How warm should my base layer be?
Light
Breathable and sweat wicking, for when you need a touch of extra warmth during shoulder season. Best for running, cycling and any high-output activity where you'll be working up a sweat.
Warm
Lightweight warmth with moisture wicking, so you can turn up the pace without overheating. Best for cross-country skiing, winter running or whenever you'll need more warmth on the go.
Warmer
Midweight insulation with moisture management that helps prevent the chills. Best for cross-country skiing, backcountry skiing, snowshoeing and camping in cooler temps.
Warmest
Grid construction traps in more air so you stay warm even during intense cold-weather activities. Best for winter camping, trekking, ice climbing or whenever you're out in the deep cold.
Merino or Synthetic: which material is right for you?
Merino
Naturally warm, and softer next to skin than traditional wool. Plus, Merino is naturally antimicrobial, making it ideal for multi-day adventures where comfort is key.
Synthetic
Quick drying, durable and built to perform when you push the pace. Synthetics are typically more budget-friendly than Merino, letting you get more warmth for less investment.

#MECSTAFFER PICKS
“Don't underestimate a solid base layer during a stop and go day on the slopes. A Merino or synthetic mid-tier layer keeps you warm on the chairlift and wicks moisture when you're carving hard.”
