Sea to Summit Ultra-Sil Pack Liner
The Ultra-Sil™ Pack Liner won the prestigious Backpacker Editors' Choice award in 2006 and this award winner is an excellent solution for keeping contents of your pack dry. It's made of 30D Ultra-Sil™ CORDURA® brand fabric, making it super lightweight and is an oval shape to fit inside packs easier. The extra wide opening roll-top closure folds in three before being rolled and sealed with the low profile buckles. We've used bright colors to help with visibility when packing and unpacking, and a 50L, 70L and 90L size range to cover all options and bag sizes.
Keep it inside your pack and away from hard edges and corners.
