Kinflyte Unity V-TOP
Putting on the Kinflyte Unity V-TOP ($150) on a humid day required a bit of finessing since the compression combined with the slickness of the fabric made it a little more difficult than sliding on a regular T-shirt. I folded the shirt about two-thirds of the way so I could slide it on like a sports bra, then unfolded the rest over my torso.
On the outside you can see that from the front, side, and back, this top has me covered, but under this top there are details that add to that feeling of security. Under the shoulders there are polyurethane panels that prevent the top from sliding around, helping to maintain consistent back support. There are removable cups so (if you're like me and don't like cups in tops) you can remove the cups and still have adequate support. The fabric contains UPF 50 meaning your skin will be protected from the sun wherever the fabric coats your skin.
Bonus: This top has a decent sized pocket on the left side so you can keep your essentials by your side at all times.
