These Swany mitts are New-Old-Stock. As stated on the tags: The Triplex insulation system works with your body by using three popular insulatons that are fitted to each individual hand zone. The mitts also have the Dryfinger II insert which is a monolithic insert made of advanced polymers. The inserts allow moisture (not just vapors) to pass from the inside out. The molecular structure makes the insert 100% waterproof whilst allowing superior breathability. Note: All warranties are null and void.
