SeattleBernerwrote a review of Outdoor Research Sequence Zip-Neck Top - Men's on December 3, 2014
Familiarity: I've used it several times
Fit: True to size
Outdoor Research is one of my favorite gear companies. They make solid gear that is functional without excessive add-on's that are fluff.
This base layer is simple, well constructed, and performs well. The merino wool blend functions as expected by being soft against the skin, wicks moisture, and doesn't stank!
I am 6'1 180 lbs with long arms and the Large fits great. It is a bit snug around the forearms and zipping it up all the way is pretty snug around the neck, so keep that in mind.
