OVERVIEW: Reflective Cycling Clothing Designed for the inclement weather of the swing seasons, the Flagstaff RT Jacket is the ideal jacket for those long days in the saddle when you know the weather could turn on you. A streamlined fit and performance-driven minimalism provide windproof and water-resistant protection without sacrificing breathability. The easily stow-able, lightweight jacket includes two rear entry, magnetically closing passthrough openings for easy jersey pocket access. Spring and Fall riding typically bring more low-light conditions, so we have included 360 degree visibility with our Reflective Technology (RT) waistband.

Peloton Pactimo Review"Over the last few seasons we have been consistently impressed with the clothing coming out of Colorado based Pactimo and the Flagstaff RT Jacket is another piece seeing heavy rotation here at Peloton. The collar is tall. The fit is dialed for layering in an aggressive position and it stows easily in a jersey pocket."

Bicycling Review

Josh, Brand ManagerEMPLOYEE RECOMMENDATION: "The Flagstaff RT Jacket is the perfect companion for high altitude riding during the summer and the shoulder seasons. The wind and water resistant front fabric keeps you warm and dry. I love how the mesh back breaths when I am climbing and my body starts to heat up. One of the best parts of the Flagstaff is the RT band that runs all the way around the jacket. It makes you that much more confident of being seen as the sun sets!" - Josh, Brand Manager

CAUTION! Sunscreen can damage RT fabric. Learn more »

WHY FLAGSTAFF? Boulder’s infamous Flagstaff Mountain climb is one of our favorites. The east facing steeps and switchbacks are often one of the first in Boulder to melt after a storm, making it an ideal climb throughout the cool mornings and stormy afternoons of the spring and fall. With an average gradient of 11%, your heartrate and body temperature increase rapidly on the ascent and cool quickly on the way down. We designed the Flagstaff for this exact situation with wind/water protection across the front and leading edges and a mesh jersey weight fabric in the back and underarm for breathability and temperature regulation.

PAIR WITH: On those cooler spring morning, a set of knee warmers and Alpine RT Thermal bib shorts are the ideal companion. Wear the Flagstaff RT over an Alpine RT Thermal or Summit Aero RT Jersey depending on the beginning and ending temperatures of your ride. A Neck Gaiter and cycling cap will cut the chill of the descent, keeping you adequately warm without overheating.

FABRICS & CONSTRUCTION: The ClimaStretch fabric through the front body, sleeves and sides of the Flagstaff RT provide the necessary wind-stopping and waterproof protection. Not simply protecting you from the elements, the stretchable fabric creates an unrestrictive next-to-body fit reducing that infamous flapping sound in high-speed descending. Built for all-day use, the BreatheLITE mesh throughout the back and under the arms regulates changes in temperature as you climb, descent and spin across long flat roads. The RT waistband will ensure 360 degree reflective visibility in low light conditions. The Gusseted cuffs provide warmth by creating a better seal from the wind with your gloves and wrist on descents.

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.
