— A highly functional base layer for comfort in hot and humid conditions
Teton Bros.'s "VAPOR L/S" is a long-sleeved base layer designed to keep you comfortable even in hot and humid environments from spring to autumn. The material has been updated to make this a more user-friendly base layer. This item is packed with Teton Bros.' attention to detail and is easy to use for day trips, overnight mountain trips, and everyday use.
Features and Functions
■ Highly absorbent and quick drying, with a dry feel
The fabric is made of a combination of two types of polyester, which provides excellent sweat absorption, quick drying, and a dry feel against the skin. The border structure on the skin side has a water-repellent finish on the raised areas, so even if you sweat, moisture does not come into contact with the skin, keeping you dry in the summer and reducing the feeling of cold in the winter.
■ Antibacterial and deodorizing effect with Polygiene® StayFresh™
The cutting-edge antibacterial technology "Polygiene® StayFresh™" inhibits the growth of odor-causing bacteria, allowing you to wash your clothes less frequently while keeping them fresh, making it environmentally friendly.
■ Ensures range of motion and prevents slipping up
In addition to the raglan sleeves, panels on both sides expand the range of motion (ROM) of the shoulders and arms. The cuffs are equipped with thumb anchors to prevent the sleeves from slipping even during activities that involve a lot of movement.
■ Flat seaming for stress-free comfort
The seams are flat to reduce friction even when worn for long periods of time, and are gentle on the skin.
