This is the sweater you reach for when it is grey and drizzly, when you want warmth without weight, and when a shirt underneath is doing half of the outfit's work. Seaglass sits in that useful middle green range, quiet enough to layer over an oxford or under an overshirt, and warm enough to hold up on its own with five-pocket cords or raw denim.
100% Pure New Wool, knit in Peterhead, Scotland. The hand is soft with real body, a medium-weight sweater with the textured shaggy surface that gives this style its name. This is Harley of Scotland's iconic Shaggy Dog crew. Harley knits this same body for a lot of the American heritage brands you already know, so the sweater has a lineage that runs through several labels; when you buy the Harley-branded version, you are buying the source.
Seaglass reads as a muted green with the softness of glass worn smooth by the tide. Coastal, quiet, and easy to pair with navy, grey, cream, tobacco, or washed indigo. It suits the wardrobe that leans on knitwear from October through April and wants a green that feels considered rather than loud, the kind of piece you keep pulling for another decade.
