this is a snug fit, which is perfect for training as it feels more like part of the body rather than another thing to overcome. our grandkids bobbed around like barrels until 20-24 mos old, when they start to manuver somewhat. the difference between a life jacket (which has a mind of it''s own) and a Konfidence jacket is immeasurable. a life jacket is more fun when it''s off and a Konfidence jacket is more fun when on.

This is our second jacket for our 4 year old and she loves it!  I used to teach swimming years ago to toddlers and this jackets provides the right support, freedom for kids to enjoy the water and build their own confidence while remaining safe.

lovely fit
good mobility around the arms
easy to wear

Ordered size 3-4  for my 3.5 yo, who is of average size. couldn''t even bring it together and zip it on her. Then, i ordered the 5-6 size, that one was right on; however while wet it felt a little loose, that wouldn''t be a problem if there was some tighten belt on the buttom portion. Overall, it looks good, and serves its purpose.

Fits as we expected and helping our 7 year old learn to be more confident in the water while keeping him safe. Thanks!

too tight on pudgy grand-daughter, has NO crotch strap,
