The most incredibly compact swivel we've seen, the Rock Exotica NanoSwivel has a small upper eye and a lower eye just large enough to slip a carabiner into. (Careful, will not work with some larger-stock carabiners.) The NanoSwivel has the same high-strength stainless steel axle and sealed ball bearings as the larger Rock swivels and is rated for climbing (23 kN/5,175 lb) but weighs only 2oz. If you are looking for a smooth way to incorporate a swivel into your climbing setup, the NanoSwivel is for you.
