Seams appear a little weak - Compass 360 Mens RainTek Waterproof Camo Bucket Hat

I just received this hat in the mail. I usually have problems with “one size” hats but the fit is good. I am sure this is very waterproof but not sure of its ability to breath, yet to be tested. The only obvious flaw is the seam at the rear of the hat appears to be splitting. It is certainly useable but may need some attention later.
