An excellent balance of durability, weather-resistance, and weight, the award-winning Sea to Summit Ultra-Sil Dry Sack is a reliable, ultra-lightweight option for organizing and protecting backpacking gear. The dry sack’s Ultra-Sil 30D siliconized Cordura nylon fabric is highly durable and is coated for high water-resistance. Fully-taped seams further ensure weather protection and reinforced stitching bolsters strength. A Hypalon roll-top closure provides wide-open access to the sack’s interior but battens down the hatches by using an internal stiffener to create a secure seal. Delrin buckles emit a positive “click” when connected to confirm that you’ve properly protected contents. Oval shaping at the bottom of the dry sack provides structure and makes packing easy. The Sea to Summit Ultra-Sil Dry Sack is available in your choice of colors and 1L (4.3" x 9.4"), 2L (5.1" x 11.4"), 4L (5.9" x 13"), 8L (6.7" x 18"), 13L (8.6" x 21"), 20L (10" x 24"), and 35L (12" x 27") size options.
