UA Tech Infant Boys' Short Sleeve & Joggers Set

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?

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.
