Dim Thermal レディース 長袖 コットン Tシャツ ブラック

I’ve worn this under sweaters all week and it’s discreet under everything, no bulking or bunching. The cotton feels breathable while still keeping my chest and arms warm on cold mornings, and the black hasn’t faded after two washes yet.

The cotton is thick enough to trap warmth without that clammy feeling, and it layers perfectly under a flannel for my morning commute. I've worn it three times this week and it's already my go-to winter base.

I was worried thermal shirts would feel stiff, but this one is actually soft and comfortable for all-day wear. The cotton keeps me warm without making me sweat, and the long sleeves work perfectly under sweaters. Definitely my new go-to for cold days.
