Goðafoss is my favorite waterfall in Iceland. It's located up north, between Myvatn and Akureyri, and we were so excited to see it since the eruption of the Bárðarbunga Volcano closed off many roads to other attractions -- like the Dettifoss waterfall.
Anyway, this outfit was pretty much on repeat throughout the trip and kept me very warm. In colder conditions, I basically added this Aether jacket, some Arcteryx gloves, and a beanie to complete my adventure uniform. The weather changes very quickly in Iceland, so it's useful to dress in layers and be prepared for strong winds or rain.
