Smartwool Ski

Frequently Asked Questions

• What makes Smartwool’s NTS (Next‑To‑Skin) base layers good for skiing?

  Smartwool’s NTS base layers use high‑quality Merino wool or Merino blends with zonal knitting and strategic mesh zones to manage moisture and temperature right next to the skin. Flatlock seams and articulated fits reduce chafing under ski layers while the merino fiber provides natural odor resistance and next‑to‑skin comfort.
• How should I choose between Merino 150 (lightweight) and Merino 250 (midweight) for ski use?

  Choose Merino 150 (≈150 g/m) for high‑intensity days like uphill tours, spring skiing, or when you tend to overheat, because it’s lighter and more breathable. Pick Merino 250 (≈250 g/m) for cold, low‑activity days or resort skiing where extra insulation matters; it traps more warmth without sacrificing moisture management.
• How do Smartwool Thermal Mid‑Layers (TML) work with NTS base layers for layering on the mountain?

  TML pieces are designed to be worn over an NTS base layer to add insulating loft while preserving breathability; combine an NTS base (light or midweight) with a TML when temps drop or you anticipate pauses in activity. The system is intended so the NTS handles moisture next to skin and the TML provides core warmth, letting you fine‑tune layers by activity level and temperature.
• What should I look for in Smartwool ski socks and materials for different terrain and boots?

  Look for ski‑specific socks that blend Merino wool with nylon and polyurethane for durability, stretch, and fit; choose heavier, fully cushioned socks for long resort days and thinner, performance‑fit socks for tight boots or backcountry tech setups. Pay attention to targeted cushioning, over‑the‑calf lengths for alpine boots, and technologies that lock the sock to the foot for consistent fit and reduced blister risk.
• How do Smartwool base and mid‑layer fits run and how should I size for mobility and insulation?

  Smartwool uses articulated fits and stretch blends (commonly around 97% Merino/3% elastane) so base layers are typically worn snug to maximize moisture transport and layering; mid‑layers can be slightly roomier to trap air for insulation. If you’re between sizes, size down for a trimmer NTS base and size up for a mid‑layer meant to fit over other garments.
