Thermal Merino Baby Long Johns

If your child is inbetween sizes then we would always recommend that you choose the next size up.

Children can often have growth spurts and grow a couple of centemeters. By purchasing a larger size you can be safely assured that your new PO.P purchase will last the desired amount of time and more.

If you are purchasing outerwear the ends of the sleeves should not be too short or hang down over your child’s fingers.

With trousers, the ends should not be too short; nor should your child tread on them when they walk. And the crotch should not hang down too low and prevent your child from running freely.

Our clothes tend to be a little longer than the normal "age" sizes that you may find from other retailers. That's why we recommend measuring the height of your child instead. PO.P clothes are desiged to ensure maximum use from a minimum of 3 children.

If your child is the exact same height as one of our sizings we would recommend going for that size. Polarn O. Pyret clothes are designed to last, with our clothes tending to be a little longer for that exact reason.

How should a jacket fit?

Ask your child to lift their arms straight up. The cuffs should still cover their wrists when they do. Always use the Velcro fastening at the cuffs to hold the sleeves in place: if you turn the sleeves up, the jacket will no longer be waterproof. You should be able to grasp a generous amount of material at the lower back to double-check that there’s room for Layers 1 & 2. The seasons are long and your child needs plenty of growing room.

How should trousers fit?

Your child should find it easy to take some big steps. The reflectors on the legs should be clearly visible. Your child should not be treading on the ends of the trousers when they walk. When your child kneels, the ends of the trousers should stay level with the top of their feet and there should be no tightness around the hips. The seasons are long and your child needs plenty of growing room.

How should an overall fit?

Your child should find it easy to take some big steps. The reflectors on the legs should be clearly visible. Your child should not be treading on the ends of the trousers when they walk. When your child kneels, the ends of the trousers should stay level with the top of their feet and there should be no tightness around the hips. Tugging the shoulders of an overall should not make it feel tight at the crotch. You should be able to grasp a generous amount of material at the lower back to double-check that there’s room for Layers 1 & 2. The seasons are long and your child needs plenty of growing room.

How should a hat fit?

A hat should not leave any marks on your child’s forehead and you should easily be able to slide two fingers under the edge. The hat should cover your child’s ears. If the hat starts sliding up, it’s too small. Our sizes are usually a good match to your child’s age.

How should gloves fit?

Your child’s fingertips should not be pressing against the gloves or their hands will be cold. Gloves should fit well so your child can easily move their hands. Remember that manufacturers have different size measurements for the gloves and mittens they make.

Which size should I buy before my baby is born?

While we can’t give a definite answer, we generally recommend that you buy a few items in Size 50, one or two in Size 44 and one or two in Size 56. If you keep the original tags on, any item that’s too small can be returned after your baby arrives (a full refund is available for 14 days). And any item that’s too big will fit your baby eventually. Here’s our list of the clothes you need for your new baby!

Which size should a windproof fleece pramsuit be?

Your baby needs enough room to wear 2-3 layers underneath. Our pramsuits give your baby plenty of growing room. You can fold over the sleeves and leg cuffs at first. When this is no longer possible, you can add mittens and booties so that your baby can get more wear out of the pramsuit. But a pramsuit is too small if it’s tight, or there are gaps at the legs or sleeves. Important! It is not safe for a baby to wear a thick or bulky pramsuit in their car seat – it creates too wide a gap between the baby’s body and the safety harness!

Which size hat should I choose?

A hat should not leave any marks on your baby’s forehead and you should easily be able to slide two fingers under the edge. The hat should cover your baby’s ears. If the hat starts sliding up, it’s too small. If you plan to buy a hat before your baby is born, our sizes are usually a good match to a baby’s age.

Which size booties should I choose?

We usually recommend choosing the smallest size at first. But if your baby’s toes are pressing against the front of the booties, they are too small. If booties tend to fall off in the pram, our mitten clips can help to keep them in place!

Which size socks should I choose?

Socks should stay up, the heel should remain in place and the fabric should not be too tight. A very young baby’s socks will rarely need washing, so two pairs in Size 10-12 and two in Size 13-15 are a good start if you’re buying before your baby is born. Our soft ribbed socks for newborns stay on your baby’s feet and are hugely popular!

Which size should I choose for my baby’s first shoes?

As soon as your child starts to walk, it’s time for their first shoes. Choose lightweight, flat shoes with smooth soles, as too much traction will make walking difficult. Choose a higher style shoe that stays on your child’s foot and gives better balance. The shoes should also have good breathability because young children perspire a lot.

Which size swimwear items should my child have?

Our swimwear sizes are the same as our ordinary clothes. Simply measure your child’s height to find the right size for them. But keep in mind that children tend to have growth spurts, so always use an up-to-date measurement. Your child’s height in centimetres tells you which clothing size you need. We specify ages next to each size as a rough guide if it’s not possible to measure their height. But height is a better guide than age when finding the right size, as all children are different!

How should UV clothes fit?

It doesn’t matter if UV clothes are close or loose fitting – as long as they cover the required parts of your child’s body, they will provide effective UV protection. So choose the size that feels most comfortable.

How tightly should a swim nappy/swim shorts fit?

If your child is wearing swim shorts with a drawstring waist, you can fasten it firmly enough to suit your child. Then the actual shorts does not need to fit too tightly. Fasten it firmly enough so no poo can leak from the shorts, but no tighter than that. The drawstring may leave slight marks on your child’s body, but there should be no redness on their legs or tummy.
