The most common layering mistake isn’t the wrong fabric. It’s the fourth layer — the one you packed out of fear and then wore out of guilt, sweating uphill at 8 a.m.
Our system is three pieces, and the discipline is in the gaps between them. The Strata Merino Base handles skin: 18.5-micron wool that moves moisture and doesn’t smell on day three. The Col Fleece or Vantage Down Hood handles warmth — fleece when you’re moving, down when you’ve stopped. The Ridgeline Shell handles weather, and only weather.
The rule we teach on test trips: start cold. If you’re comfortable in the parking lot, you’re overdressed for the climb. Layer changes happen at transitions — treeline, summit, first tee — not whenever you feel like it, because every stop costs heat and daylight.
Ski morning, golf afternoon? Same base, same rule. Swap the shell for the wind layer, leave the down in the car, and let the merino do what it’s been doing since 6 a.m.
