Zip-Ups

$90as of Sep 15, 2026. Check the current price at Under Armour

The verdict

A capable grid-fleece full-zip for men who want a warm, breathable training midlayer, fairly priced.

Fit

Expect a modern athletic cut that trims closer to the body; if you prefer room to layer, size up.

Quality

Typical of the brand's Unstoppable line, a grid-fleece interior for warmth-to-weight and generally clean seams and a reliable full zip.

Price check

Around 90 dollars is upper mid-tier for a technical fleece; the grid construction and brand engineering make the price defensible if not a bargain.

Best for

Men who want a breathable, warm midlayer for training or active cold-weather use.

Care

Machine wash cold and tumble dry low; avoid softeners, which can clog the grid fleece and reduce breathability.

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.
