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.

What's my size at Under Armour?

Under Armour's button-down shirts — both the coaching-style casual shirts and technical fishing shirts like the Fish Pro Hybrid — use lightweight stretch-woven fabric rather than traditional dress cotton. Owners consistently call them light, breathable, and cool even in hot weather, describing wrinkle-resistant, no-iron durability through frequent wear and washing. The casual coaching styles fit true to size; owners of the technical fishing-style shirts more often say the cut runs small and recommend sizing up.
