Here is a very practical baby carrier, the use and the settings are very simple and the opening on the front to install and remove the baby's great! The majority of settings is done on oneself before installing the child which is very appreciable. Little is installed, personally I have not tested the supine position but for what is ahead really good! For smaller one leg strap for added security. The weight is well distributed and the neutrality of fabric delights Dad! The material is very soft and the baby gate is not too steep as can some. It is used when 3k500 up 12kgs, once adjustments are provided to adjust to age.
