shirt insulates over a wide range of temperatures and can be used all year round: in winter as the lowest layer, in summer alone. The Phasic material absorbs sweat & moisture at lightning speed and transports it further, or dries again just as quickly. The material retains its insulating properties even when wet - this keeps you warm even after a sweat-inducing activity, even during subsequent breaks (e.g. sitting in a hide), and the functional underwear dries again by transporting moisture to the outside. Pleasant smell Synthetic fibre functional underwear often has the reputation of quickly developing an unpleasant odour: In this respect, the Phase SL T-shirt also differs from the competition: even after days, the odour development is minimal to non-existent. For every outdoor activity We ourselves use this T-shirt for almost every activity: be it hunting all year round, jogging, cycling, everyday life and even snorkeling (sun protection for the shoulders) and as additional insulation under the neoprene suit when diving. Even after 10 years of use, we still haven't managed to apply the shirts!   Details: extremely light - approx. 90 g best moisture transport breathable rugged quick drying minimal odour simple machine wash TeiJin Phasic material Material identification: 100% polyester
