Rated 5 out of 5 by from Big Improvement This year's model is a big improvement over last year's. The sleeves have been lengthened back to a normal length so you can wear the shirt by itself without looking strange (previous year had these awkward shortened sleeves which made it look like the garment was incorrectly made). Same toasty warmth and buttery feel to the fabric. A staple in my wardrobe that I wear daily in the winter, whether lounging indoors, going outside, and even as a skiing base layer. Very versatile product. Please continue making, particularly the green and grey colors which look beautiful but have sold out too quickly :( For size reference I am 6'2 and 170 pounds and the Large fits perfectly.

Rated 2 out of 5 by from This is no longer the HEATTECH I know First the color is completely different from before, they are no longer white, instead you will be getting something creamy. Second the sleeves are much longer than the old one and the loose fit really make me feel uncomfortable. Uniqlo we need the old Heattech back!!

Rated 5 out of 5 by from Super comfortable I went with my size for this shirt and it fits like 15% too big. Its kinda long, has a little extra length in the arms/sleeves. Its soft enough, I had to wear it uncomfortable (2 days back to back). Definitely a base layer personally but very soft and warm.
