With my aim to become an ultralight backpacker, I decided to bite the bullet and go for one of the growing number of lightweight packs and as I tend to be a try before I buy kinda guy, I opted for the readily available Osprey Exos 48 pack. In my first attempt at setting up this pack I managed to get all my equipment (including four days of food and three litres of water) into the pack but I felt that I was pushing the friendship a bit. Two more repacks and a readjust on how I was packing, saw me comfortably fit all my equipment at a full loaded weight of 14.7 kg (32 lbs). I found the pack carried my loads which varied between 10 kg (22 lbs) â 21.3 kg (47 lbs) comfortably and even at the heavier end of the range at no stage did the shoulder straps cut in to me. On the few days that saw the temperature reached approximately 32 degrees celcius (90 F) my back remained sweat free. This pack has no shortage of pockets. The large stretchy pocket on the back is ideal for holding the tent and other flexible material. The two side pockets hold typical Nalgene style water bottles or other similar sized equipment. The two shoulder strap pockets are ideal for things like hand sanitiser and cliff bars, and the waist pockets are also ideal for snacks and other small bits and pieces. However, I think that these waist belt pockets are one of the negatives of this pack with many of the Exos' competitors are opting for large pockets that allow more flexibility in packing. Overall this is a great pack and one that I would highly recommend. All Osprey need to do now is to increase the size of the hips pockets and this pack will be perfect.
