the model you are looking for is the Loki, made with plötulopi, feels soft and is rather light. makes a nice, warm sweater one can wear on all sorts of occasions. better for more moderate climates than the álafoss lopi, used for thick, rather harsh working or hiking sweaters.
when ordering this one, you can alter the colours if you wish
hands down best option is: go to Iceland, drive up to Álafoss and pick the one you like in the shop next to the foss. cool place to be! and interesting buildings in the neighbourhood
