Nice pack!

"It performed very well on my SHT thru-hike! Very happy with the pack."

— Randy T. (5/5)

Fanny-tastic!

"Took it recently on 5 day backpacking trip where it rained on and off everyday—Contents stayed dry the whole time! The inside card pockets was a nice addition. Perfect for IDs and credit card. I used the other pocket for a sheet of pre-cut leukotape. Was great for easy access. The outside rear pocket is also great for a phone. I was nervous it could fall out easily but it’s the perfect depth/width to where it stays in place without issue. We had a lot of scrambling and elevation change—phone never moved. Potential improvement— the back panel where the strap goes through was TOUGH to get the belt through. I attempted for about 10 min before having my husband do it for b/c my fingers weren’t long enough. I wanted to have my backpack hip belt clip connect through it but didn’t attempt since the space was so narrow and it’s hard to reach the middle of the back panel to clip it together. So I just wore it with the belt it came with which worked just fine. All in all, despite the initial putting the belt though the loop- I love the fanny pack!"

Ultra Summit Bum

"Very well made and light weight. The comfy belt is very nice…like it’s not even there. What is the space between the front padding and the bag itself is for?"
