Have an Arcteryx short sleeve button up shirt that was $75-ish but I’d say is “worth it” because of the unusual pattern(hidden double chest pockets.) Haven’t tried a Skyline but they look great in ‘fit pics.
Received this piece a few days ago and really like the fit. It's described as "regular" fit while the shirt linked above is "trim." Not sure how much slimmer that is. I think the poly/wool blend is interesting. Worst case I can buy/return from Amazon.
EDIT: Manufacturer website lists the A2B short sleeve as a poly/cotton/elastane blend. Less interesting.
