Nalu frames are moulded using a TR90 thermoplastic composite with NaluTek™ aircell technology giving them a sturdy yet lightweight feel. NaluTek™ aircells enable floatation without the need for unsightly additions, such as foam inserts. This allows your Nalu to be what they should be - good looking sunglasses, that's also float.

Nalutek™ Aircells:
