Dubinik flannel Aztec heavyweight shirt
This is an example of simple and well organised shop with a lot of different and great designs. If you get your sizing right there will be no problem. I ordered XL (I am a larger guy, 191cm tall, 110kg, 117cm chest) and it fit perfectly, at first it was a bit loose but not too much, and after first wash it shrunk a little and then it was perfect fit. Even if it didn't shrink it would be fine enough to wear. Delivery was as expected. 2.5 weeks. Quality seems good and pricing is appropriate for that tipe of flannel, I will order more.
