Some SUP jackets are basically half a wetsuit, while others are more like a windbreaker....and this one is a perfect match up between the two! Unbrushed polypropylene material keeps your torso warm, while bamboo/poly mesh sleeves allow for lots of movement and breathability. A front zip keeps it simple to get in and out of so it's no muss, no fuss, just fun on your board. Once again, all is as it should be. Imported.
