Used in swimming pool to increase strength.  Coating on weights does not allow weights to pick up water and weigh even move.  Both weights are made exactly the same.  That means that one of the sets of buckles are on the outside that can''t easily be reached.  If one set of straps wer put on the other way then both sets of buckles woud be on the inside.  I have to turn one set of weight over to accomplish this.

Kinda bulky and hard to put on.

He loves them - they give him a better work out

These are great!  I do a lot  of aqua therapy and these are super in the pool!

I have small ankles and I have to tighten them to the limit, but once get into the water  there is no discomfort  

I bought these to take to my swim class because the class only has one set and it is hard to snag them.  These weights are very comfortable to wear and easy to adjust.  When I ordered them it was difficult to figure out from the description if they were a total of 5lbs for two weights or 5lbs each.  I ordered them knowing they might be the latter and did note a review that remarked they are heavy.  They really are too heavy to carry to class every time along with the other things I take so I am thinking of marking them with my name and leaving them there.  Also, the cover is comfortable but not waterproof and they take a loooonnng time to dry out.  They are heavier than the ones I was using in class but I was still able to wear them until we did an abdominal exercise we call "killer abs."  In that case they put too much strain on my back and I took them off.  It will be cumbersome to take them off and put them back on in the water if that exercise is done early in the class.  I might go ahead and order the 2lb each weights so I have options....  All in all I am very happy with these weights.  They are hard to find in a local store and when I found some the price was high.
