Swim float |
摘要 |
A swim float constructed of a plurality of hinged sections. Core blocks are hingedly interconnected by upper and lower flexible layers. Sidewalls of adjacent flexible layers are bevelled so that the skin of a user will not be pinched therebetween. The hinges alternatingly are formed by the upper and lower flexible layers so that the swim float flexes and follows the contour of waves.
