Used this in December in NYC for a trip and it was THE BEST! My daughter was so warm and cozy and it was so easy to put in the stroller. We have the Nuna Mixx and it fit perfectly.

Our family loves this Footmuff. It’s much nicer than the generic Amazon ones we’ve tried and is also easier and more functional than the Nuna brand one we used to use. We are a big Nuna stroller family and currently have the Mixx Next and Trvl. The footmuff’s seatbelt openings line up perfectly for both of them making the footmuff fit great in both strollers. We love how the zipper works and holds the front in place. On colder walks, we zip it almost all the way, but on more mild days we unzip halfway so he isn’t so hot. It's honestly a great design, and our boy loves it. The zip out extension will also be great for when he grows some more and we need a little extra room. Overall, very happy with this purchase. Definitely a must buy for Nuna parents living in cooler climates
