Made from our revolutionary, new, Merino Wool compression fabric, the Arm Warmers are ideal for changing weather conditions and trans-seasonal weather. 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.

Unlike regular arm sleeve, this fabric has a high merino content so are fully breathable, lightweight, and deliver both UV protection from the sun and warmth without bulk, and help stop you overheating. Pair with a t-shirt to add some additional warmth and versatility to your favourite short sleeve ioMerino.

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.

Model is 6'2" and wears size L/XL. 

Choose size based on what base layer top size you wear.

Exactly what I wanted!

Can’t believe I’ve waited so long to purchase quality arm warmers. The catalyst is NYC Marathon 2019 where it will be cold to start off and they’re perfect. Super easy to remove mid-run and a great fit. I was worried that they’d fall down but no way. I took a size XS/S and I’m really pleased with the product.

Versatile Layering on the trail

Having recently completed a 17 day thru hike in the NT, these arm warmers were invaluable. Very cold morning starts and they were on, then by mid morning they came off easily without having to take off my back pack. They were also weight saving as I found they added a long sleeve layer to my T-shirt. Brilliant!!

Thank you so much for your kind words, Ann-Marie. We really appreciate you taking the time out to share your experience with us - we agree, the arm warmers are brilliant!

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.
