An adult sized inflatable swim vest that gives you a very pleasant hug when inflated! Includes a headrest which is a rare thing to see on adult sized vests. The main chamber valve is also located in a convenient location to inflate it yourself while wearing. And there is an automatic version available too, if you're not afraid of pulling the string and having the thing pop up with a nice loud whoosh! The yellow version is made out of flexible glossy TPU, and the black version is made out of super thin black glossy PVC — looking almost like latex when wet! Comes in a single size that's roughly an M~L on the scale of most commercially available vests. (I'm 6'4" tall and about 50cm wide, and at full inflation it was just tight enough to make breathing a tiny bit hard -admin) [WARNING] - NOT A LIFESAVING DEVICE. DO NOT USE ON WATER. For decoration/cosplay use only. - Use of the automatic inflation function is AT YOUR OWN RISK. Do not use automatic inflation on an already inflated vest, or it may pop and even violently explode (Check out that one automatic ring video we have in stock to see how that happens ;-) - Do not overinflate, especially the black PVC version — the material is pretty thin. Probably best to inflate after wearing. - Do not inflate to the point wearing the vest is causing trouble moving or breathing, and have someone check in on you every now and then. Take necessary precautions to prevent suffocation and accidents. We cannot be held responsible for anything that might happen as a result of use of this product.
