Sea To Summit 4 Liter Ultra-Sil Dry Sack

Fabric:

• Made of Ultra-Sil™ nylon, a polyurethane coated Siliconized Cordura® for ultimate waterproofing and maximum durability.
• Like all manufacturers of roll-top, fabric dry sacks, Sea to Summit recommends that sensitive electronic devices be ‘double bagged’ (i.e. putting electronics inside one dry sack then placing this inside a second dry sack). For maximum protection, the use of a waterproof hard case should be considered.
• Avoid contact with sharp objects or subjecting the sack to high abrasion, as this could compromise the waterproof fabric.
• All seams are double stitched and tape sealed.

Insulation:

• Any roll-top dry sack must be closed properly to ensure water can’t get in. Begin by folding the Hypalon™ strip down first and be sure to have at least three rolls before closing the buckle.

Ventilation:

• Watertight, non-wicking Hypalon® roll top closure with stiffener at the top for a better seal

Sizing:

• Smaller sizes have flat bottoms, others are round

Features:

• Nearly transparent allowing good visibility of the contents
• Soft and flexible with a slippery finish for easy packing
• Sold Individually
• Super compact and ultra lightweight
