I am a medium in everything I own from Mons and really love their gear and this piece but it fits like a second skin. Armpits are cut high and it’s glued to you like a base layer rather than bike jersey. Size up and prolly be stoked.
The temple marino t is part of a suit of Mons products I love and use. A great base layer in colder conditions or On it’s own in the heat. Specifically used every day on 5 day trek. Thoroughly recommend.
