Sea to Summit Ultra-Sil Pack Cover 50L to 70L

Silence the age-old backpacker's debate with the Sea to Summit Ultra-Sil Pack Cover, the featherweight champion of gear protection that weighs less than four ounces (113g) for the 50-70L size. This seamless waterproof shield transforms your vulnerable backpack into a fortress against downpours, using premium 30D Ultra-Sil™ fabric with CORDURA® yarns that repel water while adding negligible weight to your load. Whether you're tackling a soggy section of the Appalachian Trail or navigating unpredictable mountain weather, the innovative seamless construction eliminates potential leak points where traditional covers fail, keeping your precious gear bone-dry when it matters most.

What truly sets this ultralight pack cover apart is its thoughtful keeper strap system that prevents the dreaded wind-blown cover catastrophe, securing it firmly across your pack harness even in gusty conditions. The integrated siliconized nylon stuff sack remains permanently attached to prevent loss while compressing down to a tiny 10.5 x 7.5 cm package that disappears into any pocket until needed. For weight-conscious backpackers who refuse to compromise on protection, this Ultra-Sil cover ends the should-I-pack-it debate once and for all—because when your adventure turns suddenly soggy, you'll celebrate those four ounces of foresight that kept your expedition on track.
