?I used the Primero guiding on Mt. Rainier last summer and love it for that kind of mission. I got a lot of nice comments from clients and random climbers alike saying that this pack marked a true rededication of The North Face to pack building. Doesn't get much better than that in our inbred, backbiting industry. The expanding pocket is awesome. Pack lid is very well designed and thoughtfully engineered.? - Pete Athans, high-altitude mountaineer, best-known for being the only non-sherpa to summit Mt. Everest seven times.
