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.

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.

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.
Perfect for work in warehouse, want more.
Perfect base layer or worn alone.
