High quality in construction. Extremely light weight and super durable.

– Wayne S., ★★★★★

This full size roll top dry bag protects the entire internal contents of your backpack. This is a good option if you prefer to use non-waterproof stuff sacks instead of individual dry bags. It is also nice as an extra layer in very wet environments. Multiple sizes are available.

This is also available in a heavier material with a handle for dual-use as a protective Airplane Case for checking your backpack on an airplane.

Didn't expect something this light to feel so sturdy, but the roll top closure keeps everything bone dry even when my pack gets soaked. It fits my full-size pack perfectly and barely adds any weight.

Joshua ★★★★★ Sep 15, 2026

Took this on a rainy three-day hike and everything inside stayed bone dry, even after the roll top got dunked crossing a creek. It's shockingly light for how tough the material feels, and it fits my full-size pack without adding bulk.

I've finally stopped double-bagging my clothes inside my pack. The roll top seals tight and the whole thing weighs next to nothing, so my sleeping bag stayed bone dry even through a full day of rain.
