Black Diamond Strataline Stretch Shell 3L

The Black Diamond Strataline Stretch Shell 3L is a lightweight mountaineering jacket built for demanding alpine conditions. Its BD.dry™ 3L 30K/30K membrane, fully taped seams and PFC-free DWR finish provide dependable protection from heavy rain, while stretch nylon supports natural movement on exposed ridges, glacier crossings and technical approaches.

Designed for high-output mountain missions, it combines underarm ventilation zips with a helmet-compatible hood, adjustable cuffs and secure zipped pockets. The regular fit layers easily over technical garments, making it a strong choice for mountaineers and other users who prioritize reliable weather protection, mobility and low pack bulk.
