They maximise heat retention and offer additional coverage in low temperatures, but are easily removed or rolled down if it warms up or if you're wearing a pack.

Tag-free labels and flatlock stitching eliminate chafe and maximize comfort. Silicone grippers at the inside top hem to hold them securely in place around your arm and the reflective trims add visibility in low light conditions.

Female model wear size XS/S. Model is size 6-8, height 170cm, chest 81cm, waist 63.5cm, hips 89cm

Great for cycling

Bought arm warmers to use with ioMerino cycling jersey. Was told to order same size as jersey, and though I initially thought too tight, find they work well on the ride.

io Merino cycling jersey and arm warmers are perfect combination for cycling in cooler weather.

Pain relief

Had an injury on my right harm and now suffer of really painful golfer elbow. Warmth help and those are perfect when I exercise and don’t want to put a long sleeves too

Used as arm warmers for cycling

good warmth and breathe ability for winter. Probably too warm for all season. Would love something lighter in a summer or uv sleeve!

toasty arms

I was unsure about arm warmers but a few runners said they are great and they were right, Canberra weather means you sometimes need more than a t-shirt but not quite long sleeves, the IOMERINO arm warmers are perfect - kept my arms warm running and on my bike - amazing gear.

Best arm warmers.

I use these for cycling. They are hands down the best fitting and performing arm warmers I have ever used.
The sizing chart was correct. Customer service was also excellent.

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.
