Overview

The Dynafit Speed Dryarn S/S Tee is a technical short-sleeve shirt built for high-output mountain sports. Its primary fabric, Dryarn®, is a high-performance polypropylene yarn that offers the lowest thermal conductivity and highest moisture transfer of any textile fiber. Combined with 11% elastane, the shirt delivers exceptional stretch and recovery, maintaining its shape through thousands of wear cycles. The seamless construction eliminates chafing and irritation, while the crew neck provides a classic, non-restrictive fit.
