The colors are bright and brilliant and that is so desired, so that our daughter swim in the lake is clearly visible because in some ride indeed motorboats and is generally highly visible a safety feature.
We already had the same model in a smaller size and were also happy with it.
The seams are of good quality, it dissolves no not with intensive use (at least 2x / week) and the color and the fabric to resist the chlorinated pool water (Winter) properly.
The sizes are for our sense of rather scarce, ie taking range, some larger.
From us a buy recommendation - not cheap, but good value, ie its good value in our view.
