Best waterproof duffel

The bag is light and robust, the carrying system comfortable and it is really waterproof. Where I live you can swim across town through the river in the current over 1,500m. I do that all summer to come back home. I used the bag for a full year to protect my clothes and as a buoyancy device. It performs great.

All Terrain Duffel 60l

The duffel is well made and functional. The pack straps are comfortable. I’m climbing on and off boats all the time and the fully loaded duffel is easy to carry. I really appreciate the absence of flashy logos. The duffel remains low-key, but even a quick glance reveals a bombproof piece of gear. Excellent price point as well. Thank you!

Seems good.

The bag seems well made but I haven’t traveled with it yet .

Buy this bag. Right now.

My wife and I travel a lot, and we've been through the usual rotation of heavy-duty duffels. Started as everyone does with one named for an alpine feature, went to thinner ones named for a fossil for the weight savings, and haven't really been satisfied with either. We got this bag for a 3-week trip through Madagascar, and it performed beyond our expectations. Light, burly, keeps its shape well, easily removed shoulder straps for that stressful moment at check-in, handles in the right places, lots of tiedown options. Best of all, NO HUGE LOGOS. The design is chilled out and not a theft target.
If I had to come up with negatives, the hook & loop carry handle link attachment isn't as secure as it could be (a snap would help) and mesh packing cubes do not play nice with the TiZip. But that's it. If you're on the fence, get it and don't look back.

Excellent product

Excellent quality on this product. I am packing now for a trip to the Great Northwest. I am sure I will be able to test the water proofing of the bag!
