I have/had both. The aerolight I didn't feel was warm enough, and it was loud. The Kenai is better as a midlayer under a windproof shell for stationary use, but it's really quiet. Neither one of these are going to be your go to for glassing, you'd want something more substantial.Wondering how these jackets compare in warmth and wind resistance in stationary use?
Has anyone used both to be able to compare them?
