Women's Ascent Climber's SS Jersey - Flux

Size & Fit Chart

Race slim fit cycling jersey*All sales are final on outlet items after 14 days of purchase.

OVERVIEW: The Ascent Climber's has been designed for those who want a lightweight, extremely breathable, aerodynamic-fitting jersey but prefer a more traditional stand-up collar and 3 full-size rear pockets. Front panels and Euro-length sleeves are constructed using a super stretchy, wicking fabric. The back of the jersey is made up of a fine mesh allowing for the ultimate in heat dissipation. At just 119 grams in a size medium, the Ascent Climber's is extremely lightweight, but we've engineered it so the structural integrity keeps the loaded pockets from sagging. It's a great choice for hot weather, long climbing days or under a jacket. Because of the meshy back fabric, we always recommend wearing sunscreen on your back and shoulders when wearing this jersey.   

Peloton Magazine"Living in the rarefied air of Colorado, at the foot of the Rockies, you'll learn a thing or two about climbing. Pactimo has invested its climbing knowledge into the Ascent Climber's jersey. An all-new fabric, Feather-Stretch, combined with Zero-Weight mesh, deliver a jersey that weighs just 120 grams and is the most breathable jersey Pactimo has ever made. Despite the ultralight weight, Pactimo has graced the jersey with robust pockets that can handle a day's worth of gear without yanking your collar down or shifting from side to side." 

 FABRIC & CONSTRUCTION: The key to the unparalleled breathability and comfort of the Ascent Climber's Jersey is the combination of FeatherStretch body fabric in the sleeves and front panels and Zero-weight mesh in the back. Each provides the necessary stretch for a next-to-skin fit, without sacrificing the structure needed for loading your pockets on a long ride. A soft silicone waist gripper covers the rear half of the jersey for stability during movement but has been removed from the front half of the jersey to reduce weight and increase comfort. Longer sleeves shape your arms and lie just below the bicep, providing aerodynamic coverage and increased comfort. Includes a two-piece standing collar, 3 full-size pockets, anti-chafe neck tape and full-length YKK zipper.

There is no better companion to the Ascent Climber's Jersey than the Summit Stratos "12-Hour" Bib Shorts. The Stratos Bibs provide uninhibited movement, long distance comfort and body temperature regulation during exertion through the heat dissipating Cerami-K body fabric. Enhanced performance comfort comes from the MAB X Power straps and Cytech Endurance Anatomic Super Air chamois. When you turn back at the summit, you’ll want the easily-packable and form-fitting Divide Packable Wind Vest to keep your core temps regulated on the chilly descent. A Pactimo Cycling Cap rounds out the set, keeping your head cool and sweat out of your face. (Quick Tip: Douse your cap with cold water on a long hot day to drop your body temperature after a hot, exposed climb.)

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.
