  • The bamboo lining is so soft and feels lovely next to baby’s skin. The whole sleeping bag is well made and light, so even with a heavier rating does not swamp her. Detachable sleeves, great bonus. Anna
  • I was delighted to see the SleepSac not only has sleeves but they are also detachable. Hayley M
  • The PurFlo sleepsacs are awesome, they are warm and snuggly and have fantastic arms which can be zipped on when the weather turns colder. I'm now using the PurFlo sleepsac with my third child and it is still in perfect condition, it washes beautifully and is easy to put on and take off. Emma Sinfield
  • They are the only sleeping bags I'll buy since using them for my first baby. Absolutely fantastic! .. Abby M
  • For the past year my son has slept in a Purflo SleepSac. They are absolutely fantastic! From the first night he slept in it, his eczema improved dramatically particularly on his face. Dawn N.
  • I've started using my sleep sac for the last few nights. My little boy is 5 weeks old. He is an active sleeper and kicks the covers off, getting a bit cold at night. We decided to try the sleep sac- He loves it!! He has slept between 6 and 7 hours through the night each time we have used it. Brilliant! You are also the only company I found that make them 0-3 months. The others seem too big at the moment. My hubby is now asking if they are available in adult sizes!! Thank you purflo. From Amy and baby Charlie x
Q:What weight can babies go in to SleepSacs?
A:All PurFlo SleepSacs comply with the British Standard BS8510:2009 for Safety of Children's Sleeping Bags. This British Standard specifies requirements for the safety of sleep bags for the use of children with a minimum weight of 4 kg
Q:What clothing should my baby wear underneath the SleepSac?
A:It does depend a little bit on room temperature, but we would normally recommend a short sleeved bodysuit if you have the SleepSac sleeves attached and a long sleeved bodysuit if you have taken the SleepSac sleeves off.
