Sea to Summit Ultra-Sil Dry Sacks

STS Ultra-Sil Dry Sacks

Sea to Summit Ultra-Sil Dry Sacks are a super light weight dry sack designed for use inside a pack. Made from Siliconised Cordura for maximum durability, Ultra-Sil Dry Sacks will keep your pack light and you gear bone dry!		Ultra-Sil Dry Sacks use Beamis Seam Tape, which is the highest quality available
All sea to Summit Dry Sacks use Hypalon instead of webbing on the roll top closure. Hypalon does not wick water into the closure unlike webbing		Ultra-Sil Dry Sacks are constructed using Coats Brand threads, which are the global leader in threads and sewing products. We use a short stitch length to ensure a high degree of quality
Roll top closure is precisely designed with a longer Polypropylene stiffener opposite the Hypalon, which helps seal the closure flat, which further improves watertight seal and means that the roll top closure is less likely to unroll when under pressure		A custom designed shorter symmetric, side release buckle can be clipped together either way around, which also aids keeping the roll top closure secure
All seams are top stitched, which keeps taped seams flat and even		1 L, 2 L & 4 L are flat rectangular shaped design. 8 L, 13 L, 20 L, 35 L are round base design. All sizes in the Nano dry sacks have an oval base design.

How about this - Feather light, bone dry! We believe these are the lightest dry sacks ever invented. Not only is the weight revolutionary, but the hypalon roll top and siliconised finish eliminates wicking to ensure a dry seal.

Our Verdict

Getting very good reports about the Drybags from customers. These Sea to Summit (STS) Ultrasil Drybags are a similar product to POD Ultralite Drysacs - the difference is that the POD version has a larger buckle fastener and a haul strap across the base, this makes the POD sacs a few grams heavier in each size.
