25 years of baby sleep expertise, woven into every thread
Not all sleep bags are created equal, and we’ve seen that first-hand. For over 25 years, our team has been part of the baby sleep bag story. We helped develop some of the very first sleep bags in the UK, and have spent the decades since refining the details that matter most — the fit, the fabrics, and the safety of every stitch. When you choose a Folk & Thread sleep bag, you’re choosing decades of care and expertise woven into every thread, designed to help your baby sleep safely and comfortably night after night.

The Better
Sleep Project
Through the Better Sleep Project, every Folk & Thread purchase helps provide safer sleep for little ones in need. In our first year, we worked in partnership with the Lullaby Trust to support their Bedtime Bundles project, donating 1,200 products to families living in temporary accommodation - and we’re just getting started.

The sleeping bag has been great. It fits well. Is easy to get on and off. The zip design is good as you can change a nappy without having to take the baby fully out of the sleeping bag
Lucinda
Liked the position of the zip – didn’t get in the way of breastfeeding, loads of room for feeding and washed really well
Emma
Sleeping bag is fantastic and the optional reduced length was a great idea
Aliyah
Washed and dried over and over and still looks like new.I like you don’t have to unzip fully so stays warm during nappy changes.
Luci
Quality was good- thick but not heavy, cosy and soft
