Untreated polyester fleece will develop noticeable odor after one day of active skiing, so wearing it for a full week without washing is not recommended. For multi-day trips, either pack two balaclavas to alternate, choose an antimicrobial-treated fleece model that can go 2–3 days between washes, or consider a merino wool balaclava which offers natural odor resistance for extended wear. Washing your fleece balaclava in the sink with mild soap and hanging it to dry overnight is practical since fleece dries quickly.
