The Icebreaker Oasis re-entered the competition in our latest Men's Long Underwear Review. We couldn't resist getting our skin wrapped up in this comfortable merino wool fabric once more. On top of great comfort, this shirt also breathes exceptionally well and is relatively quick to dry. Throughout the testing period, though, our patience with the sleeves of this model became similar to this fabric — thin. They were constantly riding up our arms and camping out there until we pulled them back down. When cold air hit our bellies, we were reminded of this model's short torso, too. It's also not as versatile in layering combinations as several other products we tested. Our opinion of this product is still pretty high, but its score wasn't enough to snag any awards.
Since we reviewed this top, Icebreaker replaced a few color options for the Oasis. The bright blue colorway we tested is no more, replaced by the dark blue option pictured above. Performance-wise, this top remains unchanged.
