The verdict

A lined women's running short at a fair price; a reliable everyday pick for runners wanting built-in coverage.

Care

Machine wash cold and tumble dry low to protect the shell fabric and liner.

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.

Under Armour shorts: what reviews say

Owners report Under Armour's shorts line holds its shape wash after wash: stitching stays intact and the printed logo doesn't crack or peel, and heavier compression and HeatGear styles are called 'incredibly durable' with fit that holds up longer than competing brands. The exception is UA's lightest woven training shorts (e.g. Vanish Woven), where reviewers flag the thin polyester face fabric as prone to abrasion and fraying under repeated barbell or turf contact, describing it as 'not the best for long-term durability' in heavy use.

Strengths: Reviewers consistently praise how well the shorts hold their fit, stitching, and printed logo after repeated washing.
Watch out for: The lightest woven training styles are reported to abrade and fray under heavy rig or barbell contact.
Sizing: Owners describe the fit as true to size, with big-and-tall (XLT) sizing praised for offering enough length for taller wearers.
