The LENZINGTM FR viscose fibre, which is sustainable and innovative, is used in the construction of Alpinestars TECH ZX Series boxers. It offers superior heat transfer resistance and flame resistance. Extremely thin and light, with a wonderfully silky texture, these Formula 1-derived undergarments provide significantly more comfort when worn under the required layers of knickers. Strictly compliant with FIA 8856-2018 homologation requirements for undergarments.
