Bought the Tempo 50 pack 4 1/2 years ago, and still a great pack. Have backpacked with it overseas. packing t shirts, shorts,undergarments, socks, toiletries, etc big enough for a week I find. I lost a strap due to baggage handlers at one point and Blackwolf replaced it no charge. The quality is great, better than my Northface Surge and Deuter futura. I recently bought a Blackwolf Mountain Ash 65 for extra capacity for a trekking adventure, but they are worlds apart. The appearance and durability of the Tempo is far better.... If you after tough, durable & cool looking pack (make sure to get green) look no further. Capacity is the only reason I may not buy another one.
