The verdict
Fit
Newborn sets run to standard infant sizing; buy by the baby's age or weight range and expect an easy, roomy fit.
Quality
As UA's entry tech infant range, expect lightweight, soft synthetic fabric with simple, comfortable construction and snaps or an easy waistband for changes.
Price check
At about $28 for a two-piece newborn set the price is fair for the budget infant tier.
Best for
Parents or gift-givers wanting a branded, easy-wear outfit for a newborn boy.
Care
Machine wash cold on gentle and tumble dry low; wash before first wear for a newborn.
Fit check: Under Armour
True to sizeUnder 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 owners report about Under Armour pants
Owners across Under Armour's woven and fleece pants report solid build quality that survives repeated washing without holes or seam failures for most wearers, though a subset describe the polyester ripstop shell as feeling plastic-like rather than natural against the skin. Fit runs inconsistent: several buyers found the woven styles tight through the waist and thigh and short in the leg, prompting a size-up recommendation, even as other reviewers call the same pants true to size.
- Strengths
- Reviewers consistently praise the durable, easy-care fabric that holds up across many washes without tearing.
- Watch out for
- The polyester ripstop shell reads as plasticky rather than soft to some wearers, and a portion of buyers report the fit running tight or short in the leg.
- Sizing
- Sizing is inconsistent between reviewers on the woven styles — several recommend sizing up for a fuller fit through the waist and thigh, since inseams can run short.
