Build your layers. Adapt to the day.

Lightweight tees, long sleeves and hoodies form the first part of your clothing system. Wear a piece on its own in mild conditions, or under a warmer layer as the day changes.

Choose the sleeve length, neckline and fit that feel comfortable with the rest of your clothing.

Pullovers, hoodies and vests add a flexible layer between a light top and your outer clothing. Choose sleeves for more coverage, or a vest when you prefer to leave your arms free.

Fleece and lightweight vest options sit in this group. Select the construction that suits your pace and the layers you already have.

An insulating vest adds warmth around your torso without another set of sleeves. The RM10 combines quilted insulation with an electric heating system.

Choose its fit around your intended layers, and check the product page for power requirements and operating instructions.

This group brings together fleece-lined jackets and outer pants. Match a jacket and pant to the coverage you want, with room for the lighter clothing beneath.

Construction and weather protection vary by style. Use each product page to compare the fabric and features that matter for your trip.

Rain jackets, pants, suits and ponchos provide different ways to add an outer rain layer. Choose a separate shell, a coordinated suit or broader poncho coverage to suit your setup.

Check each style for its material, seam construction and stated rain protection. Allow room for the layers you expect to wear underneath.
