Backpack Ventilation Frame UL2 (Best Seller)

I love it. The frame is light feels comfortable on the back and let your back really breathe. Only one reason why I gave four stars. The little clips were it locks they keep popping out. They should redesign where it clipps. Other than that, it's a great product.

We have been using them for a few months now and love them! They definitely help keep your back cool while hiking. Would definitelyrecommend!

Works, but the jury is still out. I walked with a 30 pound rucksack and it altered the weight distribution a little which I need time to get used to before I recommend it to my peers.
