Great Running/Biking Vest

  • Gender: Male
  • Familiarity: I've used it several times

This vest was purchased for a forthcoming adventure race and although I have not used it yet for that I wanted to give my first impressions. I have used this for mountain biking and trail running upto 2 hours duration. I have also used it between 40-90 Deg heat. So far I have nothing but awesome things to say about it, no chaffing, no bounce, little thermal heat stress and very customisable. I have purchased UltrAspire Collapsible 500ml Bottle/Straw for the front pockets which work really well for hydration on the move. All in all I think this is vastly under-rated and compared to Nathan/UltrAspire/Salomon products is amazing value.

Cannot reccomend it enough.

Does it come with a bladder and if so how big?

Responded on

No bladder included. Can fit a 1.5L bladder easily in, much bigger is a little tight.

Volcanic 50k

  • Familiarity: I've put it through the wringer

Running was the poor man's sport until a few years ago. Now it's a fad and running events, shoes, and apparel are priced for the fashion minded yuppy. Fortunately, you have Mountain Hardwear which still makes moderately priced items like this race pack. It was one of the few that could be had for less that $100. I used it on a grueling 50k trail race that lasted 6+ hours instead of the usual 4 hours. Fits well, no bouncing around. I just don't understand why there are loops for a bungy system but no bungy system.
