@Alex I bought it from Iron Hear America right before the holidays.

Increasing the button sizes might help a but but ultimately the button holes will stretch out due the nature of fabric.
They oughta reinforce the button placket to minimize stretching.

@Palmer:

The button issue is present in all of the lightweight Iron Heart button up shirts I own. Either the button size needs to increase or the hole needs to be smaller. Definitely a big bummer considering the price.

Yeah I agree, for that price this should not be an issue, especially not from a brand like Iron Heart that has a reputation of making sturdy over engineered garments.

Pretty major bummer to be honest.

Picked up one of these over the holidays for the hot California weather.
The shirt is bittersweet for me - the fabric and fit is great but the button placket is a major disappointment.
Wether it is due to the linen or the size of the buttonholes, the buttons just won't stay in place.
The holes become loose after a day and the shirt won't stay buttoned. 
Never had this issue with any of my IH shirts.
If the button placket were thicker or reinforced this wouldn't happen as far as I can tell.

@Giles:

Me too….

Yes, I am sure you get better with age too:)

Without a doubt one of my fav caps in my collection. They only get better with wear!

All good Davito, Thanks for your help!

Looking good Davito! How do you rate the fit compared to regular McCoy sweats?

@davito:

I wear a small in the heavy ballpark crewneck and heavy Ballpark zipup and small in IH heavy flannels. I ordered my usual small in this one. Will see how it turns out when it arrives.

@SepticSef

So would you suggest I wear XL then? I remember my IH sweatshirt always felt too big in XL but then again it wasn't double faced….

@Danny:

@SepticSef:

Thanks guys - glad you dig my work
And yes, Nate pointed me in Self Edge's direction 3 years ago where I  started my IH collection;)
The quality of TFH shirts is truly insane!

Good to meet you on my recent trip and love the hemming monster T shirt I picked up at SESF. It's our new uniform for hemming IH heavy denim.

Hahaha that is good to hear and great meeting you!
