In addition to the newly introduced Khard packs, Arc’teryx has also introduced a larger Recce class pack called the Khyber. Offered in 50 l and 80 l sizes, they are available in standard LEAF colors of Crocodile and Urban Wolf Grey as well as MultiCam.

This image should give you a rather rudimentary size comparison for the two models.

Here, Arc’teryx designer Dan Green goes over the philosophy behind this great pack and its little brother the Khard. He says in the video that they started over from scratch and I can attest to the amount of development that went into these new packs. Not only did they put a lot into them but they also had the foresight to not put every feature they could think of into them.
2013 LEAF: KHARD PACK from ARC'TERYX on Vimeo.
These are very lightweight packs with the Khyber 50 weighing in at 1.8 kg / 63 oz and the Khyber 80 at 2.2 kg / 78 oz. This is thanks in part due to the C2 composite construction suspension system which is a simple, yet effective deign that is low on bulk and keeps the pack close to the wearer’s back. Like it’s smaller brother the Khard, this pack is at its core a mountaineering pack and it’s sleek design relies on internal and external lash tabs and daisy chains rather than PALS webbing to attach additional loads. The Khyber also integrates a removable top lid with hydration ports and external compression shelf.
