Just like polar bear fur, alpaca fibers are completely hollow, so it only takes a smidge to keep you toasty in Ol’ Man Winter’s worst. And if you’ve ever had the privilege of petting one (the alpaca – not the polar bear – we don’t recommend petting polar bears), you know just how soft and luxuriously smooth they are. We blended ours with classic sheep’s wool – choice fiber of fishermen the world over for its naturally temp-regulating and sweat-wicking properties. Topped off with a healthy dose of nylon for strength and recovery, this cardigan’s a true workhorse in sheep’s clothing. And sporting a geometric pattern that’s both timeless and right on trend, it’s a hardworking favorite you’ll don for years to come.
