You can be sure

We know it's important to choose the right t-shirt size to look great. It is easy with our size-guide. Just choose what is the best for you:

  • I don't need any help and I know my size - I can just check the size chart (I can find it under this text) to be sure and then pick up my t-shirt.
  • I don't know my size - I'll check size of my older t-shirts first. Then I'll check, how I am build and check the size chart. If I still don't know, I can call to guys from phone +420 245 009 025 or just send them an email to and they are going to help me.
  • I need a help - I will call to guys from - phone +420 245 009 025 or just send them an email to and they are going to help me.


How am I build?

  • I'm thinner than most of other guys - I'm going to enjoy the Vintage tri-blend t-shirts and I can also waer Athletic fit t-shirts easily. They're made for me.
  • I'm medium build, like most of guys - Athletic fit t-shirts are made right for me. They're going to do my body better and I can easily show off what needs to be shown thanks to them. I don't neccessarily be "the muscle guy" to show my muscles better.
  • I'm a really big guy - I've grown up more than other guys (it doesn't matter if that is because of nature, intensive workout or just because of good food). I enjoy Regular fit t-hirts the best. They're made up to 3XL size.
