Wear it on your neck, as a headband, as a scarf (or snood), as a face mask, pulled up as a beanie to keep your head and ears warm, under your helmet or as a sweatband, the Altitude Merino Neck Warmer is the perfect adventure accessory.

Designed to fit comfortably within other ioMerino layers, the Neck Warmer covers the exposed areas of your neck while still having enough length to pull up over your chin and lower face, and covering the back of your neck when tucked into helmets and beanies.

Whatever you call it, neck warmer, neck gaiter, neck tube or head-neck-warmer-thingy, they’re a must-have accessory for your adventures.

Tag-free and flatlock stitching help eliminate chafe and maximize comfort. The anti-freeze properties of MicroMerino® prevent condensation build up on the Neck Warmer and stop it from freezing, and the antimicrobial properties mean it’s anti-odour.

Tower Trail exclusive, limited edition print. Print to order.

Andrea G (Melbourne, AU)
Trendy neck attire

Lightweight, super comfortable & warm. Looks great a definite for the winter wardrobe out walking!

mark wilson (Sydney, AU)
Essential item

My neck warmer is great for long afternoon walks along the coastline in cold windy conditions. Sometimes used to keep my ears warm. As the weather warms up I keep it doubled up on my wrist so it’s there if the weather changes. Great size and colour.

Richo (Adelaide, AU)
One is not enough!

I purchased this excellent product as a neck warmer for cold starts bushwalking, camping or outside near the fire at night. I am now wearing it as a face warmer, a headband, an ear warmer, a beanie and when overheating - as a sweatband. Last night I looked at other colours as I am sure owning only 1 is not enough. A universal, small item to be listed as essential packing for camping, bushwalking, fishing etc.

Love ‘Em

We love our soft warm neck warmers. Bought one for all of us - even our 3 young boys and their grandparents.
Perfect for our chilly winters down south

Warm and pretty

This neck warmer is soft and light, I forget I'm wearing it. Adds a pop of colour (raspberry) to my jumpers and tops.


Fabric Guide

While Merino is an amazing natural fibre, not all Merino fabrics are created equal. At ioMerino, we make our own fabrics, using only the best quality fibres, and to very specific specifications that make the most of the natural benefits of Merino. All of them are 'Merino rich’. No cheap blends passed off as Merino. No cheaper scratchy fibres or synthetic substitutes to save money. No unethical production. And each fabric is made for a specific purpose. So if you see something with a small amount of elastase or nylon added, you can be sure it absolutely needs to be there to enhance the natural stretch and durability. 

It took every bit of our 140 years of experience in the wool industry to perfect our fabrics, but we think you’ll agree the end result was more than worth the effort.

Ethically Made. Ethically Sourced. Perfectly Natural.
