  The only dry bag you will need

  The Big River series by Sea to Summit is the only line of dry bag you will need. It is perfect for beach days, backcountry hiking, snowshoeing, sea kayking, and bike packing. Tough bag. I have many in most sizes. Trust me, but it when it goes on sale, and you will enjoy it. I have never had any issues or defects with these bags.

  Solid Dry Bag - great balance of weight and durability

  Not as heavy as full on PVC dry bags, but sturdy enough for regular weather protection. It may work for full submersion - but I am not intending to use it for that. I use these for separating wet and dry wetsuits, clothes and towels on surfing, canyoning and diving trips.

  After using my Sea to Summit dry bag on camping and outdoor trips, I finally understand why so many people recommend it. The material feels lightweight but surprisingly durable, and it keeps clothes, towels, and electronics completely dry. What I really like is how compact and easy it is to pack. Once rolled down, it seals very securely and saves a lot of space in my backpack. The quality of the stitching and buckle also feels very reliable compared to cheaper dry bags.

  Parfait pour la plage

  J'ai acheté plusieurs sacs étanches de Sea to summit, surtout pour ranger mes vêtements dans mon sac. Par contre dès que je vais à la plage, en kayak ou en bateau, c'est ce type de sac étanche qu'il nous faut pour garder mes items électroniques au sec!

  While I haven't field tested yet. . they look to be great quality and a good size for my blackburn outpost cage mounted to my forks.
