First off, let’s talk fit. I usually wear a large, but after reading reviews, I sized up to an XL—best decision ever. The sleeves are snug (my arms aren’t huge, but if you’re packing serious muscle, consider sizing up twice). It hugs your torso like a second skin, instantly flattening my post-lunch belly. Pro tip: Check the size chart religiously!

The sweat factor? Unreal. I wore this during a 30-minute HIIT session and looked like I’d jumped in a pool. Unlike gross sticky cotton tees, the fabric traps heat while keeping the outside dry—no embarrassing pit stains mid-workout. My core stayed furnace-hot, especially around the waistband that grips like it’s personally offended by love handles.

Durability’s a mixed bag. After three washes (hand-washed and air-dried as instructed), mine still holds up fine, but I’ve seen reviews mentioning popped seams. For $30-ish, it’s worth rolling the dice—just don’t expect decade-long wear.

Bonus: Wore it under a hoodie for errands and secretly torched calories while grocery shopping. Instant confidence boost when your reflection looks sculpted even before hitting the gym.
