The Rapha Merino long-sleeved undershirt will keep you cool in the scorching temperatures of July and warm on the frigid January descents. A good base layer helps regulate body temperature in all weather conditions, transferring moisture away from the skin and proving to be a vital performance aid. Rapha base layers are made of merino wool and are naturally antibacterial and odor-resistant. They absorb water vapor extremely quickly, are soft on the skin and do not itch. Rapha's merino wool base layers are available in three styles; sleeveless, short sleeve and long sleeve. All seams are flatlock to prevent rubbing and are positioned behind the shoulders to prevent rubbing of the bag or suspenders while cycling. Base layers are fitted and cut long in the back for a better fit on the bike.

• Flatlock seams.
