OMM says:
The OMM Swift Arm Warmers are a new product designed to add that extra bit of warmth when a top layer jacket or smock is too much. They are made from 2 way stretch material with flat lock seams thumb loops and reflective logo. This all makes the OMM Swift Arm Warmers a great choice for races.
These OMM Swift Arm Warmers are ideal for adding a bit of versatile insulation to your minimalist running kit. Stash these in a pocket and if you're going over an exposed fell and the wind is picking up, stick them on and you've added just enough protection to get through comfortably.
