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!

Jason Wargolet
Almost perfect

Used the 60L duffle for a kayak camping 3 day trip recently. Size fit all our sleeping gear, plus a few cooking items well. We did get some water in the bag, but that could have been user error by not ensuring the zipper was fully secured. I water tested it in the bathtub and shower after and had zero water drops inside. Only complaint would be I with the T handle on the zipper pull was wider as it can come undone from the keeper a bit too easily with movement. Going to buy another one tho as the backpack option to carry and overall design and performance is great.

NICE Duffel!!!

This is a nice sturdy duffel bag that is plenty big to carry a bunch of my gear but also weather and dust proof enough to ride on my Land Cruisers roof rack through sandstorms, torrential rain, or blizzard. The backpack straps also make this line of bags great for airport traverses as well.
Cheers to PDW for another great design!
