How to Measure Your Own
1. Chest
Measure around the fullest part of your chest, keeping the tape comfortably under your arms and across your shoulder blades.
2. Arm
To measure sleeve length, start from the top of your shoulder (near the neck) and measure down to the wrist bone.
3. Waist
Measure around the narrowest part of your waist, keeping the tape comfortably snug but not tight.
4. Body Length
Measure from the shoulder seam (near the neck) down the back to the bottom, typically around the hips or waist.
5. Shoulder Width
Measure across the back from one shoulder seam to the other, just across the top of your shoulder blades. This will give you the shoulder width for a better fit.

Why You'll Love It
Natural Warmth & Comfort
The Flux Merino Wool Men’s Top Base Layer offers natural warmth and breathability thanks to its 100% Merino wool construction. The 15.5-micron fibers provide a soft, itch-free feel, keeping you comfortable during long outdoor adventures or casual days.
Thanks to its moisture-wicking and odor-resistant properties, this base layer will keep you dry and fresh all day. The Merino wool allows for effective temperature regulation, making it perfect for both high-energy outdoor activities and relaxed winter outings.
What's the Difference Between Merino & Synthetic Layer？
Merino Wool Base Layer regulates microclimate through its natural fiber structure, gradually absorbing sweat and converting it into sustained warmth while lanolin components break down odor molecules, forming a biological thermal layer in multi-day cold exposure.
Synthetic Base Layer relies on chemical wicking tech for rapid moisture expulsion, with microfiber networks enabling instant heat evaporation during high-intensity activities—though evaporative cooling risks sudden temperature drops. The former trades biologically-driven resilience for enduring comfort; the latter leverages industrial precision for tactical bursts.

How to Choose Your Perfect Ones?
We highly recommend that you choose the right snow clothing for your needs and don't just stick to the parameters!
Core Principle: Moisture is the Enemy
A base layer’s mission: wick sweat relentlessly while maintaining thermal efficiency.
Key Metrics: Breathability (for high-intensity) | Insulation (for static/cold)
Critical Fail = Cotton (traps moisture, freezes you like ice pop).

- Alpine Skiing (Downhill/Racing): Synthetic Polyester.
- Backcountry Ski Touring/Expeditions: Merino Wool (200+ GSM).
- Freeride/Off-Piste Skiing: Merino-Synthetic Blend.
- Ski Mountaineering/Ice Climbing: Reinforced Synthetic Fibers.
- Freestyle/Park Skiing: Lightweight Mesh Synthetics.
Quick Logic:
- "Bombing icy slopes? Drenched in sweat?" → Synthetics
- "Multi-day trek in -30°C?" → Heavyweight Merino
- "Park laps + icy chairlifts?" → Merino blend

Hidden Pain Points
- Synthetic Snags: Odor buildup after friction (trapped bacteria).
- Merino Myths: "Delicate" rep—reality: modern knitting resists pilling.
Field Fixes: - Cold/Wet Conditions: Double-layer lightweight Merino.
- High Friction Zones: Seamless synthetic sleeves under pack straps.

Three-Layer System
The concept of the three-layer system originated from outdoor activities, designed to help people stay warm and dry in extreme weather conditions. Through a scientific layering approach, the base layer wicks moisture, the mid layer provides insulation, and the outer layer offers wind and water resistance while maintaining breathability. Although initially developed for mountaineering and exploration, this method is now widely used in sports like skiing, ensuring comfort and performance in various environments.
