Review on IDRYBAG Waterproof Backpack Floating Dry Bag – 20L/30L, Roll Top for Dry Gear – Ideal for Kayaking, Boating, Rafting, Swimming, Hiking, Camping, Travel, Beach by James Salem

I needed a bag that could be both carry on and an efficient bag for a day trip on a snorkel boat. That fits the bill. It's small enough that I'm not overwhelmed, just enough for the beach or a day trip. I was mostly happy with it. The bag could use shoulder clips to keep it in place on long walks - I can build my own for future use. The zipped pockets inside and out were nice too. Not very happy with the inner pockets. The bag is quite thin front to back and most bulky items will just get caught in it if you're not very careful. The lining in the pockets began to tear almost immediately. Otherwise a good bag. Multiple convenient handle and hold options and a swivel and clip at the top allow you to attach the bag to your belongings so it stays secure if the boat tilts.
