Based on the success of our Compression Dry Sack, we’ve made a lightweight version from 30D Ultra-Sil®. We retained all the clever functionality of the original compression dry sack, with all the lightweight touches of our Ultra-Sil® technology. The Ultra-Sil® Compression Dry Sack compresses gear to one-third the volume while keeping it dry.
- Ultra-Sil® 30D siliconised high-tenacity CORDURA® tylon fabric for exceptional strength
- Ultra-Sil® fabric has a 2,000mm waterhead
- Waterproof seams, double stitched and fully tape sealed
- Waterproof and air permeable eVent fabric base
- Hypalon closure does not wick moisture
- Reinforced stitching on all stress points
- Air compresses out, water cannot get in
- 40% lighter than the 70D Compression Dry Sack
Proper Use:
- 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.
- Avoid contact with sharp objects or subjecting the sack to high abrasion, as this could compromise the waterproof fabric.
- 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.
- Not intended for situations where dry sack will be submerged under water.
NB: While our Drysacks are designed to protect gear from rain and water dunking accidents they cannot guarantee to protect electronic gear when fully submerged. For this we recommend fully rated IPX standard diving protection cases.
Technology
eVent® is a proprietary waterproof/breathable membrane fabric. Like all waterproof/breathable membranes, its micro-fine pores allow the passage of water vapour, but not liquid. There are a number of waterproof breathable fabrics available, all with different characteristics. Traditionally, waterproof/breathable PTFE (polytetrafluoroethylene) membranes got clogged easily by body oils, which rendered them useless after a little use. The solution was to add a PU backing to protect the PTFE membrane. When thin enough, PU still allows vapour transmission, but at a much lower rate. Some manufacturers avoided the membrane and just used a PU coating. The PU has to be relatively thick to ensure sufficient waterproofing, resulting in even lower breathability. The genious of eVent was to make the membrane oleophobic (oil repellent), meaning it wouldn’t clog with oils, therefore didn’t need the inhibiting PU layer. At this juncture, eVent® is the most breathable waterproof (20,000mm) fabric we know of. It...
Constructed using high tenacity fibre technologies, weight for weight, CORDURA® fabrics are exceptionally durable. Fact is, no matter the application, their fabrics are “best-in-class.” But more importantly, they have to pass their own stringent test criteria before they can earn the CORDURA® brand name. They’re available in a wide range of weights – from ultra lightweight to heavy weight. and CORDURA® fabrics come in many different constructions and textures. All in all, they’re the fabrics that make strong, long-lasting products even tougher.
30D Ultra-Sil® is a 30 denier 240T Nylon made from a high-tenacity Cordura® brand yarn. High-tenacity nylon is stronger and more abrasion resistant than standard nylon fibres.We use two different versions of 30D Ultra-Sil®: a Sil/PU and a Sil/Sil version depending upon its purpose and use. Sil/Sil 30D high-tenacity Nylon with silicone impregnated on both faces. Silcone impregnation works really well with lightweight fabrics as it improves fabric tear strength, abrasion resistance and packability. Siliconised fabric has a measure of self-healing when punctured. This fabric has a water resistance of 600mm and is used where a product needs to be water-shedding and water resistant but not necessarily waterproof. We use Sil/Sil for products where ultralight weight and strength are most important, such as our Ultra-Sil® Day pack, Duffle, Shopping bag and Sling Bag. Sil/PU 30D high-tenacity Nylon with Silicone impregnated on the outer face and a...
