My Thoughts on the Arc’Teryx Alpha Parka Review

This coat is warm and expensive. This parka is designed for covering up in the cold while belaying a partner. It’s oversized, I’m wearing a medium in the pictures and video below. This allows for easy layering and maneuverability when wearing a harness. The parka also has added protection with Hadron™ fabric to reduce abrasions.

My favorite feature about the Alpha Parka is just how warm it is. I’ve used a half dozen warm-rated coats and parkas in the past, which has been the warmest-to-weight ratio I’ve used. If you are someone that gets cold easily and needs a way to quickly warm up this coat works well for other activities other than just belaying.

Arc’teryx using built this coat with an oversized hood, and a high collar for ultimate warmth. It’s also very breathable
