Three layers keep you warm on an 18,000ft pass like Umling La without the bulk that kills mobility.
Key Riding Guidance & Highlights
The riders who stay comfortable at 18,000ft aren't wearing the thickest jacket — they're wearing the smartest three layers. The 3-layer system lets you manage a 25°C daily temperature swing without ever stopping to change your whole outfit.
The three layers
- Base (wicking): Merino wool against the skin pulls sweat away and stays warm even when damp. Avoid cotton.
- Mid (insulation): A fleece or light down jacket traps warm air. This is the layer you add and remove most often.
- Shell (protection): A windproof, waterproof outer blocks the wind chill that does the real damage on a pass. A bright colour helps the group keep you in sight.
How to use it
Start a cold morning with all three. Dropping into a warm valley, shed the mid-layer at a stop. Climbing back up, add it before you get cold, not after.
Our tip: During Himalayan Motorcycle Tours, wind—not air temperature—is what really freezes riders on high passes. A good windproof shell can make all the difference, often mattering more than a bulky jacket.
