UltrAspire Quantum Belt

photo: UltrAspire Quantum Belt lumbar/hip pack

The Quantum belt is in a category of its own. It is lightweight, low profile and can carry enough nutrition for several hours. The product could be used for quick 2-4 hour hikes where you don't want to lug around a bulky pack, or for running races on sporadically supported courses.


  • Lightweight
  • Low porofile
  • Storage for hours
  • Race bib hooks


  • Can be a bit abrasive if worn against skin


*Disclosure: I own a running specialty store and UltrAspire is a brand that I sell. I was given this product for review purposes and was able to keep it.

When I first tried this out for a 1.5 hour run I was concerned I would be picking it up from around my ankles. However, by the end of the first mile, I forgot it was there. It is designed for men and women and comes in three different sizes and has an adjustable waist strap in back to customize the fit.

I really put it to the test for a 30k race I was running. While hydration was plentiful on the course, the nutrition was sketchy. So, I used the Quantum belt to carry my own food. It easily held two Clif Bars up front in the waterproof pocket and four packs of fruit snacks in the back two pockets (2 packs/pocket). With only three pockets total, its such a simple design and so handy. I also found the adjustable strap in back a very useful/secure place to stash my gloves.

I've used it several times since and there are no signs of ripping or tearing. I'd recommend this for runners and hikers who want to go fast and not be bogged down by a cumbersome pack.

Source: tested or reviewed it for the manufacturer (I was able to keep the product)
