This has been a very popular pack for many years - we lightened it up a bit for the Ultralight era and make it even lighter as in the Subpop ( no compression straps).

The Chasm at right has a Kangaroo pocket sewn on the rear combined with a roll-top feature so the pack can be used without a lid.

Volume: Bag - 3,000+ cu in plus top pocket - 300 cu.in. Below: A Partial Full Dyneema Chasm. Click photos for blowups. The only Dyneema is in the rear of the pack bag ( in the 2nd photo ) and the shoulder pads and bottom are Spectra. The 2 layer Summit Flap in photo is Full Dyneema, but the customer ordered his Hip-pack top in gray 420, like the harness side of the pack, the outer side of the belts, and the side pockets.

Pack comes with basic Hip-pack top or 2 layer summit flap, extension skirt or extra length single drawstring roll-top, 3 compression straps or Subpop Loop system, water bottle holders or lid bladder system.......

Below is a close-up of an un-Dyed Dyneema - the exterior of the P & G bayonets looking like any Yoke and Stabilizer system. Below that; the pack is shown with the P & G Bayonets pulled out and the harness converted to the simple 'Off the Shoulder' Guide Harness like the pack at left.
