Jacquard knitted underwear sweater in Bula's iconic geo pattern. Made of 100% super fine Merino wool. Wool has temperature-correcting properties and good breathability. Wool is also a more environmentally friendly alternative as you do not have to wash the garment as often, just air it outdoors and it's ready to be used again. Thin, elastic seams prevent friction against the skin and raglan sleeves ensure extra good freedom of movement. Perfect both for winter skiing and for other outdoor activities.
