I've been testing out the 1/2/3 Pack Shaper Slimming Tank Top for a few weeks now, and here's my honest take.

The Good: The compression is no joke! Wearing this under a fitted shirt instantly gave me a more toned silhouette. I wore it to a wedding and got compliments on my 'gym progress' (little did they know). The fabric is surprisingly breathable during workouts - no swampy feeling even after basketball sessions.

The Not-So-Good: Like one reviewer mentioned, the sizing can be tricky. I'm 5'11", 180lbs and the Large fits perfectly, but my buddy who's 5'8" needed to size up. The first wear feels like wrestling into a wetsuit, but it does loosen up slightly with time.

Pro Tip: Turn it inside out before washing to prevent rolling at the hem. I made that mistake once and spent 10 minutes flattening it out post-laundry.

Would I buy again? Absolutely - but only during sales. At full price, I'd expect slightly better stitching around the armholes.
