Made from environmentally-friendly, lightweight TPU fabric, it has electronically welded seams that provide strength while remaining virtually invisible. With an IP66 rating and a Class 3 designation from ROC Gear, it's 100% waterproof and suitable for quick submersion to depths of up to 3.0', though it floats if dropped in water. The pack utilizes OverBoard's Fold Seal System, so you can roll the top down towards the front 3-4 times and engage the buckle for a secure closure. This also creates a convenient top carry handle for use as an alternative to the bag's fixed top carry handle and padded shoulder straps. You can seal the pack from the side, too, by fastening the buckles and pulling the straps tight. The adjustable sternum strap and waist belt provide added support, while the comfortable back panel utilizes an air-flow design to keep you cool. Additionally, there are reflective strips on the front of the bag and both shoulder straps. Has a capacity of 30L.
