23,403 ads from 9 undershirt brands in the Meta Ad Library, 2,190 running now.
9 undershirt brands have 23,403 ads in the Meta Ad Library between them, and 2,190 of those were running when we read it on October 23, 2026. Below is a page of creative from each, what formats carry the category, and how long the ads that work stay up.
Undershirt is a problem-solving buy, so the ads say what the old one gets wrong, bunching, bulk, sweat, show it vanishing under a dress shirt, and sweeten it with free shipping or a creator saying where to get theirs.
The library count is everything a brand has published on Meta. The active count is what was delivering at the read. The ratio between them is the account’s posture: a large library with a small active share is a brand cycling hard, and one where nearly everything is live is running a small curated set.

The scroll decides in a second or two, so the product goes in the first frame, in someone's hand or on someone's body, not after an intro. Video leads in this category.
