Defected

Pretty sure I received a defected product. The zippers should be attached on each side, but I have two zippers of the three that are not attached and I can’t hook it back to make it work.

Better than the competition

Great sleep sack. Very warm and feels premium. Whilst I’ve given it 5 starts, the only thing I would add to it non-slip grip on the feet. But that’s very minor and should distract from a fantastic product.

Stiching undoing..

This is the second suit I’ve bought in a month and the stitching is coming undone. I’m so sad as I really love ergo pouches..

The best SleepOnesies

We live in the Yarra Valley and nights get very cold. My daughter sleeps with two layers plus the 3.5TOG and nothing else. Great quality. I highly recommend.

Wow

Really love all of your products. The quality is really strong and its so warm. Such a life saver in winter. I’d buy one of everything if I could!

Very comfy and safe

This sleep onsie is the perfect option for little ones who constantly kick the covers off even on freezing cold nights and prefer to have their feet out. My little girl can move around in it easily before bed and it keeps her so warm, she has worn it with nothing underneath and worn it with pyjamas underneath and both are comfortable and not too tight or restricting.
