Zip-Ups

$42as of Sep 15, 2026. Check the current price at Under Armour

The verdict

A fair buy under $45 for anyone wanting a light knit warm-up layer for practice or travel, not warmth.

Fit

Warm-up styles from Under Armour typically run an athletic-regular cut with room through the shoulders; most buyers can take their usual size. Sleeves may run slightly long, as is common with track-style tops.

Quality

Expect a mid-weight knit with standard zipper and stitching quality typical of the brand's team line — serviceable through seasons of regular wear, not a heavy-duty piece.

Price check

At about $42 this sits in the budget-to-mid band for zip-ups, and the price reads as fair for a team warm-up layer rather than brand tax.

Best for

Athletes and coaches who want a simple knit layer for warm-ups, sidelines, and travel days.

Care

Machine wash cold, tumble dry low, and skip fabric softener to preserve any wicking finish.

True to size

Under Armour's everyday lines fit true to size with a deliberately roomy, athletic-loose cut rather than a tailored one.

Owner reviews of the core Rival Fleece hoodies and joggers repeatedly land on "true to size," with the cut described as loose and comfortable rather than baggy — several hoodie owners say to size down only if they want a trimmer fit. Sizing guides likewise report the brand fits true to your usual size once you pick the right cut, since Under Armour labels pieces by cut (loose vs. fitted vs. compression) and the fitted and compression styles are intentionally much snugger than the casual gear. Reviewers note the tees and tops run long and boxy rather than fitted, and a minority of jogger buyers found the slimmer athletic cuts snug enough to size up.

Sizing advice: Order your usual size in the casual fleece, tees, and joggers — size down only if you want a closer fit in the roomy cuts, and expect the fitted/compression-labeled styles to run much snugger by design.
