Defy is a limited edition and as such will sell out. When sizes are no longer listed as an option it is due to that size being sold out globally and we are no longer able to get a restock.
We recommend hand washing your elbow sleeves with water or a mild detergent (or a specialist neoprene/wetsuit detergent), then allow the sleeves to air dry standing up.
The spin cycle of a washing machine can damage the sleeve, as the elbow sleeves become quite bulky when wet and can potentially get caught up or damaged by wringing. High heat from a washing machine or a dryer will degrade the rubber in the sleeves (potentially causing shrinkage or brittleness).
