Mammut Women's Beanies

Frequently Asked Questions

• How does a fine-knit merino beanie compare to a fleece‑lined chunky beanie for mountain use?

  A fine-knit merino beanie is lightweight, breathable, and better at managing moisture during high-exertion activities like ski touring or fast hiking, making it easier to layer under a helmet. A fleece‑lined chunky beanie provides superior passive insulation for slow-paced outings, apres, and very cold conditions but can be bulkier under helmets. Choose the fine-knit for aerobic mountain days and the fleece-chunky option for casual cold-weather warmth.
• Will a Mammut beanie fit under my climbing or ski helmet and what about sizing?

  Most Mammut women's beanies are one-size-fits-most and are designed with low-profile constructions specifically to sit comfortably under helmets for climbing, mountaineering, and skiing. Fine plain-knit or fine-mesh styles are the best bets for helmet compatibility, while chunky knits or bobble designs may feel snug or create extra bulk. If you plan to wear it under a hard shell, pick lighter, lower-volume models and check weight/bulk descriptions.
• How should I care for my Mammut beanie to maintain shape and performance?

  Hand wash your beanie at 30°C or lower using a mild detergent, avoid bleach and do not dry clean or tumble dry to prevent felting and loss of loft. Gently reshape and lay flat to dry, and if ironing is necessary use a low setting (max 110°C) without steam. Regular gentle care preserves the knit structure, fleece lining, and any wool properties like odor resistance.
