OVERVIEW: Long days, unpredictable weather and limited stowaway space are huge considerations, especially when it comes to deciding what to bring on a cycling adventure. The Flagstaff RT Vest was designed to deal with this very conundrum. Lightweight and easily packable, the Flagstaff utilizes ClimaStretch fabric throughout the front, sides and shoulder areas to provide a layer of wind and water protection. Plus, with 360-degrees of reflectivity, the silicone backed RT waistband is added safety in low-light conditions against passing motorists, making this an ideal piece for big mountain climbs, changing weather and variable light conditions.

WHY FLAGSTAFF? We’ve named this highly versatile gilet for the infamous Flagstaff Mountain climb in Boulder, Colorado. It’s truly one of our favorites and is accessible even in the early spring or late fall since the east facing switchbacks are often the first in Boulder to melt after a storm. Noted for its intense 11% average gradient climb, even the fittest cyclists are hit with rising heart rates and body temperatures, and once at the summit, a chilly and exhilarating descent. The Flagstaff RT Vest was developed for just that sort of ride.

PAIR WITH: In the low-light, shorter days of spring and fall, you’ll want to pair the Flagstaff RT Vest with the Summit RT Jersey and Summit Raptor 2.0 RT Bibs for the enhanced safety of their reflective arm and leg grippers. Plus, the next-to-skin fit of the Summit RT Jersey pairs perfectly with the Flagstaff RT Vest. Later, as the miles roll by and temperatures rise, you’ll be happy you have the heat-deflecting, moisture-transfer, Flash body fabric and Cytech Endurance Anatomic chamois of the Summit Raptor 2.0 bibs.

 FABRIC & CONSTRUCTION: The ClimaStretch fabric through the front body, shoulders and sides of the Flagstaff RT provides exceptional wind-stopping and water-blocking protection, while Silhouette Engineering around the shoulder openings creates an unrestrictive next-to-body fit that reduces high speed flapping. Two pocket access points on either side of the rear panel have been designed to create an ergonomic pass-through to your 3 jersey pockets. Magnetic closures collapse as soon as your hand exits, quickly sealing the access point and eliminating any unnecessary fiddling with snaps or zippers . Built for all-day use, the BreatheLITE mesh throughout the back and under the arms regulates temperature while climbing, descending and spinning along long flat roads. The RT waistband will ensure 360 degree reflective visibility in low-light conditions.

Measuring Tips 


Using a soft measuring tape, bring the tape across your back under each arm, around the front. For women, measure the widest point of the bust. For men, measure around the largest part of your chest.


Bend to one side to find natural indentation in torso. This is your natural waist. Run tape around waistline, keeping tape parallel with floor. 


Stand on a level surface with feet together. Measure around fullest part of hips and bottom (approximately 7" - 9" below waistline), keeping tape parallel with floor.
