Sea to Summit Ultra-Sil Dry Bag

The Ultra-Sil Dry Bag is designed for water resistance in wet environments. It features taped seams and a non-wicking roll-top closure to keep contents dry, but it is not intended for submersion or prolonged exposure to heavy water pressure.

Yes, the fabric is semi-translucent. This allows you to quickly identify your gear without needing to unroll the closure, which is particularly helpful when you are packing multiple bags for a trip.

The oval base is a practical feature that prevents the bag from rolling around on uneven surfaces or inside your pack. It also allows the bag to sit more stably when you are loading or unloading your gear.

While the fabric is incredibly lightweight, it is constructed with Cordura® yarns to provide impressive tear strength and durability. It is designed to withstand the rigors of backpacking and travel, though it should be kept away from sharp, abrasive objects to prevent punctures.

To create a proper seal, fold the top edge over at least three times before buckling the closure. This ensures the non-wicking material creates a tight barrier against moisture.
