The Sea To Summit Ultra-Sil Dry Day Pack is a super light and very packable rucksack that is 100% waterproof. It uses the classic roll top dry bag closure ensuring a watertight seal. This 20 litre pack is ideal for light day trips or as a second pack when you're on longer trips and only need a small pack for the occasional day.
The Ultra Sil is made from a lightweight Cordura fabric that has impressive levels of abrasion resistance. All the seams are double stitched for strength and then taped for a waterproof seal. And it also comes with its own stuff sack ensuring it packs down neatly.
