Love this bag!

6 years ago

Exactly what I was looking for! My husband has a larger SealLine dry bag and I wanted one for myself. I picked this size because it's perfect as day pack and loved it because of the over-the shoulder strap. Its maiden voyage was an hour and a half trip, strapped to a paddle board, getting seriously splashed the entire time (and dunked more than a few times). It held up great. I know it says you shouldn't put phones or cameras in it, but I had both and everything stayed dry.

Great looking (and performing) deck bag

7 years ago

I teach SUP and purchased the orange plaid deck bag to carry my medical kit and other essentials for instructing groups. This bag has a flat-ish side that helps it conform to the board and sit under the nose bungees easily, and has good attachment points for a secure attachment to the deck. The purge valve is a nice addition to get that final air out and have the bag conform to the deck easily. Great new addition.

Waterproof and Durable

5 years ago

I'm a fly fishing guide and use this bag for the critical clothing, gear and electronics that I or my clients take in the driftboat on the river. I tested it and it's 100% waterproof. I stuff it in the compartment under my seat and yank it out and it has held up great.

Perfect Dry Bag

4 years ago

These were the perfect dry bags for my multi-day SUP trip. The addition of shoulder straps and handles made carrying gear from board to camp a cinch. They are the high quality that I have come to expect from Sealline products. Definitely recommend!

I wish I'd bought 2 of this versatile bag.

I took this 10L bag on a recent cross country motorcycle trip carrying small items I needed easy access to. It was exposed to torrential rains, mud and hail, and kept my gear dry. I love the lash points, and portability.

I kayak and bike a lot!! Very versatile and great for biking with groceries too!! It had a strap that simulates being carried like a messenger bag.
