New Pant Style Released!

For the ultimate layer, check out our new grow-with-me merino wool Ultra Cozy Jogger Pant. Made in a merino wool sweatshirt fleece, these pants are designed as a mid layer to replace your polyester fleece once and for all! They feature a looser fit through the hips and upper leg, gusset for maximum mobility, reinforced knees, a grow-with-me design, POCKETS, and an incredibly soft and cozy all natural wool fleece fabric. Plus, they are machine washable! Mic-drop.

We have been working for a year to come up with a good mid-layer option for folks who want a functional alternative to poly fleece. These joggers (and the matching hoodie) are the results of a lot of planning and testing! We hope you love them. They have already become a favorite in our house and a great addition to our kid adventure kit.

Ultra Cozy Merino Jogger Pant


How do they "grow"?

Our designs have a little extra room in all the right places.

  • Extra long cuffs, made from a lighter weight fabric roll up without extra bulk.
  • Soft wide waistbands fold over and then expand again as kids grow.
  • Raglan sleeve design means no shoulder seams for more flexibility in fit through the shoulders and chest.

We have tested this sizing for years and found that it really works!

How do I care for them?

Our wools are machine washable and can be dried in the dryer!

  • Machine Wash Cold
  • Tumble Dry Low
  • Use gentle biodegradable laundry soap and stain remover as needed

Made to Last.

We don't want you to buy more. We want you to buy one quality set you will use, and wear them everyday.

What is Sustainable Fashion?

Better Materials, Less Waste.

At Wildhaven, we call ourselves a "sustainable kids clothing brand", but what does that mean? To us, that means using natural biodegradable materials like merino wool and sourcing from ethical factories with the highest eco-standards. It also means making practical durable kids clothes that last, not just for one season, but for years.

We strive to make clothes that have a minimal impact on our earth. That is what being a "sustainable" clothing brand means to us.

Alexandra Burke
Such a great mid layer

We already had a few sets of base layers but my littlest loves to be extra cozy. These were perfect to use an everyday layer. The material is heavy enough I don't worry about her wearing it out even with really rough play and the ankle design is slim enough to easily fit inside a pair of boots. The pockets felt a little silly and bulky on such a small size (2T on an 18M old) but she really loves them. Definitely going to look at getting larger sizes when the time comes!
