Named after Archaeopteryx lithographica, the first reptile to develop the feather for flight, the ethos of Arc’teryx is all about problem-solving. Perfect for the outdoors, the Beta Jacket is crafted with GORE-TEX® material and GORE C-KNIT™ backing. Providing waterproof and windproof protection with enhanced breathability, a trim fit allows for light layers underneath whilst allowing unrestricted movement.
