Reviews Summary

Customers say these thermal shirts are warm, comfortable, and well-made with thick, quality fabric. Many appreciate the perfect fit and find them ideal for layering or wearing alone. The material keeps users warm during cold weather and outdoor activities. However, some mention the fabric can feel stiff initially and sleeves may be tight for pushing up. Common concerns include sizing inconsistencies, with some finding them too small while others note they run large. Several customers report shrinkage after washing, particularly in sleeve length. Despite mixed feedback on sizing, most praise the comfort and warmth these thermals provide.

Great Buy!
I got this on sale, probably because winter is coming to an end, but I love it. I’m generally a pretty warm guy so often when it’s a little cold out a hate to wear a jacket, but I also don’t want to wear a t-shirt, this splits the difference beautifully!

Hi Joseph! We're glad to hear the initial fit was good, but we’re so sorry to hear those shoulders tightened up on you after a wash. A member of our team will be reaching out to you directly via email to help make this right!
