The sail is said to offer 99% UV protection. I can not control it, but wonder what sun protection factor (UPF) corresponds to the sail? It seems to have been not been tested according to UV Standard 801, otherwise it would certainly appear on the packaging - eventually would be a good advertisement. So I can only on the testimony of the provider trust confirm the protection without additional award or seal.
The sail itself is very easy to assemble. The wide part is drawn with a rubber over the head part of the baby carriage and secured with the strings on the handlebar. Since the problems already go off: The sail can not really even get halfway to tension because one otherwise the broad "headboard" accommodates. Thus, the member always depends by and the two bands on the handlebars slipping back and forth. Clear fulfilled the sail as well as its purpose, but it looks simply from totally stupid and you have to constantly rumziehen to the part and zoppeln.
I'm still not sure if I bring the part back or Remodeling with a little creativity and a string, so I can fix the headboard better.
Conclusion: Meets though (hopefully - see above!) Its purpose, but the handling is really poor! Limited buy recommendation!
