Older model Dakine Heli Pack. Very narrow and tall. The Camelbak pouch holds my Dell mini 9, and plenty of room for more crap to carry! I snap the waist and sternum straps, but I only stress that the waist strap is fitted.

Can't find any pictures online of it - as it is Dakine's 2003-04 model, but I've seen the newer ones, and I'm sure glad I got mine when I did! I'll try and snap a picture.
