The eVac™ Dry Sack utilizes 70D lightweight nylon fabric for strength and eVent® waterproof fabric on the base to allow eVac-uation of air for compression. It's an excellent option for storing and compressing clothes and sleeping bags without the use of straps. Just pack the items in, roll the sack down and push the air out to save valuable packing space within your backpack. They're an oval shape, making them perfect for sliding into the contours of your pack and all seams are double stitched and tape-sealed.

• Good for modular packing in a backpack?  Yes! Use them for all compressible items, squeeze the air out then pack the dry sack into a tight space so it does not draw air back in. Perfect for sleeping bags and insulated clothing.

• Suitable for paddle sports?  Yes – but the ability to squeeze air out of the dry bag does not gain you much in a canoe/kayak (the Lightweight Dry Sack may be a better choice). If you do use them, apply reasonable caution in sharp and abrasive environments.

• Waterproof?  The body of the dry sack is more than adequately waterproof (10,000 mm hydrostatic head) – just avoid submersion, as water can seep through the roll-top closure of any dry bag.
