I've been shopping for a laptop backpack and it's made me evaluate my current stable. I kind of have a thing for backpacks. Counter clockwise from bottom left: Camelback Lobo (2L hydration pack) - Used for shorter mountain bike rides. Camelback M.U.L.E. (3L hydration pack) - Used for most mountain bike rides and short day hikes. Gregory Inertia (4L hydration pack) - Used for epic mountain bike rides and day hikes North Face Hot Shot - My "country" daypack. Ancient pack that has endured a ridiculous amount of use and abuse. It started life as a book bag but graduated to general outdoor daypack use. I've also done ultralight overnights with it. It's currently my fishing backpack and is still solid despite its pathetic appearance. Guitar Research - Attaches to a gig bag. Was my "gig bag" but zipper pulls have broken and seams are blowing. POS! I occasionally use it to schlep tablets and tablet-related accessories. Dana Design Zoic - My last book bag and currently, my "city" daypack. I use it for luggage as I don't own proper luggage. North Face Terra 40 - This is my rock climbing pack. It's relatively lightweight and I've been contemplating using it for lightweight backpacking. Dana Design Bighorn - My favorite and most prized pack. Dana Design is defunct but their packs are legendary for the quality, comfort, and durability. It's been on 95% of my backpacking trips. Habagat Alpine - Someone gave me this giant backpack with primitive suspension. It does storage duty at home. Anyone else have a backpack fetish?
