I am a small frame person and the Rangs Jr fit and worked for me even though I am an adult. They provide less flotation then the Rangs SR since they are smaller with less flotation material. They were a perfect match for me....much less flotation then a pull buoy but helped just enough to improve your body position while making you work hard!

These Rang floats work very well for body position and form.  However they don''t work well at all with flip turns in a pool.  Even with Jammer shorts for males, you can''t get them tight enough to last more than a few flips without them sliding down to your knees.  On skin only for females, I think they''d be almost useless.  However, if you want to use them for open water swimming like Triathlons, I think they work quite well.

This is the best product I've seen from Finis since the Front Mounted Snorkel!!

Bicycle kicks . . . gone
