A 47-liter internal frame canyoneering-specific pack, the Shinumo, is the High Priestess of Imlay's line, offering excellent comfort in addition to canyon compatibility like no other. Big enough for long day-canyons carrying too much stuff, and for lightweight canyoneering overnights.
The Shinumo is the women's version of our Heaps Pack, built for smaller, curvier bodies. The pack body is 2" shorter, then made wider and deeper to reclaim the volume lost to shortening. The suspension has been re-engineered to fit women, especially smaller women. The hipbelt is shorter and curvier. The shoulder straps are narrower at the ends, but wide where they cross the shoulder.
