This bag is quite rad!

I love being able to put bars, phone, guide books, wallet, etc. in this bag. It's really convenient and I love the splatter paint design on the hip belt!

Favorite piece of Appalachian Trail Equipment

I am in love with this pack. It was my number one piece of equipment on my thru hike...making all my most important stuff assessable and safe at all times...Once I was finished it became my everyday pack even acting as a babysitter for my grandchild’s bear-bear! I can’t say enough about this phenomenal pack!

Diane C ⭐⭐⭐⭐⭐

This was a last minute purchase for my 1000 mile trek on the PCT. It quickly became my favorite. It was very comfortable and made easy access to things I didn't want to have a hard time reaching such as snacks, chap stick, and a small journal. This will now go on all my treks!

Love it!

I use the summit bum with the comfy strap for day hikes and would have loved to have known about it before hiking the Appalachian Trail. I'm definitely taking it on the CDT! It's very durable and the extra convenience can't be overstated. 10/10 I recommend this product.

Anonymous ⭐⭐⭐⭐⭐

I love my summit bum! It's the MVP of my hikes now. I can keep my snacks, compass, phone, hand sanitizer, and map close at hand, and keep them there even when I remove my pack. I'll never hike without it!
