RUNS REALLY SMALL, ALSO VERY, VERY THIN. & I’M NOT A FAN OF THE MATERIAL. I RETURNED IT.

Very comfortable! The minimal information in the product description at the time of purchase made it a bit of a shot in the dark, but the jacket is super lightweight yet warm and breathable for those cooler weather runs. I never saw anything about this in the description, but there are slits in the built-in under sleeves that run over the hands for looking at your smartwatch without needing to pull out of the thumb hole and lift the whole sleeve up. Brilliant feature. The hood covers my head without leaving my face too exposed to the rain. There’s print inside the zip up chest pocket that says the jacket is packable, and while I haven’t tried, the jacket certainly feels lightweight enough to do so.
