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.
6. Waist
Measure around the narrowest part of your waist, typically just above your belly button. Keep the tape snug but not tight for an accurate measurement.
7. Hip
Measure around the fullest part of your hips, keeping the tape parallel to the ground. Ensure the tape is snug but comfortable.
8. Thigh
Measure around the widest part of your thigh while standing with your feet slightly apart. Keep the tape comfortably snug for an accurate fit.
9. Inseam
Measure from the crotch seam to the desired length of your pants along the inner leg. Use a pair of pants that fit well for reference.
10. Outseam
Measure from the top of your waistband to the bottom of your pant leg, along the outer side of your leg. This will give you the overall length of your pants.

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!
Waterproof Ratings: Know Your Weather
Water resistance is measured in millimetres (e.g., 8,000mm, 20,000mm) – higher numbers don’t always mean better performance.
- Beginner/resort skiing (gentle slopes, dry snow): 8,000-1,000mm is sufficient for light snowfalls.
- Multi-day trips/wet snow regions: Aim for 10,000-15,000mm with fully sealed seams.
- Backcountry/storm conditions: 20,000mm+ for heavy snow or rain.
Pro tip: Most resort skiers don’t need max waterproof ratings – proper seam sealing matters more than chasing numbers.

Breathability: Match Your Effort Level
Balancing waterproofing and airflow prevents sweat buildup:
- Casual skiing: Moderate breathability (5,000-8,000g/m²) works for relaxed runs.
- Intensive skiing (off-piste, moguls): Prioritize high breathability (10,000g/m²+) to avoid overheating.
Key fact: Breathable fabric alone won’t keep you dry—pair it with moisture-wicking base layers.

Warmth Strategy: Layer Smartly
Ski jackets themselves don’t provide warmth—insulation comes from mid-layers!
- Thin shell jackets (non-insulated): Ideal for most skiing—add/remove mid-layers as needed.
- Insulated jackets: Suitable for cold (-15°C or below) or low-activity skiing, temperature tolerance depends on the type and thickness of the insulation.

Hidden Essentials
- Mobility-friendly design: Sleeves should cover wrists when stretched forward.
- Weight matters: Under 800g jackets reduce fatigue for active skiers.
- Ventilation zips: Underarm/chest vents help regulate temperature during variable weather.
- Reinforced zones: Look for abrasion-resistant panels on knees, elbows, and seat areas.
- Snow seal: Detachable inner snow skirts keep powder out without restricting movement.

2L or 3L? What's the Difference?
Discover the difference between 2-layer and 3-layer designs with ChillCarve. Choose the perfect balance of durability and comfort for your needs.
2L and 3L refer to the number of structural layers in the outermost part of a snow jacket. The main difference lies in whether there is a third inner layer tightly bonded to the second breathable membrane. This affects breathability, durability, weight, and comfort.
Compare the Fabric
| Comparison Criteria | 2L Fabric | 3L Fabric |
|---|---|---|
| Definition of Layers | 2L and 3L refer to the layers of the outermost fabric, not the entire garment. They define fabric construction, affecting waterproofness, breathability, durability, and comfort. | |

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.
