Under Armour crew Baselayer

[This review was collected as part of a promotion.] It fits well and feels very comfortable on. I wasn't expecting it to be so great but my grandson lives it

Excellent quality product.

[This review was collected as part of a promotion.] The snug fit is nice but length for torso is unusually short.

Slightly snug

[This review was collected as part of a promotion.] Bought for my 12 year old to wear for cross country. It was a bit more snug than he would’ve preferred so he never ended up wearing it.

[This review was collected as part of a promotion.] Was good quality but I felt it ran small. I would order up a size.

Keeps my kids warm

[This review was collected as part of a promotion.] What can I say, my kids play sports and it’s cold outside. These base layers fit them great and keep them warm. I found them on sale too for an extra bonus.

Warm base layer for kids

[This review was collected as part of a promotion.] Great base layer for my son during fall/winter sports. The inside is brushed which was super soft when it arrived but after 1 wash/dry has lost its soft feeling. That’s disappointing but still keeps him warm and good value.
