Elevate your hiking adventures with the perfect combination of comfort, performance, and style—the Women’s Merino Hike T-Shirt. Made from 100% Ultrafine Australian Merino wool, this luxuriously soft t-shirt feels almost too good to wear on a hike. But once you try it, you’ll never go back to polyester.
Merino wool is an exceptional choice for every hike. Its breathable and moisture-wicking properties naturally regulate your body temperature, keeping you cool, dry, and comfortable in any weather—even the heat of summer. Plus, the fabric naturally shields against the sun with a UPF rating of 40 to 50+, blocking over 97.5% of harmful UV rays. This level of protection often surpasses many specialised sun-protective fabrics, all without synthetic fibres.
Designed with a relaxed, slightly boxy fit, the Women’s Merino Hike T-Shirt effortlessly blends style and function. Whether you're tackling rugged trails or catching up with friends, its classic high neckline protects delicate skin on your chest from harmful UV rays. The extra length helps prevent friction from your backpack, ensuring maximum comfort on the go.

Micron
Ever wondered why some Merino wool feels like a warm hug while others feel like a prickly cactus by lunchtime? It all comes down to the micron — the measurement of a wool fibre’s diameter. The smaller the number, the finer the fibre, and the softer it feels against your skin.
Not sure where to start? Use this guide to find the perfect softness, feel, and warmth that’s just right for you.
| Micron Category | Diameter (Microns) | Primary Market Use |
|---|---|---|
| Ultrafine Merino | 14.6µm – 16.5µm | High-end luxury apparel and knitwear |
| Superfine Merino | 15.1µm – 18.5µm | Suiting, premium base layers, and fine yarn |
| Fine Merino | 18.6µm – 20.5µm | General apparel, sportswear, and weaving |
| Medium Merino | 20.6µm – 24.5µm | Heavy knitwear, blankets, and carding wool |
| Strong Merino | 24.6µm+ | Furnishings and heavy-duty textiles |

Easy Care Guide
Easy Care Guide

- Machine wash 30° gentle/wool cycle
- Wash with similar colour wool garments
- Protect your garment by using a laundry bag
- Use wool or gentle detergent
- Do not use bleach, optical brighteners, enzymes or softeners (weakens yarn)
- Lightly reshape and lay flat to dry
- Use iron on wool/delicate setting (if at all)
- We recommend hanging your garments to air between wears. Merino wool is naturally antibacterial and odour-resistant, it doesn’t require washing after each wear.
