I love these coats. I've been using them for the past 4 years. My son and I commuted an hour for work/ daycare for 3 years. The Transition coats were my goto for winter because of their design. Now that my son rides the bus for preschool, the Transition coat is perfect for the harness used on the bus.
These are quality coats. We used each size nearly every day in winter and they hold up. The zipper is sturdy. Not some of those cheap ones that don't align or with cheap and brittle fasteners. Even with many outdoor adventures and the roughness of a toddler, these coats hold up. No tears or stains. They've been washed many times. And the colors are great! I also love the tuck in hood.
The only drawback to the Transition coat is that it is not waterproof. It can withstand some rain for a short walk. Much more than that and it starts to absorb into the material.
I'm a big fan of the Transition coat. I've bought 4 so far and will continue to buy them until son grows out of them. It's a really quality coat even without the double zipper system. The safety system just makes it even more incredible.
