★★★★★
The Midnight shirt is unbelievably soft and breathable, and knowing it's actually lab tested for toxins makes it feel like a real upgrade from regular cotton tees.
Devin R. Verified Buyer
★★★★☆
Great quality shirt and the fit is flattering. Just be aware it ships in batches, so mine took a few weeks longer than a typical online order.

Fabric feels great, but I noticed a bit of shrinkage after the first wash even following the care instructions.
