The predecessor to the Gregory Baltoro 75 won countless awards for being the most comfortable high performance pack. So why mess with a good thing? To make it even better of course. The Baltoro 75 has improved functionality within the feature set, increased pack volume and an updated suspension that carries better and more comfortable than ever before. Gregory didn't even think they could improve on perfection, they dare you to tell them the Baltoro 75 isn't the best pack you've ever worn. Small fits a torso range of 16-18 in. and Medium 18-20 in.
