  1. Rated 5 out of 5

    Best piece of running gear I have purchased in years! Fits my phone, keys,headlamp,etc. Not to mention the fit. The only waist style pack to not move while your in motion. Excellent design.

    For all foothill training runs this season in Colorado (winter, spring), this belt has been a go-to piece of gear for me. Paired with a single Isopocket, I can carry my phone, a whistle, a small buck knife, the buff hood, an extra shoelace, gloves, toilet paper, 2 vfuels, and a Houdini windbreaker (merino wool long sleeve around waist). This setup is light out there. The ingenuity of the Max O2 Waist is evident the first time you put it on. Yeah, I am not the sharpest tool in the shed, but figured it out quickly and was impressed with the fit.
    Some cons; the little metal hooks for holding your bib number, me no likey. Only reason is when I run with a handheld and get sloppy, sometimes the bottle fabric catches on these hooks and rips/frays my handheld (It is hard for me to describe to my wife why I need to spend 30 dollars on a water bottle). I am a bib on your shorts kinda guy, so this is a con for me. Second gripe is that it does bounce a tad with me. I am a little dude, 5’5, 120lbs sopping wet. If I anchor it with a long sleeve merino wool shirt knotted below it, does not bounce at all. Once I figured that out, this piece of gear became a regular on all runs so far this season. Not sure what will happen with summer, maybe not stuff it as full as I do in winter and keep rumbling. Peace.

    Just added Quantum 2.0 to my collection. I needed a solution to hold iPhone 6 with Otter Box case while doing road speed work and short runs when no refuel needed and this is perfect! It even has room for gel or small amount fuel and key if needed.

    Highly recommended – little to no movement and hardly even notice it while running.
    Thanks!

    If there was ever a piece of gear that supports the ideals of “the more you know, the less you need”, the Quantum is it. Precise in it’s pocket arrangement, access and comfort, the Quantum handles the absolute essentials and nothing more. With a wind cheater tied on the waist, hand bottles and a little caffeine – this little pack can handle any hundred out there! It runs big- so size down.
