Price: $219
- 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.

Best belt I’ve used. Doesn’t bounce at all and holds everything you need for the distance.

Fits essentials, calories, and one 500ml flask for 2–4 hours of high-alpine mountain running in fair conditions.
Recommended in Mountain Running Carrying Systems
Most reliable belt that can carry about 20 ounces of soft flask, phone, gels headphones. Most importantly without any bouncing

If you wanna feel light and fast, this belt will get you there. All the storage you need, plus a 650ml flask in the back

Good for longer days in the mountains when you want a little less on your back to move faster

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.

It worked for Whistler and countless training miles, it will work for a fast 50k

Absolute most stable waist belt ever!
Recommended in Best Running Belts -2026
I use my Raide LF2 belt for longer runs when I don't want to bring a vest. It's a bit on the stiffer side but holds so much! I have fit my nutrition, 2 soft flasks, and my phone. Bonus for no-bounce.

My daily go to! I’ve rocked everything from mid week speed sessions to a 100k race in this thing and it’s outperformed any other piece of gear I’ve used!
Recommended in Products I Actually Use
For the runner who claims to pack light but somehow needs room for 17 gels, their phone, keys, and a few emergency snacky snacks

The Raide 2L belt is a must have for me. I have yet to find a vest that doesn’t bounce all over the place when I pick up the pace. With this belt, I can carry water, plenty of fuel, and my phone all while getting under 6 minute miles with no issues.

a little bit heavier and more stiff than the naked belt - but tightens to your waist like a belt! great for if im planning on using poles and need to use the bungees.

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!

My favorite piece of gear. Can carry up to two 500ml flasks in the back + poles and/or jacket in the belt loops. I carry my phone + easy access gels in the front. Adjustable, doesn't move around at all.

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.

I can’t say enough about this belt. I’ve done several ultras in it, and it’s never let me down. I’m able to store multiple gels and flasks in it, and there’s ZERO BOUNCE. I don’t understand it but I love it.
