Hello, thank you for your inquiry into our Supima Cotton Non-Iron Regular Fit Multi Fun Stripe Sport Shirt. Unfortunately, our sport shirts are not offered in Extra-Slim fit, only our dress shirts. However, for a similar fit, might we suggest our Red Fleece line of offerings? When you proceed to the men's sport shirt page, you will still refine your search in the left-hand navigation to Extra-Slim Fit, but the Red Fleece items will appear instead. There are many styles and you will still choose the size which you would ordinarily choose for a mainline sport shirt.

We do hope this information is helpful in your selection.
Kind regards,
Brooks Brothers
