ION Muse Neo Zip Top 1.5 DL (FL) WomenThe ION NEO TOPS are a must have for every watersports nut hitting the sea or surf in milder climates. Although mainly used in warmer waters to keep the sun and wind off your skin, they can also be used as a second layer underneath the wetsuit. Thanks to the plush, wool like Hot_Stuff 2. 0 lining, these tops have a luxurious texture that feels great, even on bare skin. In spots without thermo lining, super soft Silk_Stuff increases comfort to the max.
