I also like that cotton tends to feel less irritating than some synthetic fabrics.
How I Check the Fit
Fit matters a lot to me when buying long johns. I make sure they are snug enough to stay in place but not so tight that they feel restrictive. I usually check the waistband, leg length, and whether the fabric stretches comfortably. If I plan to wear them under jeans or work pants, I prefer a close fit without extra bulk.

Not all cotton is the same, so I pay attention to the fabric weight and stitching. I like long johns that feel durable but still soft. In my experience, thicker cotton can provide more warmth, while lighter cotton works better for layering. I also inspect the seams because strong stitching usually means the pair will last longer.

I’m willing to pay a little more for better stitching, softer cotton, and a fit that works well for me. For me, value matters more than cost alone.
