I have the previous generation of this pack but it looks like the only major difference is that you can now remove the top cover, which is awesome.This pack is perfect for cragging. The 45L bucket + top lid holds: my full standard trad rack, sport rack, two pairs of shoes, harness, chalk, first aid kit, my 3L platypus water system, some food, a big rain poncho and a jacket or extra layer. everything packs in tight with the straps and the suspension system is awesome and comfortable. The fabric is super thick and abrasion proof.The lid on the previous incarnation of this pack is pretty much split into two pockets one inside (great for wallets, has a key loop) and one outside (easy access for guides etc).you can put the pack on without even taking off your harness and the hip belt (which is also removable and dynamic) has extra gear loops!Perfect size. Comfortable. Strong. Truly Epic.
