This is the HMG Dyneema Ice Pack 2400 (40L) size Medium (17-19" torso). This is the latest model with most of the seams internally taped at the factory. I have replaced all the plastic buckles except the sternum strap with nearly indestructible metal G-hooks similar to those found on other modern high end packs.

This is not the Standard Ice Pack made from Hybrid Cuben. That's a nice pack, but the fabric is not very abrasion resistant. This pack is made from full woven Dyneema and is the burliest I have ever used.

This pack is super light yet comfortable. Much more comfortable to me than something like the similar-sized Arc'teryx Fl 45

This pack has gear loops on the hip belt. The back panel aluminum stays can be easily removed to drop the weight by about 4oz. The hip belt can also be removed from its sleeve for even more weight savings.

The only obvious wear is a bit of orange Moab dirt

The pack retails for $500 and is usually excluded from coupons and sales. I'll ship it to you in the lower 48 for $350 via Paypal.
