Overall rating: 4.8 / 5 from 20 reviews.
A good quality heavy shirt, too warm for it at the moment though but come winter I can see it getting a lot of wear.
Store owner replied:
Thank you for the feedback! We’re glad you’re enjoying the quality and substantial feel. Hope it becomes a go-to piece once the colder weather arrives.
Olderbest has EXCELLENT customer service. There was a hiccup with the shirt that was sent out to me but Olderbest made it right.
They have a customer for life.
Can’t beat the quality of the shirt.
The fit is right on point. Super fast delivery.

Thank you for your feedback. We're so glad the product met your expectations. Your support means a lot to us.
Nice heavy weight long sleeve shirt, fits well, wouldve liked if the neck opening was a bit more slimmer or smaller as it seems a bit wide for my preference.
Store owner replied:
Thank you for your feedback. We’re glad to hear you’re happy with the fabric weight and fit, and we appreciate your note on the neckline—it’s been shared with our product team for consideration.
One of the few shirts ive worn that make me feel comfortable to wear and not worry how the waist will look, tight and loose enough to be perfectly comfy

Fantastic thick material. Fits like a glove. Already purchased another for winter

First wear feels really good. Hopefully it washes well
Great quality, thick cotton, good value for money. I had a query about sizing and they were very helpful and speedy in response. Great company to deal with.
Very fast service from Older Best . Customer service was next level. I was contacted before delivery to check on sizing. The quality of my top is without doubt comparable to the big name brands.Couldn’t ask for better. I will definitely be buying from here again.
