Sea to Summit Ultra-Sil Compression Dry Sack [Size: X Small]

Sold Out

Retaining all the clever award-winning functionality of our original compression dry sack combined with all the lightweight benefits of our Ultra-Sil™ fabric technology, our Ultra-Sil™ Compression Dry Sack compresses bulky squishable gear and keeps it dry inside your pack. Made from Ultra-Sil™ 30D CORDURA® Nylon fabric with an eVent® fabric base, the air can be rolled out but can't get back in.

It's an ideal option for use inside a backpack during longer lightweight hikes, adventure travels, cycle touring and any activity where you need to maximise pack space by compressing your bulky items to one-third of their volume. It employs waterproof seams, a non-wicking roll-top closure and is super lightweight.
