Okay, so I decided to try these 'invisible' pull-ups after seeing mixed reviews. Here's my take:

First off, the comfort is legit. They really do feel like regular underwear and disappear under clothes. The absorbency is impressive too – handled a full workday without issues.

BUT... sizing is weird. I normally wear Large in other brands, but these ran small. Had to exchange for XL. The stretchy sides help, but if you're between sizes, definitely size up.

The odor control works better than expected! No embarrassing smells during long meetings. Skin stayed dry too – no irritation even after 12+ hours.

My husband tried them and loved how they didn't bunch up like some brands do. Says they're way more comfortable than his usual ones.

Downside? They're not as 'invisible' as advertised with tight pants. You can kinda see the outline if someone's really looking (but who stares at people's butts that hard anyway?).

Final verdict: Great for everyday use if you get the sizing right. Would recommend trying a small pack first before committing to bulk orders.
