Prometheus has it in the bag

I've traveled with this outside the country as well as more local adventures. This is thoughtfully designed, roomy, and rugged.

Mike Harrell
Smart duffle

This thing is a great shape for just stuff everything into. The extra zipped pocket is perfect for valuables. The day after I got it I took it on a weekend adventure motorcycle trip (camping, off-roading) and it was the perfect addition for a little more cargo space on the bike. Easily switch from backpack to duffle.

Holy grail of bags

Air tight bag. Solid construction. Use it for my gear in my car. Holds a lot of weight with no issues. Zippers and stitching is high quality. Air release is a great touch. A bag with a thousand uses. I know I will use it forever. Perfect SHTF go bag. Much respect ✊

Absolutely fantastic!

This bag far exceeded my expectations.

Heavy duty is chic

I have never been disappointed in the quality of PDW products and this duffel is no exception. This thing is bomb proof in every sense. I am currently using it on a 1,700 mile road trip. I have my entire sleep system, tentage, cot and toiletries in the bag with room to spare ( nothing worse than crawling into a wet sleeping bag after a long trek. I keep it on the roof of my car and I have had no problems with moisture leaking into the bag. And it looks cool and is functional!
