About this product

The Sea to Summit Ultra-Sil Dry Bag is a lightweight, packable storage solution built for camping and backpacking. It is constructed from bluesign-approved 30-denier Ultra-Sil CORDURA nylon, a fabric chosen for its balance of durability and low weight. A PFC-free durable water repellent finish provides reliable rain protection, though the bag is not intended for prolonged submersion. The roll-top closure fastens with a Field Repair buckle to create a secure seal, while the slippery nylon finish makes packing and unpacking straightforward. The translucent fabric lets you identify contents at a glance without opening the bag. An oval base keeps the bag stable and helps it pack efficiently inside a larger pack. Available in multiple capacities from 3 liters up to 35 liters (the 35 L version measures 22.2 x 12.6 x 11.2 inches), it comes in Tarragon Green. Sea to Summit backs the bag with a lifetime guarantee through the manufacturer.

What people are saying

Reviewers consistently praise the Sea to Summit Ultra-Sil Dry Bag for its impressively low weight, wide range of sizes, and reliable performance at keeping gear dry during backpacking, travel, and everyday outdoor use. The semi-translucent fabric is frequently called out as a practical bonus, making it easy to identify contents without opening the bag. The roll-top closure and slippery finish are noted as user-friendly features that simplify packing and unpacking. The most common criticism is durability: multiple reviewers report that the ultra-thin 30D fabric is susceptible to tears and pinhole leaks, especially with sharp or abrasive gear. Several users also caution that the bag is not suitable for submersion or paddle sports, and a few note that the internal plastic stiffener in the roll-top can snap and damage the bag from the inside. Overall, it earns strong marks as a lightweight organizer for backpackers and travelers, but those needing heavy-duty waterproofing are advised to look at sturdier options.
