## Questions & Answers

**Q: Is this only for winter, or can kids wear it year-round?**
A: Merino thermoregulates in both directions — warm from 40°F down to 5°F (-15°C) for skiing and ice skating, yet breathable enough for school, cycling, spring hikes and everyday wear. 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 New Zealand 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.
