Best Black Diamond waterproof shells
Among these three Black Diamond shells, choose the Fineline Stretch for a pocket-stowing 2.5-layer design. Consider the Highline Stretch for more pockets in a three-layer shell, or the Strataline Stretch for a simpler three-layer layout. Each includes underarm ventilation.
Based on 518 included owner reviews.
The differences that matter
The Fineline is listed at 320 g, the Highline at 360 g and the Strataline at 352 g. The small gap between the two three-layer options means storage layout deserves more attention than the weight difference. The Highline adds chest pockets and an internal stash pocket.
The Strataline focuses on two hand pockets and a drop-tail silhouette; the Fineline explicitly offers a climbing-helmet-compatible hood and self-storage. This is a guide to three men’s models with owner evidence, rather than a ranking of every Black Diamond shell or membrane technology.

Choose around your needs
Start with the Fineline for a compact carried shell, the Highline for more storage or the Strataline for a simpler three-layer option. Try the hood and pockets with your pack or harness. Use owner evidence to identify fit questions rather than treating one construction as universally better.
