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.
