The OneKid jacket has been a game changer for us! I know that new car seat regulations make it so children can't wear big winter jackets in the car. My husband and I followed that guideline when it came to bigger, puffier winter jackets. However, we didn't want our son to be too cold while we traveled so we always put him in a lighter jacket. However, even a lighter jacket would bunch up and technically still wasn't safe for him to wear. I have seen parents who put their children in the car and bring puffy winter jackets with them to put on their child when they get their destination. As a busy mom, I didn't want the hassle of having to bring a jacket that I would have to put on and take off every time we went to and from our vehicle. He's still too little to do this on his own and it would make simple errands that much more tedious for everyone involved, not mention make the trips that much longer because of all the clothing changes that would have to take place. I kept seeing the advertisements for these jackets and figured why not try it. After discussing with my husband we bit the bullet and bought one. We went with a size or 2 larger so my son would be able to grow into it, mainly because the jackets are expensive and we didn't want to have to buy a new one each season. After using this jacket for a few weeks, I wish I had gotten the most expensive jacket, since there were a few more features than the current one we have! They are 100% worth every penny, and I will be recommending this product to any parent who is looking to keep their child warm during the winter months. I love that my son can keep warm safely in the car, and I don't have to bring an extra jacket just to put on him once we get to our destination. (I do want to add, that we do put the heat on while in our car, however, if we travel with my husband he gets hot quickly and we usually need to turn the heat down to a more tolerable temperature. This is why having a warmer jacket while traveling was definitely something we wanted to invest in.) Overall, this product is a saving grace and I wish we had invested in this sooner! Do yourself a favor and purchase one if you are even considering making the purchase.
