Hooks and clips for hanging gear.
The Lulabop Heroclip is a clever rotating, folding hook carabiner for hanging your gear anywhere. Made from aircraft-grade aluminium, composite, and steel, it holds up to 22kg, though it isn't rated for climbing, and weighs just 29g.
Cubby: Coat-hook + Storage Unit was a Kickstarter project funded on 6th May 2012, raising US$53,707 against a US$29,000 goal. Backers could get a Cubby for US$19, plus US$8 shipping. I didn't back it, as I only learned of it.
