Staying warm outside isn't about one thick jacket — it's about layers you can add and remove as conditions and effort change.
Base layer: manage moisture
Sits against your skin and moves sweat away. Merino wool and synthetics work well; avoid cotton, which stays wet and chills you. Base layers
Mid layer: insulate
Traps warmth. Fleece is breathable and durable; down and synthetic puffies are warmer for their weight. Synthetic insulation handles damp better than down. Fleece and puffy jackets
Outer layer: block wind and water
A waterproof-breathable shell protects your other layers. Look for adjustable hood, cuffs, and pit zips for venting. Rain shells
Don't forget the extremities
- Warm hat or headband
- Gloves, plus a backup pair if it's wet
- Wool socks and appropriate footwear
How to use the system
- Start cool. You'll warm up quickly once moving.
- Shed before you sweat. Wet layers lose warmth.
- Add a layer at breaks before you get cold.
