Least favorite fabric when it arrived as it’s a little heavy feeling..almost like it’s half linen/stiff. As I wore it though, I started to feel really comfortable and now - as a casual shirt - it’s a fave

Richard M. (Hopewell, NJ)

Right out of the box, it is pretty much the perfect shirt

N B. (Houston, TX)

Nice, breathable casual material that wears pretty well through a day.

Taylor Z. (Lawrence, KS)

Overall a nice fabric. Not my personal favorite because the linen makes it a bit uncomfortable to wear for long periods of time.

Daniel R. (Redondo Beach, CA)

This fabric has nice weight and weave. The pattern has a scale to it I like. Unfortunately, the fabric does not feel comfortable when worn.

We named the Boulder Check after one of Colorado's most beloved roaring waterfalls, right in the heart of Denver's more mountainous sister city. In cool and breezy navy cotton linen with a clean box check, this is a relaxed classic that will keep you looking summer-sharp.
