The Flat Head Heavyweight Thermal in Black features a slightly heavier honeycomb mesh thermal fabric than previous iterations. This 12.5oz thermal fabric is both comfortable and warming, and comes in a standard long-sleeve format for an easy-going base layer or primary layer. These have a beautiful micro-waffle structure with high elasticity to make this comfortable in the width (chest/torso), but still appropriate in the length without shrinking or stretching too much. These are constructed with a 1960s Union Special flat seam machine for the side-seams, making this an excellent thermal that will lay flat against your body with no bumps.
These have a softer feel than most thermals and due to the close knit micro-waffle structure, it feels more like a soft-thin sweater than a thermal.
Note: These generally run small, recommend sizing up at least one or two sizes depending on how you want it to fit. The body measurements may look small (especially in the chest), but the width will easily stretch accordingly. We would recommend going by the shoulder measurement for selecting your size, as well as taking into account the length of the overall thermal.
Model: 6'0" and 175 lbs (currently closer to 170 lbs) wearing size 40 | L for a slim fit. The size 40 | L runs a bit short on the model as well. Model can also wear size 42 | XL for a slightly more relaxed fit and additional length. Model prefers the size 42 | XL overall given the length, but could see himself wearing size 40 | L if he only planned to wear the thermal as a base layer underneath something else.
