How to dress in precipitation: 1 mm

Practical setup for precipitation 1 mm.

In wet conditions, staying dry inside your system matters more than adding bulk.

Use a weather-appropriate shell outside and quick-drying layers underneath, with ventilation you can adjust on the move.

If you will be outside for a while, bring a dry backup layer and choose footwear that can handle surface water.

In light precipitation, internal moisture build-up is often the real comfort killer.

What to wear:

- Pick a shell that matches expected precipitation intensity.

- Wear fast-drying base fabrics and avoid absorbent inner layers.

- Use pit-zips or front zip venting to control moisture build-up.

What to avoid:

- Treating light precipitation as harmless.

- Building the outfit around cotton next to skin.

- Ignoring hood and cuff sealing in wind-driven rain.

Checklist:

- Read precipitation together with wind and temperature.

- Check hood, collar, and cuff closure before leaving.

- Pack one dry backup item for longer outings.
