I’m 5’9” 135lbs with broad shoulders and typically take a small or medium. My medium is very roomy with long sleeves and looks great tucked in. The shoulders are very dropped, more than I expected from the photos, but it makes it surprisingly modern. A small would have worked too, so size down if you’re between sizes.
Material is a little heavier and scratcher than other merinos I’ve bought, but I’m hoping it will be more durable than other brands and won’t pill so much. Overall I’m very happy with this and looking forward to seeing more Tilley clothing.
One final detail: there’s a little T logo in matching thread on the left just below the rib cage that’s an odd choice, would prefer to not have it but it’s pretty hidden. At first I thought it was some loose thread 😅
