Love the Jacket, Sizing was Interesting

I love everything about this jacket. It's well built, material is superb, and I'm the talk of the TOC when I whip this puppy out on frosty mornings.

Figuring out the sizing was incredibly annoying. Using the sizing chart, I'm a size small but the small fit me like a tight latex kinksuit and the length (barely) covered my belt with my arms at my sides. Lifting my arms resulted in the bottom of the jacket raising above my belly button; ew. I'm 5'9", 165lbs, and by no means expected an adult jacket to be this short. Ordered a size Medium Long to solve both those problems and it now fits like a standard, trim fit, jacket.

Beyond needs to fix their sizing chart to reflect the VERY short nature of the jacket (add a length measurement or something) and you, the customer, need to purchase one of these jackets due to the VERY high quality nature of this jacket. Five star jacket, one star sizing chart, four stars overall.

I love this thing

Extremely comfortable warm and cozy BEYOND why I expected totally recommend!

Cole Herring

Great Jacket!! Used alongside midlayers the A3 can be worn comfortably when static even in low tems (0-15°F). When used alone with a wicking layer it can be used well as a kinetic layer depending on conditions.

Best outer wear I have.

This company makes the best stuff for the outdoors and the military 10/10

Ray Kinney

The warmth performance and weight of this garment is the most epic surprise and combo. Light weight and holds in heat like a champ. Used this in a field problem here in the service with temps in low 20’s (F). Would have given 5 stars but the collar is beginning to fray quickly. Will upload a pic here a bit later.

Would recommend and would buy this product again.
