Whether you’re out on the road or the trails, out early or late, day or night, or even fast or slow, ioMerino is absolutely epic for running and helps you stay ready for anything out on your adventures. We’re mostly blessed with beautiful sunny weather here in Australia, but get our fair share of cold mornings/nights and days, especially during winter. Rest assured, we certainly don’t let that stop us from getting out there and doing all of the things we love – after all, there’s no such thing as bad weather, only inappropriate clothing!

We know we’re not the biggest Merino brand in the world, but with six generations of wool know-how, we’re no rookies when it comes to making some of the best Merino gear on the planet. And as official sponsors with approved and compliant mandatory gear in some of Australia’s biggest running events, including Ultra Trail Australia, we’re not just all talk – even the experts happen to agree with us on this one!

So either you’ve accidentally taken a wrong turn and ended up here, or you’re interested in hearing more about the Merino thermal layers we recommend for running, in which case, let’s just cut to the chase.

(Btw, we haven’t just pulled these recommendations out of thin air, but rather taken advice from our Trail Running Team – those who are out there running in our gear everywhere from Indonesia to New Zealand and in some of the world’s most legendary events including the Tarawera Ultra Marathon, Ultra Trail Australia, Big Sur Marathon and many more, so their advice is probably as good as any!).

Let’s start with the basics.

If you want Merino Socks, we’ve got em’. They’re super soft, feel ridiculously good straight out of the pack, and have 80% Merino Wool content which makes them some of the Merino-iest socks on the planet. While these socks are great for a range of activities (hence why we called them the ‘Multi Sport Socks’!), they’re particularly good for running. With anti-chafe and anti-blister technology, ankle cuffs to prevent sock ‘slippage’, padded ‘comfort zones’ and ventilated panels for breathability and thermo regulation, these are certainly no ordinary socks!

We know plenty of you will be wearing running shorts, but if you need something underneath those, these Merino thermal undies (men’s & women’s) are the go. Soft, lightweight and with all the benefits of a Merino layer. To keep your ‘valuables’ safe, warm and comfortable.

This lightweight Merino skull cap is the perfect running partner if you’re looking for additional head warmth. It delivers an unrivaled level of softness and warmth while remaining completely breathable and temperature regulating. And thanks to the streamlined design, there’s no uncomfortable bulk or gathering!

This ‘Head Thing’, as the boss likes to call it, can be worn as a headband, bandanna, beanie, facemask, ear muff… the uses are endless. OK, maybe not endless exactly, but there are certainly a lot of uses and you’d basically be mad to not have one of these handy when you’re out and about. And unlike other ‘Head Things’, our Merino fabric will prevent any condensation build up from freezing and it’ll stay warm even when wet.

For many runners, cold hands can be a real problem when running in cold weather. Your arms and legs usually warm up nicely enough, but your hands don’t have the same level of circulation and can stay cold, so a good pair of gloves is essential. Ours are lightweight, natural, breathable, soft, warm and comfortable. And you can even use your touchscreen devices without taking them off, thanks to the touchscreen-friendly pads on the thumb and forefinger.

It’s all about the base.

If you’re serious about staying warm and comfortable, you need one (or two!) of these in your wardrobe. Breathable, lightweight, moisture wicking, odour-resistant, ridiculously comfortable… the Altitude Tops aren’t one of our best sellers by accident. These are as soft and comfortable as they come. If you like a regular neck, go Crew. For extra warmth, go Zip. Pack them in your kit (a men’s XL fits into a sandwich bag!) and you’ll not only have a few mandatory items sorted, you’ll be ready for anything during your run and on future adventures as well.

For those of you who live in milder places, or aren’t really fans of sleeves, no problems, we also offer an awesome range of Merino Tees! They’re incredibly lightweight and packed with the same performance as the long sleeves such as breathability, temperature regulation, odour-resistance and more. Wear them on their own in milder conditions, or layer under, or over, your long sleeve when the weather really hits hard. If you’re after a contact fit, go Altitude and if you’re after more of a regular fit (particularly handy for those of us who aren’t rocking six packs!) go Universal. And if Tanks are more your kind of thing, check ours out here (men’s & women’s).

Check out our full range of men’s and women’s Merino Tees here. 

NOTE: This range was originally developed for high Altitudes and extreme weather, so it features a contact/base layer fit that can be worn under other layers or on its own, and extra length back drop hems so you don’t get any cold patches by coming untucked. They’re still awesome for running, of course, but for our new running-specific range with a more regular sporty fit, check out our Ultra Range below.

Ultra Range

Our new Ultra Range is ultra-natural, ultra-breathable, ultra-comfortable and, of course, ultra warm for such a lightweight garment. The tops and tees are packed with high performance features and they’re just perfect for running in cold weather. Wear it on its own if it’s just a bit chilly, or layer up when the temperature really drops.

The long sleeve features thumbholes to help keep your hands warm and to make your sleeves stay put. The Zip gives you the flexibility to un-zip when you need to catch some extra air. Super useful if you warm up while you’re on the go. It also features a higher collar for extra warmth around your neck!

Keep your legs toasty warm.

Sure, you could buy cheaper, synthetic leggings, but these are way better. See everything we said about the Altitude Tops? Well these are made of the same stuff, so all of that applies here as well. The Altitude Tights are super lightweight (in fact, one of our most lightweight garments!) and breathable, yet incredibly warm. Admittedly, you might want to wear a pair of ‘courtesy shorts’ over the top as these are great thermal layers, but not completely opaque.

If you’re looking for even more warmth, then the Chaser Leggings are for you. Make no mistake, at almost double the thickness of the Altitude Tights, these aren’t base layer tights that require an extra layer over the top, these are wear them as they are Leggings. Still not sure if a pair of Merino Leggings are for you?

Any questions?

As always, our team and Outsiders are pretty helpful when it comes to answering questions, so if you have any that aren’t too difficult, send us an email anytime and we’ll get straight back to you. (Unless we’re out hitting the trails ourselves in which case you may need to be a teeny bit more patient!).
