The Louis Garneau Modesto Switch Jacket keeps us prepared for all the day's riding conditions. The lightweight fabric is wind- and water-resistant to keep chilly air and surprise storms off our jersey while we power ahead. When things warm up, this jacket's convertible construction comes in handy--we ditch the sleeves and shoulders to combat warmer weather. Vents on the back of the vest allow airflow, but if that's still too much, the fabric is so light that it easily packs into our jersey's pocket.
