Sea To Summit Ultra-Sil Dry Sack 4 L

Sea to Summit Ultra-Sil Dry Sack 4 L is extremely light and compact waterproof dry sack. The material used is durable Ultra-Sil™ nylon, a polyurethane coated Siliconized Cordura® which is one of the lightest and toughest waterproof nylon fabrics available.

• Watertight roll top closure with stiffener at the top
• Soft and slippery fabric for easy packing
• Nearly transparent bag allows good visibility for the contents
• Double stitched and tape sealed seams
• Volume 4 liters

Remember to close the bag properly to ensure water can’t get in. Be sure to have at least three rolls before closing the buckle! This dry sack is intended primarily for use inside a backpack etc., not for boating or marine use. Ultra-Sil Dry Sacks should only be used to store sensitive electronic devices when used in conjunction with another, heavier-duty dry bag – the “double bag” method.
