FABRIC HORSE Lock Holster, $10, www.fabrichorse.com
Perhaps the simplest and greenest product we’ll ever review. Essentially reinforced loops made from recycled seat-belts that slide onto your own belt to hold a D-lock — genius. Slotted between the most suitable belt-loops on your jeans the lock won’t flap about or dig in (like it does when just slipped behind a belt). Our sample fitted half-a-dozen common lock sizes from the main brands, but the team will happily make one to any size if they don’t already stock it (allow a couple of weeks). Only available direct from the States at the moment. Also available is a full holster belt for $26.50.
