Our Altitude range is designed to fit close to your body for maximum performance, so it’s tight but still soft, with plenty of give for extra comfort. The Men's Altitude Crew Neck Base Layer is the ‘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. The drop back hem and extra body length is designed for tucking into your outer layers. Thumb loops keep your hands warm and stop your sleeves riding up when layering.

This top is the perfect combination of performance, warmth and comfort.

(For a more relaxed fit try our Ultra or Universal tops.)

Ultra Trail Australia mandatory gear approved thermals.

Designed to be worn as a body tight ‘contact fit’ layer.

Get warm this winter

Two new tops are providing me with continuous comfort and warmth while l work from home. No itchiness whatsoever. Multi wear between washing. The tops are a very solid base from which to start your clothing layering.

First purchase

I purchased an Ultra Zip, an Altitude long sleeve crew and a skull cap. I am generally between Medium & Large. In these styles for me at least - Medium is plenty big enough. The Ultra Zip fancy enough to wear to the pub or out to tea, the Altitude tee does the job exactly as described. The skull cap is brilliant. Small, warm, thin - definitely an essential piece if kit for Autumn/Winter in Adelaide.

Short version is - more than happy - hoping for a good long life and will look to buy more. The Ultra fabric smoother - the Altitude "feels" tougher. Might go for Altitude when looking for warmth and robustness - Ultra when looking for style & comfort.

A solid 4 1/2 out of 5 stars and I am told I am not easy to please!!!!!

Cheers

I am an IOMerino convert

This is my third Merino top (I also have the leggings and neck warmer) and I LOVE THEM ALL. The feel and fit is great and spending 5 weeks in Norway and Sweden I wore IOMerino daily - its comfortable, kept me warm as I used it as layering. We did park runs and in the freezing cold and most times all I needed was the crew top (ditching a jacket before I ran and warming up in a few Ks). I now have no need to look elsewhere for my merino gear - this is THE BEST merino stuff I have worn - and I have been through alot of brands!

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.
