Great for the colder month. 2.6 TOG sleep bag, your little one will feel like they're getting a giant, warm cuddle all night long. we love this style so much, owns 0.5 TOG, 1.0 TOG and 2.6TOG. Its absolutely the best. No need to fuss about diaper change during at nights. I put the baby inside the sack after she has fallen asleep, this wunderzip made it so easy to zip her in after baby is falling asleep. Sleep sack in perfect condition. Gently used and had always washed in cold cycle and line dry.
