The Saltyroll is a dry bag that opens on both ends. But, it’s really more than that. The sewn daisy chain is convenient for strapping onto existing vertical or horizontal lashing points or using straps to fasten in places like above your handlebars.
The strapping also lines up with the Revelate Designs The Harness. It’s ideal dimensions make it well suited for smaller shelters and bivvies, or compact sleeping systems. A lightweight 3 season bag and single wall tent/tarp should fit, but you may want to use compression sacks inside.
Should you need access to smaller items, just pack ’em near the ends for easy access. No need to pull everything out to get at gear on the bottom. This is a really versatile bag, especially when used in conjunction with other pieces of the Revelate system.
Bear in mind that the 200 denier fabric is not rated for constant abrasion like moving brake levers and gear shifters.
