Fits large devices with thin cases. From Kickstarter to Amazon After a successful launch on Kickstarter, we delivered this backpack to customers around the globe. As a US-based company, we're proud to now offer it on Amazon. Our two biggest reasons for creating this pack: WATERPROOF PROTECTION WITH ZIPPERS: There's plenty of roll-top waterproof packs out there, but those can be cumbersome and difficult to organize your stuff inside. So we set out to make a versatile, zippered waterproof backpack.VALUE: Similar backpacks using 600D+ TPU and airtight zippers go for twice as much, and they don't have a waterproof front pocket. Having more functionality than other products on the market, yet still being more affordable equals added value. Also – these zippers are drysuit-grade and do not require "zipper grease". The incredible features and capabilities that this pack offers are hard to find – and you'll love it, GUARANTEED! If you're not happy, reach out to us and we promise we'll make it right.
