The O'Neill Women's Psycho Tech 4/3+ Chest Zip Wetsuit is the perfect balance of warmth and flexibility and we love that 0.5mm of neoprene was added to this suit for extra warmth. Made of buttery soft TechnoButter 3 neoprene with a TB3 Air-Firewall lining for toasty warmth and quick drying abilities the Pyscho Tech was constructed with minimal seams to keep you loose and free in a stitchless construction. This suit is definitely worth the investment.
