I bought a t-shirt of Mast and Harbour from a leading online store.
The t-shirt quality is very good, the cloth is thick as per my expectation and is also very soft.
But the fitting.
These new brands generally make very small t-shirts in length but otherwise fine, so you can’t even take a bigger size because that is loose on the chest and shoulders. Generally L size fits me for almost every brand but their L size only reached the belt, it was that small in length.
Overall, if it fits you okay, the quality and value for money is really good.
