nice color and fit
I bought the Laurel Green Large Fit: Fit as expected. The large is a nice fit for me at 5'4" and 140-145 lbs (depending on the week). I prefer a loose or relaxed fit rather than form-fitting/slim and that's what I have in the large. It doesn't hang or billow, sleeves don't go down too far, but it moves nicely and is quite comfortable. Feel: the fabric feels nice on the skin and is cool on the skin as well. We're in the lowe 40s here now, so hard to say how it will feel in the summer. The fabric itself will feel cool but breathability in muggy summer will have to wait to test Look: the laurel green is a very nice, very pleasant subtle color which I like a lot. I also like the little design touches--the cuffed sleeves, the covered buttons. It has some weight to it so it hangs nicely and the weight combined with fabric makes it less prone to wrinkles quality: all looks good. Clean crisp design, not mis-aligned stitching, frayed/hanging threads, etc. Buttons all button cleanly. Very pleased

Quality, warmth and style
Size: 13 Women/12 Men, Color: Black
Bought these for my husband and he loves them. True to size and keep feet warm in the WNY winter weather. They are a great boot due to durability and ability to slip on and off.
