LYNX is our thinnest all-in-one for babies. This garment is made of 100% polyester-50% recycled and has a soft brushed inner. It can be difficult to make the right choice when it comes to fleece fabric because its quality and weight can vary widely. It is important to check whether or not the fleece is flame-retardant. All fleece from Isbjörn is flame-retardant. Another important factor for comfort is to choose a fleece that allows excess heat to escape. Otherwise, the wearer can quickly become uncomfortable and sticky if the weather turns warm and humid, which is particularly important where babies are concerned, as they cannot yet regulate their body temperature. A high-quality fleece fabric guarantees a high level of comfort. We have made no compromises when choosing materials for our LYNX microfleece suit. This suit has a long zipper that runs from the neck down one of the legs and a zipper garage for added comfort. Soft arm and ankle cuffs ensure that sleeves and legs do not ride up during active play.
