发明名称 Flotation device
摘要 A flotation device including an elongated body portion with a substantially rectangular shape capable of fitting around a user's midsection. This elongated body portion is made of buoyant material and has an exterior shell made of substantially semi-elastic material. The semi-elastic material can be extended to form a tighter fit around the user's midsection. The flotation device of the present invention also includes at least two adjustable side straps attached to the elongated body portion. Each adjustable strap extends in a longitudinal direction and along the major dimension of the elongated body portion. These adjustable side straps can be adjusted for a tighter or looser fit around the midsection. The flotation device also features a two-part adjustable bottom strap having a first end attached to a front section of the elongated body portion, and having a second end attached to a back section of the elongated body portion. The first end and the second end can then be fastened through the user's legs to engage corresponding male and female buckles.
