Take advantage of the warm, inviting water of late summer with the Patagonia Men's R1 Lite Yulex Long John Wetsuit. It provides warmth and sun protection for your core and legs while still allowing total freedom of movement when paddling, and it's made in a sustainable manner that minimizes environmental impact. Unlike most petroleum-based neoprenes, Patagonia's Yulex rubber is derived from natural sources that have been certified by the Forest Stewardship Council and the Rainforest Alliance. Certification from these two organizations means that harvesting practices of Yulex rubber don't contribute to deforestation and are managed in a way that maintains the ecological functions and integrity of the forest, and that it enhances the long-term social and economic well-being of forest workers and the surrounding communities. Of course, none of this means anything if the quality isn't up to par, which is why it has also been developed and tested to meet Patagonia's rigorous standards for performance, durability, and warmth.
