This has to be the MOST comfortable pack, fully supporting, and doesn't move around. I have used a bunch of other packs - that seem bulky and arn't made quite as nice as these are - being lightweight and carry a lot of paint. It has not torn and is definately constructed well.
It *could* use a barrel squeege holder, but really - I have a coil up one that just fits in one of my pockets anyways.
This is an excellent product - it may cost a bit more than some of the other products, but its well worth its value. Next to a mask, this is something you dont want to skimp on, and is well worth it - there is nothing like your belt breaking during a match when three guys come over the hill and you have to reload quick.. =)
