The 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. We retained all the clever functionality of the original compression dry sack, with all the lightweight touches of our Ultra-Sil® technology.

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 while keeping it dry. It employs waterproof seams, a non-wicking roll-top closure and is super lightweight.
