Fit was tiny but big even in the smallest size but fine cause he can use for multiple years. Incredibly soft and feels great to wear! Review: Great quality, had to size up though - The price for this set was so much better than any other wool set and it’s wonderful! It’s very comfortable and warm. I bought the smallest size for my 3year old and it’s a little long but still fits him just fine. Wool is usually tight anyways but I had to go up a size for my 6 year old, the size recommended was way too tight on him. ## Features - Midweight: Kids Merino Wool Base Layer Set package includes midweight kids wool base layer top and wool long johns for Kids 250 g/m² + Merino Wool Beanie ($24 Value).

Odor-resistant and soft enough for all-day use without irritation. **Q: How do I wash and dry it to keep it looking new ? Will it shrink or lose shape?** A: Machine wash cold max 30°C, delicate cycle, inside out. Lay flat to dry — tumble drying permanently damages merino fibers. Store clean and dry; keep merino in sealed bags to prevent moths. Wear 3–5 days between washes — merino resists odor naturally **Q: How do I choose the right size? Do the top and bottom fit the same?** A: Yes — top and bottom always come in the same size. Sizes are by age: 4-5, 6-7, 8-9, 10-12, and 13-14 years. If your child is tall for their age or has a longer torso, size up — bottoms run snug, so going larger ensures comfortable movement. **Q: Won't merino wool feel itchy? And what does 17.5 micron mean?** A: 17.5 micron superfine merino fibers are finer than human hair — too fine to feel itchy, even on sensitive skin. Standard wool (25+ microns) causes irritation; this doesn't. OEKO-TEX certified, tested against 100+ harmful substances. **Q: Where does the merino wool sourced from and is this product certified?** A: Our products are made from Australian merino wool, RWS certified — independent farm audit confirming animal welfare and land management standards. Every component tested against 100+ harmful substances under OEKO-TEX Standard 100. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome *by J***N on February 18, 2026* Bought these for my son and man he said he was realy warm even on an extremely cold day. Fit was tiny but big even in the smallest size but fine cause he can use for multiple years. Incredibly soft and feels great to wear! ### ⭐⭐⭐⭐⭐ Great quality, had to size up though *by J***L on October 18, 2025* The price for this set was so much better than any other wool set and it’s wonderful! It’s very comfortable and warm. I bought the smallest size for my 3year old and it’s a little long but still fits him just fine. Wool is usually tight anyways but I had to go up a size for my 6 year old, the size recommended was way too tight on him. ### ⭐⭐⭐⭐⭐ Soft and warm *by D***B on April 17, 2025* I realize that some people pass these up because of the price. I also realize I could buy regular cotton thermals for a lot less money but nothing beats a good pair of thermals. When I take my kid hunting and ice fishing I want him to stay as warm as possible without sweating. Nothing is worse then hiking to a hunting spot and sitting down and getting cold because my kid or myself broke a sweat on the hike out because we had to many base layers on or base layers that were all wrong. I learned very fast that merino wool socks keep my feet dry and warm and the merino thermal underlayment was just as good and if I didn't cheap out and buy a mixed material I would find these things just as good for my son. He is 8 years old and these things are the best! We have went ice fishing and he never complained about being cold. We sat on an all day deer hunt and he didn't complain once about being cold. The material is lightweight but keeps him warm and dry. They fit him perfectly. I am very happy with the purchase! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/743919781-100-merino-wool-base-layer-kids-set-midweight-unisex-thermal](https://www.desertcart.hr/products/743919781-100-merino-wool-base-layer-kids-set-midweight-unisex-thermal) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-13*
