Amazing Duffel! Better than X-PAC
Picked this over X-PAC after ordering both (black versions). I went with this due to the fact the interior color was a beautiful green vs an ugly gold on the X-PAC.
Water resistance is the same on both and durability wise I think the non X-PAC would handle abrasions better but if light is your thing you can save a few ounces with the X-PAC version that still looks great.
Overall if your torn, order this one and return it if you're not happy. But unless you don't like the interior green or prefer gold, order X-PAC.
FYI, Boundary offers a service called blackcart where you can order something without paying for it. If you return it in 5 days you'll be fine. I did this both bags and ordered both.
Hopes this helps others!
