Ergo, Ergodynamic PaddleWear by PaddleAir (X-Large) Creates a stronger and air-adjustable paddling position for surfers; provides for more power-per-stroke so you can paddle stronger and surf longer! Relieves repetitive stress injury (RSI) and elevates the chest to ease neck, shoulder and lower-back strain while paddling. The Neoprene front acts as a rash guard for comfort to ribcage and cushion surfer bumps. The Lycra back abd sleeves offer U.V. 50+ protection and act as a windshirt. The interior of the Ergo is smooth and comfortable on the skin and can be worn alone or over/under a wetsuit.
