I bought my Klim ABS Escape 15 from Cooke City Motorsports, I test fired it successfully & repacked it.
I was able to fit the following from my DeKine pack - first aid kit, emergency blanket, safety pack (w/ matches, compass, mirror, firestarter, leatherman, flashlight & batteries, rope, duct tape, whistle, hand warmers), spare goggles, gloves, & snacks consisting of candy bars, energy bars & trail mix.
I was ableto make this all fit in the Escape 15.
I am pleased to say the pack wears more comfortably than the DeKine Heli-Pack & it doesn't seem overly heavy or noticeable.
I was also able to strap a Black Diamond shovel on the back of the pack.
If you can swing one I would highly recommend one.
I know The Sled Shed in Tacoma also carries them - they are sold out on the Escape & have the Freeride in stock.
I ordered from Cooke City because I wanted the extra room of the Escape model.
Good Luck in your research.
