How does the Z-4 shell jacket fit, and what size should I choose?

The Z-4 has a comfortable, ergonomic fit with stretch fabric for easy movement. It is a unisex jacket based on men's sizing. For women, consider sizing down for a closer fit. Refer to the size chart for guidance.

Is the Z-4 suitable for both resort and backcountry skiing?

Yes, the Z-4 is designed for active use on groomed runs and in backcountry terrain. Its 3-layer ALP-3 ripstop fabric provides reliable protection and breathability in changing mountain conditions.

Can I wear the Z-4 for hiking or everyday outdoor activities?

The Z-4 shell jacket works well for hiking, travel, and city use thanks to its minimalist design, weatherproof construction, and versatile features.

How should I care for and wash the Z-4 shell jacket?

Wash the jacket inside out in cold water (up to 40°C) with mild detergent. Close all fasteners before washing. Tumble dry at low heat and avoid bleach, fabric softener, or dry cleaning.

Does the Z-4 shell jacket offer protection in harsh weather?

The Z-4 is waterproof, windproof, and highly breathable, with a helmet-compatible hood and snow skirt for added protection during cold, wet, or windy conditions.

Is the Z-4 available in multiple colors?

Yes, the Z-4 comes in Black Onyx and Kelp. Both options share the same technical build and clean, modern look.

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.
