What to Wear Cycling in 40°F (4°C)
Cycling at 40°F (4°C) feels significantly colder due to wind chill. At 15 mph cycling speed, the apparent temperature drops to around 28–30°F (-2°C). This is serious cold-weather riding — a full thermal layering system is required and exposed extremities will become painful within minutes.
Upper body
Lower body
Extreme winter bib tights
articulated windproof panels front and back
Extremities
Lobster-claw mittens or bar pogies
fingers share heat in grouped chambers
Cycling-specific winter boots
insulated footwear for sustained sub-zero rides
Full balaclava
exposed facial skin loses heat and risks frostbite
Ski or clear goggles
eyes need protection in wind and precipitation at low temps
Notes
- ·Prioritise warm extremities over a heavier jacket — hands and feet lose heat fastest.
Tips
- →Assume you will feel colder than 40°F — any wind at all will push the apparent temperature into the low 30s°F.
- →Neoprene toe covers or shoe covers are essential — wet, cold feet are the most common complaint.
- →Merino wool base layers outperform synthetic for all-day cold-weather comfort.
- →Shorten your warm-up phase — standing still at 40°F before the ride starts will cool you rapidly.

FAQ
What to wear cycling in 40 degrees Fahrenheit?
Softshell jacket over a long-sleeve thermal base layer, thermal bib tights, insulated full-finger gloves, neoprene toe covers, and a thermal headband. Wind chill at cycling speed makes 40°F feel like the low 30s°F.
Is 40°F too cold to ride a bike?
No — 40°F is manageable with the right kit. Many cyclists prefer this temperature for long endurance efforts. The key is wind protection and covered extremities.
