I purchased the Brixton Men's Busker Hat in Olive Twill. I'm awarding 5-stars, but sizing needs to be more accurate. Will get to that...

First, I don't always rely on the visualization of color on a computer screen. For that reason I was not disappointed in my hat that is actually more of a green/dark khaki color. The image here is a much lighter khaki and does not appear greenish at all. But the color description does say OLIVE, so now you know. I am happy with the color.

Second, sizing. I measured my head with a standard sewing fabric tape measure and looked up my size on the sizing link. According to that chart I should be smack in the middle of a medium. However, I checked some of my other hats and ordered a size small. The small arrived and fits my head PERFECTLY. Had I ordered a medium, it would have been, no doubt, huge on my head. So be aware that this could mean possible returns for size.

Third, construction. The Busker Hat is very well constructed. There are no unfinished exposed surfaces or seams and there were no odd threads hanging around waiting to be trimmed clean. It is a high quality hat that will last a long time.

With this type of fabric you can wet it down, "shape" it and let it air dry for a crisp firm look. Or you can wear it with a more crushed appearance. It is sturdy enough to endure a washing machine, but I prefer to wash certain hats in my dishwasher. Don't laugh, it works great. For ballcap style hats, you can even buy a special cage to hold the ballcap in a specific shape while in the dishwasher and for drying.

This is a very nice hat to add to my small (but growing) collection. In fact, I'm going to order the same style in Black Herringbone too.

EDIT: I love these Brixton hats. Since my initial review of the Olive Twill I have in fact purchased the Busker hat in Black. I love it and it has won favorable comments from my circle of friends. As originally reviewed, I measured my head and that measurement said to order a Medium. Based of previous hat experience, including Buxton, I opted for the Small and I was right. A medium would have been loose and flown off in the slightest breeze. The small fits me perfect - not tight, not loose.

For hats that are a cotton based structure here is a fitting trick... If the hat is too loose, soak the hat in a sink full of HOT water. Drain on a non-staining surface. (You don't want a light color hat to "pull" color from another surface, and you don't want a surface to be stained by any color that might bleed off a dark fabric hat.) As the hat dries, 'form' it with your hands into the shape you want and put it on your head to check the fit. The hot water should have helped to tighten it up.

If the hat is too tight, again soak the hat in a sink of COLD water. Drain as above and then stretch the hat onto your head forcing the band to adjust to your head. Wear the wet/damp hat until it dries. (Makes for a fun evening of TV watching.)

Good luck.
