The Women's Altitude Crew Neck Base Layer is the perfect ‘go to’ thermal layer for just about any adventure and our all-time best seller.  It’s the perfect thermal layer for core warmth when you’re layering up, yet versatile enough to be worn on its own in milder conditions.

Tag-free, flatlock stitching and raglan sleeves help eliminate chafe and maximise comfort, and the drop back hem designed for tucking into your outer layers, or sitting over bottom layers, with no exposed cold spots when you're on the go. The thumb loops keep your hands warm and stop your sleeves riding and bunching under your arms when layering. This top is the perfect combination of performance, warmth and comfort.

Comfy, keeps you warm and washes well.

We bought this to wear on cold mornings for training on the water. It is comfy, keeps you warm, is lovely and soft and I don't over heat in it. Thumb holes are good and the length is good, it fits very well. The only down side is, it is very delicate. Mine has a hole in the knit after one wear but it is a knit so I guess to be expected if anything touches it.

Hi Carie, We have a one year warranty for all manufacturing faults, so please feel free to get in touch with us at customerservice@iomerino.com if you're having any problems.

Just an awesome top

I love this top and wear it everywhere - I have it in blue, and its my favourite color of all merino wear in the cupboard (and I have a fair bit on hand!). Beautifully warm, beautifully breathable. Genuinely smells like Woolmix when I run and sweat in it - doesn't seem to ever have an odor. Rarely need to wash because it airs out just as well. Stoked!

THAT EXTRA LAYER TO KEEP ME WARM

I am always cold thus always had to add extra layers and would still be cold. Now I only need this or add a Mongrel over the top and I am set.

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.
