Price: $149
- Who it's for
- Runners who want vest-free carry for efforts ranging from short training runs up to 50K+ races, especially when drop bags cover the gaps. Works for both trail and mountain running where keeping weight minimal matters.
- What people are saying
- Near-universal praise for zero bounce, no chafe, and a secure fit that makes it easy to forget it's on. Multiple hosts note it holds up well over a year or more of heavy use; one flags it's awkward to get on and off.
- Worth noting
- Pricey per one host, and capacity has a ceiling — longer efforts beyond ~50K likely require drop bags or supplemental carry. One host added buttons to extend carry capacity, suggesting the stock setup has limits some users work around.
Benji Wiederkehr's review
Fits essentials, calories, and one 500ml flask for 2–4 hours of high-alpine mountain running in fair conditions.

Bennett Levine, Backcountry Skier and Trail Runner
Been rocking this belt since it's first iteration. Many miles and wear, still holding up. I modified it by adding 3 buttons to the belt to max out carry capacity. Pricey but gets the job done. If I'm avoiding my vest, I'm bring my Raide LF 2L

John Bruno, Ultra trail-runner, ski mountaineer
This running belt is my go to for slightly longer outings where I want to carry exactly what I need, but still be extremely light. I’ve run 20-25 mile, big-mountain routes with just this belt. No bounce, no chafe, no nonsense.

Maggie Perkins, Runner and Professional Wildflower Admirer
Perfect for your 3-7 mile training runs when you need some water, a snack, and maybe a layer. It's awkward to get on and off, but once it's on, this puppy ain't going anywhere.

The perfect belt for carrying hydration and fueling for 2-3 hour runs. With the adjustable design, I often forget I am wearing it.

Absolute best piece of gear I have added in years! 18 months as my daily and long distance go to and holding up great!!!

Allen Au, Exceptional Amateur
When you don't want to run in a vest, this is great. I've done 25ks, 50ks, and 60ks in it, and can probably do a 50M if I have drop bags for other stuff. I've even ran with a raincoat and poles stuffed in it.

My favorite belt I've ever had! Can load it up with hydration, nutrition, phone, keys, etc and still somehow have zero bounce!

I was never a belt guy and now this comes on every run with me. I carry two bottles (1.2L) plus my phone, keys and a gel. I forget I'm even wearing it. It's lasted over a year and is still in great shape. Can't recommend it enough.
