Lightweight Sleep Bag | Mountains

(7 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

    Lightweight and breathable

    Posted by Tobi Marie on 21st Jul 2020

    I bought this sleep bag and I love it so much! I bought the lightweight one since it is summer time and it can get pretty hot in our house since we do not have AC. There is still room to layer up if need be. I am super happy with my purchase. Will probably buy another one soon.

    I prefer swaddles

    The sleep sack is definitely too long. I expected a tighter fit like a swaddle.

    We live in Southern California and I find the lightweight perfect for our temperatures. Good quality and awesome prints.

    Eco and Fair

    I love buying from organic and fair brands like Little Fishkopp. With the GOTS certification you know what you are buying.

    This was my first sleep sack purchase. I did not realize how well they work. My son (4 months) sleeps so much better now and I get more sleep!!!

    Really nice fabric

    I am obsessed with their organic jersey cotton. So soft like your favorite T-Shirt. And my kids both sleep great in these.
