What are you going to do with the ultimate surf pack if you’re not a surfer? Certainly, if you’re never going to do any kayaking, stand-up paddling, boating, beachgoing, waterfall gazing, swimming-hole swimming, walking in the rain, or any other activity near, in, or on the water, you don’t need a dry pack.

But if you’re a traveler who likes adventure, and won’t rule out getting a little wet, a dry pack makes sense. That’s why I’ve loved using the Dakine Cyclone II Dry Pack 36L Backpack.

And then, my husband (a better surfer than I am) promptly stole it from me and won’t give it back. It’s his favorite backpack, ever.

Made from 305D Cordura HP coated ripstop fabric, the pack has waterproof welded construction and a roll top to keep water out of the roomy main compartment. The front stash pockets are also welded, and have water-resistant YKK PU-coated zippers.

Like regular dry bags, roll-top packs often hold a lot of air, and you have to practice to learn how to purge air and roll at the same time. This pack has a two-way purge valve, so when you’ve sealed the bag, you can still purge air without having to start all over again.

With many dry pack backpacks, users have to make a choice between ultimate waterproof performance and carry comfort, because not all packs have comfortable shoulder straps that can keep you comfortable through a day (or multiple days). This pack has ergonomic shoulder straps (with an adjustable sternum strap), as well as a sweat-less breathable back panel.

If you’re a surfer, the integrated board-carry system is useful. If you’re not, it’s never too late to learn.

The Dakine Cyclone II Dry Pack 36L Backpack comes in black and camo and lists for $150 on the Dakine site.
