The MV5601 SAR Vest is strength-tested to 100mph meaning it has been designed, tested and approved to hold up to rigorous activities. The high neoprene-lined collar provides impact protection by minimizing neck mobility and the large 3-belt adjustment system creates a secure fit. Large cutaway armholes for maximum range of motion, SOLAS reflective tape for high visibility, large front cargo pockets and multi-purpose fast tab radio clip, make this durable and comfortable PFD a functional part of your personal protective equipment.
