This Week’s Pick of the Week is the Black Diamond Speed Zip 33. Perfect if you’re looking for a lightweight, stripped down climbing pack. br br The Speed Zip is an update on previous models, with re-designed shoulder straps and a thermoformed back panel. With the zip model, the lid system has been changed to incorporate a clamshell opening system. This reduces the amount of bulk in the lid, and makes packing your kit away a quick and easy job.br br We’re selling this 33 litre backpack at the EpicTV Shop for just €124.90 down from €140.
