Seifur - Icelandic Sweater - Ash/Blue

Q: Which size should I choose?

Lay a sweater that already fits you well flat and measure straight across the chest just under the arms, then match that number to the chest width column in the size table. Seifur is cut like Kátir Karlar and a little closer than our three-strand men's sweaters: size L is 54 cm (21.3 in) across, where Fennrir in L is 57 cm (22.4 in). We cannot alter a sweater, so pick the nearest size.

Q: Two strands or three: which should I choose?

Seifur is knitted from two strands of Plötulopi, so it is thinner and lighter than our three-strand sweaters such as Fennrir or Máni, and easier to wear under a coat or on a milder day. If you want the thickest possible sweater for standing still in deep cold, choose a three-strand one.

Q: How does it feel to wear?

Light for a wool sweater, with the dry, springy feel of Icelandic wool. A lopapeysa is worn over a shirt or a long-sleeved top, the way Icelanders wear theirs. One owner writes that the knitting was perfect and that she is thrilled with it.

Q: How do I wash it?

By hand, in lukewarm water, with a mild wool soap such as Lopisápa. Swish it gently without rubbing or twisting, rinse in lukewarm water, press the water out without wringing, and lay it flat on a towel to dry away from direct heat and sun. Store it folded, somewhere cool and dry, and not in a plastic bag.

Q: Can I exchange it if the size is wrong?

Yes. An unworn sweater in its original condition can be exchanged for another size under our return policy, linked at the foot of every page. Return postage is yours to pay unless the sweater is faulty or the mistake is ours.

Hand-knitted lopapeysa · 2-ply Plötulopi · Light ash grey with a white and blue diamond yoke

$456.00

Seifur is the Icelandic name for Zeus. It is our grey and blue version of Kátir Karlar, knitted from two strands instead of three: a men's sweater for someone who wants real Icelandic wool a step lighter than our thickest ones.

Seifur, in short

Light ash grey body with a yoke of diamonds in white and two blues, arctic and winter blue, finished with a row of small blue figures
Hem and cuffs carry a small white and blue pattern of their own over blue ribbing, not a repeat of the yoke
Two strands of unspun Plötulopi knitted as one, so it is warm without the bulk of our three-strand sweaters
Hand-knitted in Iceland in men's sizes XS to 2XL; the measurements for each size are in the size table

Care

Hand Washing: Icelandic wool sweaters should be hand-washed in lukewarm water using a mild detergent that's suitable for wool; Lopasápa
Avoid Agitation: Gently swish the sweater in the water without rubbing or twisting it, as wool is susceptible to damage when wet.
Rinsing: Thoroughly rinse the sweater in lukewarm water until all soap residue is removed.
Drying: Press out excess water without wringing, and lay the sweater flat on a towel to air dry. Avoid hanging or exposing it to direct heat or sunlight.
Storage: Store the wool sweater in a dry and cool place, preferably folded. Avoid using plastic bags, as they can trap moisture and cause damage. More info

Why you'll love it

Kátir Karlar in grey and blueSeifur is knitted to the same pattern and cut as Kátir Karlar, one of our most popular men's sweaters, in a cooler set of colours: pale ash grey with white and two blues instead of oatmeal with brown and black.
Unspun wool, knitted straight from the platePlötulopi is pencil roving, not spun yarn. Ístex says garments knitted from two or three strands of it come out exceptionally light and airy, and surprisingly strong once knitted.
Four shades from one colour cardLight Ash Heather, White, Arctic Blue Heather and Winter Blue Heather are all shades from Ístex's Plötulopi card, so the next Seifur is knitted in the same four colours as this one.
Allowed to be called an Icelandic lopapeysaThe name has been protected in Iceland since 2020. It may only be used for a sweater hand-knitted in Iceland, in the round and without seams, from new Icelandic lopi wool, with a patterned round yoke. Seifur meets each point.
Ready-made and sold from stockEach Seifur is knitted and finished before it is listed. Order on a weekday before 14:00 UTC and we dispatch it the same day.
