Good buy
Was looking around at a few cheaper options but landed on this one, in the end, and bought three. Don't regret my choice at all. Perfect for wearing under a shirt/suit, working nights in the winter. Really nice feeling material. I wouldn't recommend wearing just this out in the cold but it has thermal qualities, whilst remaining breathable. Comfortable, fits well and well priced for the quality

Excellent buy
Have had this for some time now and still enjoying the softness even after many washes. Very good quality

Comfy
⭐️⭐️⭐️⭐️ – Comfortable and Warm, But Not True Compression This top is really comfortable and does a good job at keeping you warm during workouts or as a base layer. The fabric feels high-quality and it’s breathable enough for both training and casual wear. However, despite the appearance, it’s not a true compression shirt — it fits a bit looser than expected. If you’re looking for that tight, muscle-hugging fit, this might not be it. That said, it still performs well and feels great on the skin. Solid choice overall.

Perfect for my running
I bought this for running in the cooler months and it works perfectly for that, not too hot but warm enough. It’s very comfortable and fits well, long enough so it doesn’t ride up. I’ll probably need another because it gets worn so often and washed so much.

Great top at a great price. Perfect base layer for winter football. Delivery was quick, thank you.

To small, size up x2
Come up way to tight. I'd say two sizes to small. But good quality still, nice thick silky fabric

Well designed and great fit for me
I think this long-sleeve shirt is excellent for my running needs. When the sun's radiation is high, I prefer to sweat a bit more to keep my skin protected. Since I don't enjoy using sunscreen while running, this shirt is very handy. The quality is great, and the fit is exactly as I wanted. I am 183 cm tall, weigh 72 kg, and ordered the size M.

Comfortable and protected
Got this for Saturday noon Pickleball games in the Sun. Been getting sunburnt and sweaty in my tshirts. With this long sleeve shirt and a cap I don’t need to apply sunscreen on my arms. Material is a good medium weight that is not too thin but still cool and wicks away sweat. I normally wear a large shirt which is right on my shoulders and loose on the sides ( I’m pretty thin). For dry fit I order one size smaller. A medium in this shirt fit me perfectly. Only problem I have is that this shirt keeps ending up being taken by my adult boys. I will definitely be buying more. Only wish it were slightly cheaper and came in more colors.
