    Softer than cotton

    Bamboo viscose is known for its exceptional softness. Made from regenerated cellulose derived from bamboo, the fibre is smooth, lightweight and comfortable against the skin, with a gentle stretch that moves with you.

    Lightweight, breathable and soft against the skin, it's a natural choice for everyday comfort, especially in warmer weather and the seasons in between.

    Read All FAQs
    Do you have a size chart?

    Yes. Every product page includes a size guide with detailed measurements for that specific garment, along with a how-to-measure section so you can compare against a piece you already own. Sizing can vary slightly between styles, so we recommend checking the guide for the item you're looking at rather than assuming your usual size. If you're between sizes or unsure about fit, email sales@nznature.co.nz and our team will help you find the right one.
    I ordered the wrong size, can I exchange it?

    Yes. You can return an item for exchange within six months of the order date, provided it's unworn, unwashed and in its original condition with tags attached. Fill in the returns form enclosed with your order and send it back to us. Return postage is at your own cost, but we don't charge you postage to send the exchange item out. If the replacement is the same price, it's a straightforward swap. If the values differ, we refund your original payment method and recharge for the new item. If you're not sure which size to go for, email sales@nznature.co.nz with your order number and we'll help you work it out first.
    What is a multi-buy offer?

    Selected products are eligible for multi-buy savings. Purchase the qualifying quantity and the advertised discount will be applied automatically in your cart. Mix and match colours and sizes unless otherwise stated. Terms and exclusions may apply.
    Are your products made in New Zealand?

    Many are, and the product page tells you which. Anything made here carries an 'NZ Made' tag — that includes our Merino from Weft and Essence Lingerie, our sheepskin slippers and boots from EB Tolley and Furmoo, and skincare from Nude Kiwi.

    Some of our range is made offshore, and we're upfront about that. Silk and bamboo, for example, aren't fibres produced in New Zealand, so those garments are made overseas to our specification. We're a New Zealand company and we make here wherever we sensibly can.

    If you want to know the origin of a specific item, look for the NZ Made tag on the product page, or ask us and we'll tell you.
    Which base layer should I choose: silk, merino or bamboo?

    It comes down to what you want the layer to do.

    Silk is the lightest option and close to invisible under clothing. It adds genuine thermal warmth without any bulk, which makes it ideal under work clothes, under a shirt, or for travel. Choose silk when you want warmth nobody can see.

    Merino is the warmest and most hard-wearing. Our superfine and ultrafine Merino sits between 16.9 and 18 microns, so it feels soft rather than scratchy, and it's naturally odour-resistant and machine washable. It's the right choice for hiking, genuinely cold days, and everyday wear.

    Bamboo is soft, stretchy and breathable, and it's our most affordable range. It's better suited to everyday comfort and sleepwear than to serious warmth.

    Still unsure? Email sales@nznature.co.nz and tell us what you'll be wearing it for.
    How do I contact customer support?

    You can reach our team by emailing sales@nznature.co.nz or calling +64 3 9700 441 during business hours (Monday–Friday, 9am–5pm NZST). We also have a contact form on our website. We aim to respond to all enquiries within one business day.
