The verdict

A fair pick for someone wanting a technical take on a flannel; check the cut, as the listing mixes men's and women's labels.

Fit

Outdoor flannels from this brand usually fit relaxed for layering; take the usual size, but confirm whether the stocked cut is men's or women's given the conflicting tags.

Quality

Expect a brushed woven, likely with synthetic content for faster drying than traditional flannel; construction should be sturdy for regular outdoor wear.

Price check

At about $65 it is mid-tier for a performance flannel; fair, though plain cotton flannels cost less and the premium here buys technical fabric, not luxury.

Best for

Cool-weather hikers and campers who want a flannel that dries faster than cotton.

Care

Machine wash cold and tumble low to keep the brushed face from matting.

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 button-ups: what reviews say

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.

Strengths: Owners repeatedly single out the lightweight, breathable, wrinkle-resistant fabric that stays comfortable through hot weather and frequent washing.
Watch out for: Owners of the technical fishing-style button-downs say the cut runs small and recommend ordering a size up.
Sizing: The casual coaching-style button-ups fit true to size; the technical fishing-style shirts run small, so size up.
