Washing Kris Holm pulse gloves

Pretty much as the title says, I have the pulse gloves and noticed during today’s ride they are getting a bit whiffy, but I don’t have the packaging anymore. Can anyone tell me how to wash them? Can they go in the machine or are they hand wash only?

Thanks.

I put mine in a mesh garment bag, then throw them into a load of towels. Then, I hang-dry them.

It has worked twice so far.
