Skemer's review of the Accessory Strap:
With buckles of a lightweight anodised aluminum alloy, the Sea to Summit Accessory 10mm wide 2m long straps will be one of the most versatile items in your gear bag. A few of their uses include strapping gear to roof racks, lashing dry bags together and attaching gear to your pack.
