What is this product made from?

Our Kosi kids hoodie has been made in the UK from beautifully soft merino wool.

What is this product made for?

The Kosi can be worn as a mid layer over other clothing, or it can be worn directly against the skin as a children’s base layer.

What makes the Kosi hoodie different from other hoodies on the market?

It is versatile and can be worn as a thermal base layer or as a mid layer with a layer underneath. My design means the top is totally seamless for maximum comfort and happier children. There is no neck label either meaning no itchy annoying labels in the neck and no moaning about itchy, uncomfortable clothing. This also makes our kosi hoodie suitable for some children with sensory issues who may struggle with seams and labels in clothing.

My clothing is designed for kids to look great & feel great and to help keep them warm and comfortable in nature. I have spent a long time developing my products to ensure you can stop worrying about them when they are outdoors, especially when you aren’t with them and can’t keep checking is they are too hot or too cold. I  want to take the worry out of spending time outdoors with your kids so you can just enjoy your time together and play more.

Why should I buy the Kosi Hoodie

  • From a parent’s point of view this kids hoodie is amazing. It’s lightweight and packs down small so it doesn’t take up too much room in a rucksack.
  • Being merino it helps to regulate temperature and it retains its warmth even when wet. This makes it perfect for outdoor activities.
  • Its the perfect base layer or additional top to ensure your kids are warm and comfortable whether hiking in the mountains or at ski school.
  • Its been designed for kids with parents in mind to take away some of the worry when spending prolonged periods outdoors. 
  • The fabric in naturally crease resistant which means the fabric hangs really nicely on the body
  • It looks great on.
  • It feels great against the skin

How do I wash it?

The Kosi hooide is easy to care for and can be washed in the machine on a wool wash no higher than 30 degrees wash. We always recommend a wool or handwash cycle to ensure your product lasts a lifetime. 

Don’t use fabric conditioner. It won’t alter the look of the product but it will clog the fibres and stop it working so well as a thermal layer.

Never tumble dry a merino wool product.

They are naturally crease resistant and easy to care for.

How do I choose the right size?

The Kosi Hoodie comes in ages sizes. The sizes do come up small as standard so I recommend you buy the size up to ensure the longest amount of wear. Please email or call 07817 104595 for further advice on selecting the right size for your child.

What about when it’s outgrown?

I want my products to be worn, loved and handed on. Don’t forget that once one of my merino wool products has been outgrown and you can’t find a new home then simply return them to me for recycling and I will give you 20% off your next purchase via my RECYCLE SCHEME

What if I don’t like it or it doesn’t fit?

I offer a 100% guarantee. If you aren’t completely satisfied within 14 days simply return to me with the bags & tags in saleable condition and I will exchange or refund your purchase.

The sizing for our childrens base layer comes up large as standard, children vary greatly in size so we have allowed additional room to compensate. Please refer to our sizing chart for full sizing details for our children's base layer and contact us if you have any queries on sizing. Please Note the following information regarding our kids base layers. Our base layers are intentionally longer in the body and will fall below the hips. This is to allow for the product to be tucked in when worn as a base layer. It is also to provide extra warmth and comfort. This also makes the product perfect for taller kids.

Merino Wool Care Instructions & Golden Rules:

Our Merino wool care instructions for our Lukla Baselayer are as follows:
  • Machine wash on a delicate or wool wash cycle, no higher than 30 degrees.
  • Never tumble dry.
  • Don’t use fabric conditioner.
  • Don’t use bleach.

Extending your garments life:

  • Even better than a delicate or wool wash is to handwash your merino.
  • Make sure you either line dry or lay your garment flat after gently reshaping, do not wring dry. Merino is quick drying so should dry overnight in a warm room.
  • Merino doesn’t crease easily but if you do need to iron your garment then use a cool iron.
  • Use a mild, non-biological detergent where possible.
  • Be careful with zips/jewellery etc as wool can snag causing holes.
  • As a wool product, you should expect some pilling with time, you can reduce the amount of pilling by using the gentle wool/hand wash cycle on your machine.
  • If it’s cared for properly your garment shouldn’t show signs of shrinkage but items can shrink when exposed to high temperatures so never tumble dry or wash on a cycle higher than 30 degrees, the lower the better.

It is important that you follow our merino wool care instructions to extend the products life and to avoid damage.

Failure to follow the merino wool care instructions above may lead to your product shrinking. It is particularly important to wash your Lukla kids baselayer on a cool handwash cycle or delicate cycle as high temperatures can cause merino to shrink and felt. We are unable to exchange products that have been damaged due to incorrect washing. Please CONTACT US if you have any additional questions with regards to our merino wool care instructions.
