Seal Line Bulkhead Compression 5L Dry BagInnovative compression maximizes limited hatch space.Offering a fast and easy way to maximise the use of limited space, their waterproof Bulkhead Compression dry bag boasts an innovative compression system, a durably waterproof PurgeAir valve, and stow-friendly materials, resulting in a space-optimizing dry bag for use in boat hatches.Specs *Smarter compression: Unlike conventional systems that pull against seams, their 2-strap continuous strap system encircles the bag to minimise seam strain, maximising durability for dependable protection. *PurgeAir-equipped: New waterproof valve helps the bag compress further once it\'s been sealed. *Durably constructed: Fully welded seams result in stronger and more durably waterproof construction compared to sewn-and-taped seams. *Tight, simple sealing: Updated DrySeal roll-top closure makes it easier and more intuitive to achieve an optimal seal. *Stow-friendly: Made of durable materials that help the bag slide smoothly in and out of hatches. *Oval bottom: Stable shape won\'t easily roll around; it\'s also easy to store, stack, and pack. *PVC-Free: Materials have a reduced environmental impact over vinyl-coated materials.Product SpecsWeight (Standard): 4.6 ozWeight (Metric): 0.13 kgWidth (Standard): 4 inWidth (Metric): 11 cmLength (Standard): 7 inLength (Metric): 17 cmHeight (Standard): 10 inHeight (Metric): 25 cmVolume (Standard): 305 cu. inVolume (Metric): 5 litersPVC-Free: YesClosure: Updated Dry Seal dual-strip roll-down Material(s): 70D/140D 7.5 oz. polyurethane-coated ripstop nylon body
