Cycling in the rain and what you wear underneath

Short answer: Rain gear keeps water out and sweat in. That is why the base layer matters as much as the jacket once the ride lasts more than twenty minutes.

The moisture comes from inside

Under a sealed rain jacket you get wet from your own sweat. A layer that moves moisture makes the ride bearable. See bamboo undershirts for men.

Socks get wet anyway

Water runs down your leg and into the shoe. A spare pair of socks at work is the only real solution. See bamboo socks for men.

Change on arrival

Undershirt and socks are the two layers carrying most moisture. Change them, and the rest can dry on a hanger. See bamboo underwear for men.
