Sizing notes

Measurements are stated in inches unless otherwise indicated. CHOOSING THE RIGHT SIZE: If your body measurements are midway between two sizes, select the smaller size for a tighter fit or the larger size for a looser fit. If your body measurements result in different sizes, we recommend using your chest measurement for tops and your hip measurement for pants.

Rated 5 out of 5 by from Outstanding base layer This is the third icebreaker base layer I bought for my husband. He wears the bodyfit basic 200 almost every day during the winter and says it 's best base layer he has ever worn. Expensive, but worth it.

Rated 5 out of 5 by from I wear these everyday, but I have one issue The photos don't always show whether the stiching on the side is a different color as the shirt itself. The blue shirt has white stiching! I wish the stiching was the same color, so it wouldn't stand out.
