Are you ready to hike?

Hiking the local trails

Whether you’re going for a short hike, or a multi-day adventure, you’ll stay comfortable for longer through all sorts of conditions when you choose the right gear for the job. With natural breathability, temperature regulation, moisture wicking and odour resistance, you’ll enjoy your time on the trails even more when you go with io. 


You're probably thinking something along the lines of 'why would I buy Merino underwear when I can just wear my regular cotton ones?'. Well, you could, but surely you'd want to keep your valuables just as warm and comfortable as the rest of your body? It's amazing how many people put a whole lot of thought and effort into what layers are going to perform best, then wear their regular undies. There's a good reason Search and Rescue teams across the world refer to cotton as 'Killer Cotton', so be sure to check out our boxers, briefs & trunks for men and hipster briefs, bikini briefs & thongs for women before you hit the trails next.

OK, so these bad boys are going to keep your feet warm and comfortable out on the trails, but they're so much more than that! In fact, these are more like 'don't leave the house without them' kind of Socks and will go from the trails to everyday seamlessly. With a whopping 80% superfine Merino Wool, they're one of the most Merino-iest Socks going around and offer a whole lot of warmth, comfort and natural performance such as odour-resistance (yes please!), moisture wicking, temperature regulation and more. But don't be fooled, these are not thick, sweaty and uncomfortable hiking socks, they're actually incredibly lightweight and with ventilated panels in the areas you need it the most, your feet will stay fresh at all times. We've also added extra padding in certain 'comfort zones'.

Neck Warmer 

Let’s be honest here, we basically stuffed up when we named this the “Neck Warmer” - we probably should just call it a ‘Multi Purpose Gotta Have Head Thing’. Yes, it can keep your neck warm, but it can also be worn as a headband, bandana, beanie, face mask… the uses are endless. You’d basically be mad to not have one of these handy when you’re out and about. Unlike other “Head Things”, the unique MicroMerino® fabric will prevent any condensation build up from freezing and it’ll stay warm even when it’s wet. Check the Altitude Neck Tubes out here.

For many hikers and campers, cold hands can be a real problem 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.

T-Shirts and Tops

If you’re looking for a genuine base layer that fits close to your body and can be worn underneath your other layers, it’s the Altitude you’re looking for. Nice snug fit, extra length for tuck at the back, super soft and comfortable. There’s a zip version for extra warmth and flexibility. 

Don’t need a tight fit, but want something a little bit streamlined? Check out the Ultra range. Still super soft and comfy, but doesn’t have the extra tightness of the Altitude, has a bit more room, and a bit of nylon added for extra durability. The Ultra range also features a zip version.

If you’d rather go for a classic, casual fit, check out our Universal range. Same fabric as the Ultra, but a looser fit. No Zip version here, but it’s probably the classic hiker’s fit and if you’re looking for something that’s a little more forgiving, this is the one for you.

These here are from our base layer Altitude range:

These are from our sportier fit Ultra range:

And our classic, casual fit Universal range:

Summit Hoodie 

And if you're heading someplace where you know you're going to need extra warmth, then you might choose the Summit Hoodie (men's and women's) instead. Made with the same 100% Merino fleece fabric, this Hoodie offers the same level of warmth and comfort, just with the sleeves!

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!).

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.
