Sustainability meets stretchable performance in the Billabong Furnace Natural B-Lock Jacket. 100% neoprene-free, the natural rubber 1mm wetsuit jacket made from Yulex delivers all the warmth and flexibility you find in a premium wetsuit without the toxic chemicals. The eco and performance-minded wetsuit top is backed by Recycler Airlite Stretch jersey lining made from 100% recycled PET featuring CiCLO® Technology, which helps close the loop and reduce plastic pollution in our oceans and landfills. Limitless stretch paves the way for a zipperless entry system for a smooth feel and extra flexibility. Sealed with water-based glues, the Furnace Natural Jacket is quite simply the best, most sustainable suit you’ll wear.
