James Blantonwrote a review of Arc'teryx Covert Fleece Hooded Jacket - Men's on January 12, 2012
I am 6'0 /180lbs athletic/runner build, the Covert is too short for me. The sleeves are about 1 to 1 1/2 inches too short and the waist falls right at the the belt line....dont raise your arms. If this item were to shrink in the wash, it would be unwearable.
Based on the measurements of the XL it is going to be very large in the body for me.
I have an Arc'teryx Gamma jacket in large and it fits perfectly. The Covert apparently is not cut to the same sizes as their jackets.
