Bobber Hat Float
- Floats most hats
- Low profile comfortable fit
- Easy attachment/removal
- Closed cell foam with high buoyancy
This simple gizmo does what it is supposed to. The velcro has very strong grip, and it seems to be glued very strongly to the float, so it should be possible to reuse. And well, this is not limited to hats, but whatever light-weight thing with a strap you have.
The slot for the strap is 2 cm wide, by the way.
