The double layer really does trap heat — I noticed the difference on my first cold morning commute compared to my old single-layer crewneck. It's soft against the skin too, no itchy feeling even after a full day of wearing it.
Wore this under a flannel on a 20-degree morning and stayed warm without feeling bulky. The air pockets between the two jersey layers really do trap heat, and the crew neck sits close enough to keep cold air from sneaking in.
The double-layer knit on this crewneck is no joke — those little air pockets actually trap heat without making it bulky under a jacket. I've washed it a handful of times and the two layers haven't shifted or pilled at all.
