Lightweight Sleep Bag | Superheroes

(8 Reviews) Write a Review

Our organic sleep bags help little ones sleep safe and sound and give parents peace of mind. They are a modern solution to the problem posed by loose blankets that can cover a baby’s face and interfere with breathing. Because little ones can’t kick them off, sleep bags provide warmth and comfort all night. They make a great bedtime routine for both babies and toddlers. Just zip up the sleep bag, and your child knows it’s time to sleep.

These lightweight sleep bags are 1.0 tog, which is good for room temperatures of 69-74°F (21-23°C). Also available in our standard style (2.5 tog). For more information, see our tog chart

    We love this!

    My husband and I both are not good at swaddling so we got this. So much easier and our baby loves it.

    Safe sleep

    Posted by Gina T on 22nd Jul 2020

    My baby is an adventurer and loves to try to get out of her crib. Our doctor recommended a sleep sack over a swaddle and on my search Little Fishkopp popped up. I appreciate a small business that makes quality products for a fair price. My son now sleeps safe and sound. It really gives me peace of mind. Thank you.

    Recommend as a shower gift

    Posted by Ariana C on 12th Jul 2020

    I bought this as a gift for a friend when her son was born. The colors and the design are great and gender neutral. I definitely would recommend it as a shower gift or for your own little one. So much attention to detail and high quality materials.

    Our favorite sleep sack so far and we have tried a few. We love the breathable organic cotton and the reverse zipper. Makes diaper changes a lot easier. Worth the price!

    Great Quality

    Posted by Anita P on 11th Apr 2020

    This sleep bag is very well made. The organic fabric is very nice. I like sleep bags, but unfortunately my son did not. That is why I only gave it three stars. It did not work for us.
