Men's Horizon Shirt - Black

Fit depends on which cut you pick: the Classic line is slim, tapered, and reads small on average builds, the Relaxed line is much roomier, and the all-cotton fleece shrinks a size's worth in a hot dryer.

Owners and testers split along the brand's two fit lines rather than one direction. The Classic fleece is cut athletic — broad shoulders tapering to the waist — and one hands-on tester found several pieces "ran small" against the brand's own size charts, with pants also running short in the leg. Meanwhile hoodie reviewers report the opposite out of the box — one called it "larger than its true size" and baggy in the arms — but the 100% cotton shrinks roughly 3-5% in the dryer, and another reviewer's slightly-large medium settled to a proper fit after one wash-and-dry. Reviewers note the Relaxed fit runs about 5 inches bigger in the chest than Classic at the same marked size, so the label alone doesn't tell you the fit.

Sizing advice: Keep your usual size in the Classic fleece and dry on low to let the 3-5% shrinkage dial in the fit; choose the Relaxed cut (not a size up) if you want room, and expect pant inseams to run short.

Editorial coverage of American Giant's button-up shirts centers on the flannel and linen models; reviewers report sturdy buttons, durable construction, and fabric that is light enough to breathe but warm enough to layer. A month-long test of the wider range found no fading, loose threads, or shrinkage and concluded the quality warrants the price. Buyer reviews mostly agree on construction, though some report pilling, fading within the first washes, and hardware failures on other garment types.

Strengths

Reviewers consistently report durable, US-made construction with sturdy buttons and stitching that hold up to regular washing.

Watch out for

The most repeated complaint is that pieces run small against the brand's own size charts, with scattered buyer reports of fading and pilling.

Sizing

Testers found items run small compared to the brand's sizing charts, so consider sizing up if between sizes.
