Agustinwrote a review of JanSport Katahdin 70L Backpack - 4270cu in on August 12, 2013
Familiarity: I've used it several times
The quality of this Jansport backpack was good. I liked the look of it (Grey with white straps). There was enough space to fit all my gear for a 5-day backpacking trip to the Isle Royale National Park.
My complaint has to do with with the quality of the shoulder straps. If the backpack is fully loaded (38 pounds) and you have to walk in excess of three miles you shoulders will hurt because there is no enough padding on the shoulder straps. I wish I would have spent more money and buy an Osprey backpack.
