Wetsuit Recycling
At Circle One, we've gone one step further to combatting the on-going problem of end-of-life wetsuits ending up in landfill. As part of our commitment to sustainability, we operate a wetsuit recycling / re-purposing scheme in partnership with Barefoot Tech based in South Wales. Barefoot Tech take the usable material from end-of-life wetsuits and neoprene accessories and turn them into unique, fashionable accessories. Check out the Barefoot Tech website here.
