Training layer
Light coverage that keeps pace with the session
The Performance Airknit Fitted Quarter Zip is shaped for warm-ups, strength work, runs and the walk home afterward. Its smooth lightweight knit follows the body without the bulk of a sweatshirt, while the short zipper lets you open the neckline as your effort and temperature change. The clean pocket-free front stays streamlined under a vest or jacket and looks polished enough for the rest of the day.
Performance features
Purposeful details from collar to hem
Lightweight Airknit
A fine, smooth performance knit keeps the layer light on the body and allows natural airflow during warm-ups and moderate training.
Fitted athletic shape
A close line through the chest, waist and sleeves reduces loose excess fabric while preserving comfortable movement.
Adjustable quarter zip
Open the short front zipper when you need more airflow, or close it into the stand collar for added neck coverage.
Long-sleeve coverage
Slim long sleeves add light coverage for cool gyms, early runs and changing outdoor temperatures.
Low-bulk construction
The plain pocket-free front and simple cuffs layer cleanly beneath a jacket without heavy ribbing or bulky trim.
Versatile solid colors
Ten colors move easily between training shorts, joggers and casual trousers for a simple athletic rotation.
Airknit fabric
Smooth, light and made for movement
The fine-gauge knit has a soft matte surface and an easy drape rather than the thick hand of fleece or a traditional sweatshirt. Gentle folds form naturally at the shoulders, elbows and waist as you move. The fabric sits close to the body, making this a useful first layer in cool conditions or a light outer layer when the day is mild.
Construction
A clean athletic profile
Short center-front zipper for adjustable ventilation
Small stand collar that sits neatly open or closed
Plain front with no chest pocket or visible graphic
Close athletic torso with a straight lower hem
Long fitted sleeves with simple self-fabric cuffs
Lightweight knit with soft movement folds
Close without feeling heavy
The fitted body follows the chest and waist for a streamlined look, while the fine knit remains visually light and flexible through the sleeves.
Control airflow at the neckline
Wear the zipper open during higher effort or close it higher for a clean stand-collar profile before and after training.
Outdoor movement
Ready for warm-ups, miles and recovery
Long sleeves provide comfortable light coverage for early runs and cool-down walks, while the fitted shape stays tidy in motion. Pair it with running shorts for cardio, training pants for the gym, or casual joggers when the session is finished. The solid colors keep the look focused and easy to coordinate.
Color range
Ten colors for training and everyday rotation

Check the chest
Measure around the fullest part of the chest with the tape level and relaxed, then compare the feel with a fitted training top you already wear.
Check the sleeve
Compare shoulder-to-wrist length with a long-sleeve performance top that reaches the wrist without pulling.
Check the body length
Measure from the highest shoulder point to the hem and compare it with your preferred training-layer length.
Care for the lightweight knit
Always follow the sewn-in care label. Close the zipper before washing, turn the top inside out and wash with similar colors. Avoid fabric softener and unnecessarily high heat to help preserve the smooth surface, fitted shape and zipper area.
Remove promptly after washing and reshape while damp. Air drying or low heat helps reduce stress on the fine knit and keeps the collar and hem sitting neatly.
