As someone in the medical field, I love the accessibility options. As someone with autism, I appreciate the inclusion of not only having your son help you, but also with your products striving to adapt to a sometimes wide, and sometimes very specific area of needs/desires. My wife and I got the this one (light blue) and she got one in a similar style but light purple and while similar, this review will be primarily focused on the blue pajamas as the review is being posted on that page.
My first impressions have been very positive. The pajamas are easy to put on, easy to remove and are comfortable and encompassing without being overwhelming. The hand/foot covers work well overall and are very easy to apply/remove if and as desired. The easy access opening for restroom use is also works easily and as advertised, being pretty seamless. This one we bought has buttons on the front and I was surprised at how comfortable it was. while that may seem silly to some, that kind of thing can be a deal breaker for others. I can be described as overly specific or sensitive to how things fit/feel, so to find pajamas, let alone a full body set that I can wear comfortably is what impresses me the most.
While I don't have any cons for this product, I do think there are things to keep in mind. Temperature seems to hit that sweet spot but colder weather may require additional coverage (or a warmer set). These adapt to a variety of builds, but if you broader shoulders, it may require some readjusting at times if you are at all sensitive around the chest/throat area.
Lastly, I wanted to say how overall impressed I am by the overall customer experience. The shopping is fast, and has tracking. I am also impressed by the brief, yet detailed short videos produced explaining the differences in their products (like the essential vs snap down for instance). This is a quality product and definitely think it's worth a look for people who want a set of cozy pajamas, or who have medical or special needs.
Ps - Sorry if this is the wrong place for this, but we love the designs you guys have made, in particular, the "Glow-A-Saurus". If you ever make that design in adult snap downs, I don't think we could buy them fast enough!
