How does the U-11 W fit, and should I size up or down?

The U-11 W has a close, women's base-layer fit designed to sit smoothly under outerwear. For a next-to-skin fit take your usual size; size up for a looser feel.

Merino wool regulates temperature and continues to insulate even when damp, making it a reliable base layer for cold days on the mountain.

Does it manage moisture and odour?

Yes. Merino wool is naturally breathable, quick drying, and anti-odour, helping regulate temperature through changing activity levels.

Can I wear it under a shell?

Yes. The close rib-knit fit layers smoothly under mid layers and outerwear, and has enough character to wear on its own in the right setting.

How should I care for the U-11 W?

Wash on a wool or delicate programme at 30 °C, inside out and separately, with a mild detergent. Do not tumble dry, bleach, or use fabric softener, and iron on low heat if needed.

How fast is delivery, and what does shipping cost?

Orders placed on weekdays before 12:00 CET (EU, Switzerland and Norway) are normally dispatched the same day. Delivery usually takes 1–2 business days in Sweden, 1–3 business days in the EU, Switzerland and Norway, and 2–5 business days for the rest of the world. Shipping costs and any free-shipping threshold for your country are shown before you pay. For our key markets, including the EU, Switzerland, Norway, the UK and the US, taxes and duties are already included in the price.

Can I return or exchange my order?

Yes. You can return unworn items with tags attached within 30 days of delivery through our return portal. Returns are free, except from Germany where a €5 fee is deducted from the refund. We don't offer direct exchanges, so if you need another size or colour, the quickest way is to place a new order and return the original.

Which payment methods can I use?

You can pay with major credit and debit cards, Klarna, digital wallets and, in many countries, PayPal. The available options are adapted to your country and always shown at checkout. All payments are encrypted and handled by our payment partners, and we never store your payment details.
