Frequently asked questions

How does the relaxed fit of this thermal shirt compare to a standard fitted tee?
This garment is designed with a relaxed, comfortable cut through the body rather than a slim or tailored silhouette. Shoppers should expect more room around the torso and arms compared to fitted base layers.
What fabric construction provides warmth in this thermal layer?
The shirt is made from mid-weight cotton knit featuring a waffle texture designed to provide added warmth without excessive bulk. This specific material choice helps maintain comfort while offering insulation for everyday wear.
Does every shirt in the 3-pack have buttons at the neckline?
No, only one item in the pack features a henley placket with buttons at the front. The other two shirts in this mix-and-match set have a standard rounded neckline.
Is this thermal shirt suitable for use as an underlayer for school uniforms?
Yes, it is marketed as a go-to layer for everyday wear and can be worn under other garments. The mid-weight cotton construction and ribbed cuffs help keep the sleeves in place while providing warmth.
