Homespun Knitwear's Long Sleeve Thermal Crew in Bronze is a beautiful earthy-toned bulky heavy waffle knit from Japan. These are 100% cotton and weigh around 450gsm, making these one of the heavier thermals we carry. These are cut slim and will stretch accordingly in the chest and waist. These are finished with flat band rib cuffs for a secure fit at the wrist.
Note: While measurements may look small for your TTS, these generally do run TTS for a slim fit, as the fabric will stretch to fit in the chest/waist. As these are pre-rinsed, you should expect minimal shrinkage. Upon wash, any stretch in the width should come back in (and subsequently stretch back out upon wear). Because the chest measurements are small, you may want to place more emphasis on the shoulder, sleeve, and length measurements to determine sizing.
Model: 6'0" and 175 lbs. (currently closer to 165 lbs) wearing size M for a slim fit that hugs through the chest/waist, but can be a tad short in length depending on how he wears it (base layer or only layer).
