I have had the chop shop heli pack for a few years. Its great for a day (and that is about all) good for my water reservoir (nalgene or camelbak) plus snacks for fuel. a few redbulls extra gloves, goggles, camera, and a shovel/probe. the waist straps are very long and sometimes inconvenient when theyre flopping all over the place - but if thats the only negative thing I can write then thats not bad!! Its an all around great pack that is very durable and keeps the elements out!! I have been in white outs for hours on end throughout colorado and utah, getting tossed around in the parks & drudged all over the mountain and it hasnt failed me yet! HIGHLY RECOMMENDED!
