Finally pulled the trigger on a PROTECH Vest this weekend. I was really looking at an AVY Vest but with no dealers close by its hard to make a purchase like this with out being able to try it on and see all the features. So far I love the thing, fits nice, lots of nice features. I really think they under measure the volume of the storage bag of the vest, The Snowpulse website says it is only 10L and the tag on the bag says it is 15L, I currently have a Dakine Helipro wich is 22L and Im sure I will be able to pack all the stuff I can carry in my Helipro in this vest no problem. Really hoping that I never have to use the airbag on this thing, but its so cool!! So to anyone looking at this bag but worried that the carrying capacity is limited, take another good look at this product!
