The NYO women's buoyancy vest is made from the newly developed NeoLite 3D material. This material has a similar look and properties to neoprene but is significantly lighter, more breathable, and feels pleasantly soft. The flexible PVC foam provides ample buoyancy and all-around impact protection. Large armholes ensure enhanced freedom of movement while stand-up paddling, wakeboarding, or jet skiing. Thanks to the two sturdy straps with snap buckles, you can perfectly adjust the flotation aid to your body, ensuring nothing slips. Simply secure the straps with the belt clips to prevent them from dangling. Choose the appropriate size based on your chest circumference: Sizes (Chest circumference, Body weight): XS (76-83 cm, 30-50 kg), S (83-91 cm, 40-60 kg), M (91-99 cm, 50-70 kg), and L (99-106 cm, 60-80 kg).
