Waterproof roll top backpack

• A waterproof roll top backpack made from 30 litres of sealed PVC, with one main volume that rolls down and buckles at the top, and the waterproofing in the material rather than a finish.
• Keys, pass and phone come out of a welded, zipped front pocket instead of unrolling the main body in the rain.
• Padded shoulder straps and a haul handle let you carry it like a rucksack, which makes 30 L workable on a bike or a station platform.
• Pull the side compression straps in on a half load and nothing shifts behind you when you stand on the pedals.
• A plain grey over black shell that reads as a commuter pack on Monday and as kit on a training weekend.

Waterproof roll top backpack in 30 litres of PVC

Ask on any tactical forum and the answer is the same: the dry bag goes inside the pack, or it replaces it. The drybag backpack takes the second route, with 30 litres of PVC, a roll-top closure and a padded harness instead of a single sling. The welded front pocket is the part you notice at 6am, because the phone and the pass come out without opening the sealed compartment in the rain. Side compression straps pull a half load in so the weight stays against your spine on a bike, and the D-rings take a bit of kit clipped outside. Grey over black is quiet enough for a commute and plain enough for a wet weekend on the hill. One volume, one closure, nothing clever to break when your hands are cold.
