FAQ
Frequently Asked Questions
Is merino wool too warm to wear in September?
Merino wool is a natural material that absorbs moisture and releases it away from the body, helping regulate the climate inside your clothing. While the weather is still warm, wear a short-sleeve piece on its own. In cooler mornings and evenings or air-conditioned rooms, add a cardigan or stole.
Which combinations qualify for 15% off?
The discount applies when you purchase 1 item from Group A and 1 item from Group B together. Two items from Group A only or two items from Group B only are not eligible.
Is the discount applied automatically?
Select an eligible Group A and Group B combination on the dedicated Bundler purchase page and add it to your cart to receive the campaign price. Before publishing, place a test order in the live store and confirm that the discount is displayed correctly.
Can I wash these items at home?
Follow the care label and washing instructions listed on each product page. We recommend using a laundry net and mild detergent, then reshaping the garment before air-drying.
Can I choose a different size and color for each item?
Yes. On the dedicated selection page, you can choose the color and size of each item individually. Sold-out variations cannot be selected.
