Review on Men'S UPF 50+ Quick Dry Compression Shirts: TSLA 1-3 Pack For Athletic Workouts & Water Sports by Jason Yancy

UPDATE: I went ahead and ordered a 3-pack Black MUB20 size SMALL because the stitching locations in sample image looked more like the MUB23 (Athletic) I had previous experience with. SMALL gives the compression I was expecting (or more) compared to the MEDIUM MUB33 (Active) which was far too loose. SMALL is quite tight but not suffocating to wear all day long. A little hard to pull across my back when getting dressed but I'm not as flexible as I once was.-----------------------I'm 5'7" 180 lbs. typically size Large in most shirts. I've purchased several MUB23 (87% polyester,13% polyurethane) in Medium-Large over 3-4 years for wicking and flattening man boobs and belly so appearance in flimsy cotton work uniform won't offend. Those were true-to-size and had snug compression but discontinued. I've since lost 8-10 lbs. mostly in love handles and thighs but went ahead and bought two MUB33 (87% polyester,13% elastane) size Medium based on reviews. Fits larger than MUB23 and VERY loose compression. Will be attempting to exchange for Small or refund the package I haven't yet opened and reluctantly shop alternative brands.Because this is a review to be fair I should mention that other than the fit of this MUB33 style, I have loved the Tesla shirts compared to the competitors. They hold their compression longer after many washings and light drying. The extra length is great for not pulling out of pant waist, even if you have some belly like me. The fabric and features work as advertised. The stitching is great and holds up better than the competition. The neckline is just right and comfortable. I just wish they hadn't discontinued the MUB23.
