I think they’re worth a try…
Size: X-Large, Color: Bluish Blue/White Stripe
Final determination will take a few months of wearing the shirts.
First impressions,
1. styling is great. They look good.
2. When you l wash them, I suggest drying them all the way. They seem to wrinkle easier than other shirts I have.
3. Moisture wicking: on the few days where the weather has been warm, the shirt's seem to absorb the moisture from heat.
4. Fit: From my perspective I think the shirts are more of an athletic or modern fit, meaning a little more snug compared to other XL shirts I wear from Peter Millar or Footjoy or Fairway and Greene. I have broader shoulders.
Quality: so far they seem ok. I’ve notice on a couple of shirts I needed to cut or trim loose threads from manufacturing process. The fabric seems good with a decent amount of stretch built into the design.
Pricing: when you shop for big name brand golf shirts you pay a premium so these shirts, at around $30 a shirt, seem worth a try…I bought 5 different shirts so I’m hoping they prove to be worth it…

Comfortable and stylish
Size: X-Large, Color: Dark Blue Stripe
The shirt fits, stretches, doesn't wrinkle, and most importantly to me for a moisture wicking shirt, doesn't easily catch on things you brush up against and get little pulls in the fabric.

Great golf shirt!
Size: Small, Color: White/Light Blue Stripe
My son loves this shirt! It has silky smooth wrinkle-fabric and is nice and cool on the golf course. It is true to size, hangs well (no clinging) and allows full range of movement. It washes great! I wash and dry in the machine and stains come right out.

Beautiful colors, nice golf shirt
Size: XX-Large, Color: Aqua Blue Stripe
I always read reviews before I purchase and this golf shirt had positive ones. I ordered one so I could see the fit (true to size), and see how it laundered. Both are a thumbs up from me. Beautiful vibrant color, at a price comparable or less than what you might find in store. The SPF protection is a plus. I will be ordering more.
