- Who it's for
- Runners who want vest-free carry for training runs through longer races (up to 50K+), especially on trails and alpine terrain. Works best for efforts where drop bags or minimal kit can cover gaps in capacity.
- What people are saying
- Hosts consistently praise the no-bounce, no-chafe fit and the tendency to forget it's on. Durability gets strong marks across multiple notes, with several hosts reporting 12–18+ months of heavy use with no issues.
- Worth noting
- Noted as pricey, and one host flags it's awkward to get on and off. Capacity can be stretched (raincoat, poles, two flasks reported), but it has limits — one host added buttons to maximize carry.

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.
Recommended in Trail running
Fits essentials, calories, and one 500ml flask for 2–4 hours of high-alpine mountain running in fair conditions.

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.

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.

Matt Trappe, Brand Creative in Running
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.
