I've been on a bit of a pack kick lately and sewed up two new ones in the course of about a month. I shared pictures of my "Franken-ruck" recently but what follows was a previous work.
It's a bit more detailed and includes a foam framesheet in a tight-fitting sleeve, a probe/shovel handle/saw pocket, a daisy chain on the front, two rows of PALS on the bottom, simple hip stabilizer belt, and hooking top closure mechanism.
Fabrics employed are 1000d Cordura (both coated and uncoated), 200d Cordura, VX-21, spinnaker, silnylon, and then various bits of webbing and other notions.
I've had this out for one long day in the backcountry with standard avalanche gear, ten essentials, et al and it absolutely swallows everything up. I carried my split in a-frame very comfortably (using ski strap at top tips).
I did not include a small organizer pocket inside nor do a lid for this pack and I could see that being a future update.
Weight is +/- 20 oz.
Volume is 37 liters up to the collar
