A decent bag fitting the bill for a Rocky Mountain ski trip. Main compartment compartment held a Nikon D90 with 70-300 f3.5, a Nikon 17-55 f2.8 and a GoPro II.
Easily accessible and adjustable waist straps, shoulder straps and the all important shoulder connecting strap. With the straps hunkered down allowed me to ski moguls and steeps while the bag stayed put not affecting balance.
Camera access is stictly from the back so not the easiest or quickest bag to pull from but then there's little risk of equipment escape due to a forgotten or loose front side zipper.
Bag easily fit under front airplane seat with room for feet on either side. A top mounted pull handle made for helpful access in a crowded airplane as well as assisting the strapping on/off process over bulky ski apparel.
Because of the impeded camera access I don't think I would buy this bag but I would rent it again for a similar rigorous trip.
