Men's Thermal Shirt - Long Sleeve Fleece Lined Crew Neck Undershirt for Under Flannels

You put on a good flannel or a pressed shirt, and it's still cold, because a thin cotton thermal shirt doesn't do much once you're outside. A thicker layer usually means a collar that pokes out at the neck and sleeves that bunch at your elbows. This long sleeve undershirt for men is cut to stay out of sight, and it's lined with soft fleece on the inside.

The trick is in the two faces of the fabric. The brushed plush fleece sits on the inside, against your skin. The smooth polyester knit sits on the outside, so your shirt glides over the top instead of catching on it. You get real softness underneath, and your shirt still hangs the way it should.

The neck is where most undershirts give themselves away. This one is a narrow, low crew with a slim band and two rows of stitching, so it stays below your collar. Open the top button and you won't see a stretched-out white ring at your throat. With no pockets, zips or print on it, there's nothing to show through a lighter shirt, and in Dark Gray or Black it stays out of sight under darker ones. Sizes run all the way up to 5XL, so bigger frames get a proper fit under a shirt too. The close knit cuffs keep the sleeves at your wrists, under your shirt cuffs.

A few straight answers. It's an undershirt, not an outer layer, so it won't stop wind or rain. The maker gives no temperature rating and we won't invent one. We also don't have garment measurements from the maker yet, so we won't guess at the fit.

Key Features:

• A soft brushed fleece lining sits against your skin under any shirt.
• A smooth outer knit lets a dress shirt or flannel slide on without catching.
