Eco Summit Bum *Best Seller*

ECO SUMMIT BUM

The ECO Summit Bum is crafted mainly from ECOPAK EPX200, or UltraGrid, which are 100% recycled powerhouses. Say goodbye to the ordinary; embrace the extraordinary.

This is THE pack. This is the pack I designed in 2016 because the market really only had generic fanny packs, but backpackers needed something a little more special, like a backpack sidekick.
Our flagship model has spawned imitations, but none match the fully-loaded brilliance of the Summit Bum.™

This is the apex of lightweight durability and function, a design that holds up to everything you throw at it, without holding you back.
Clip it onto your hip, wear it on your chest, or sling it over your shoulder.
The possibilities are endless.
It's a clean and simple design adapts effortlessly to your every need. Adaptability is key.
The ECO Summit Bum features a removable strap and two attachment points on the back, letting you customize your adventure style. It's not just a fanny pack; it's an extension of your backpack.

Pair the ECO Summit Bum with the Comfy Strap™ for the pinnacle of adventure luxury. Because your journey should be as comfortable as it is thrilling. I promise the Comfy Strap is absolutely worth the couple of extra ounces.

• Bonded seams in main compartment

Great pack from a local company

"Love my new Thrupack. Had enough room to hold my things walking around town or adding it to my bag and while hiking. It also feels great supporting a local anti-fascist company. #radicalleftscum4life"

Awesome little bag

"Love this for backpacking or just using as a sling for around town. Fits a lot of stuff and the comfort strap is so nice! This one is actually a gift for someone because they borrowed mine and loved it too, haha"

Love my thrupack

"This is my second I want one less bright colors to use for work, so my pockets aren't full of stuff when responding to emergency calls, my other job I will use to hold snacks and tools. I got my first for easy storage of things I needed quickly when doing search and rescue. I can wear it hiking, climbing in a harness, holds just enough and is comfortable to wear for long periods. I started to use it mountaineering which is clutch, easy to access to sore things I want quick access to, I don't have to deal with my pack straps covering my cost pockets making things hard to get to, the thrupack allows me to move it easily to spot I can get quick access."

Love it!

"A great pack for any time I’m running around, whether it’s protesting or just running errands. Love how well it’s made, the roominess, and the versatility and security it provides. A really great pack!"

— Michelle S. (5/5)

Great as a sternum strap pack

"This Summit Bum pack is my third and each are well made and suit my needs well. I have one for each of the seasons I engage in activities here in Colorado and each are used with backpacks. I carry them attached to the sternum strap of each backpack and fill them with season appropriate items. For example, my Winter Summit Bum carries snow science items which I like to have handy like a slope angle meter, snow crystal card, etc. Thank you for making such a robust and well thought out product!"
