Altitude Range - 'Contact Fit'

The Altitude range is designed to be a tight, but comfortable, fit. If you size up it will give you a little extra room, but it will still hug your body as that’s what this range is designed to do. If you want a looser fit consider the Ultra or Universal range.

Universal and Ultra Range - 'Regular Fit'

These garments are designed true to size, but going up a size in the Ultra will give it a slightly looser fit, whilst remaining sporty. The Universal is already designed as a more casual fit.

DETAILS

Whether you're on the trails or the slopes, the rivers or the mountains, you're going to want to add a pair of the Altitude Base Layer Thermal Tights to your kit. These tights are incredibly soft and will help keep you warm when it's cold and cool when it's warm for year-round comfort, no matter what the weather. So when you’re out in the elements being active, your legs will stay toasty warm without overheating and won't get stinky and sweaty like synthetics.

The Altitude Tights are the same thickness as the Altitude tops. They are a classic thermal leggings style and great for warmer to cool temperatures as base layer pants.

Tag-free labels, flatlock stitching and a flexible, ultra-soft ioMerino elasticated waistband help eliminate chafe and maximize comfort. The mid-rise style works perfectly with the Altitude Base Layer tops to ensure no exposed cold spots when you're on the go.

Ultra Trail Australia mandatory gear approved thermals.

SIZE & FIT

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

Warm and comfortable base layer

These fit nicely and are perfect as a base layer. They’re a little bit see-through and pretty thin, so I don’t plan on wearing them on their own, but despite how lightweight they seem, they have kept me warm under a second layer.

Mine have names!

These little babies are utterly essential for this old chook to survive winter in SA`. I’m 83 and to heck with all the fit athletic types you normally sell to. These make the difference between life and existence.
I have multiple pairs and an equal number of tops.

Altitude tights 5 star

Lovely to wear, comfy and warm. Good fit. Thank you.

Best Base layers ever.

I have always had problems with temperatures that change from morning to evening. These are excellent for keeping me comfortable all day. Warmth and coolness when needed. I have purchased many tops and two bottoms. Just this season so i have to wait til next season to add more.to my wardrobe. Also great to wear as base layer in winter when sleeping.

Thanks Sharilyn!

Some are made in China!

They are nice, smooth, warm, well fit, comfortable, etc. like many things I like from Iomerino. The shocking thing is that I recently bough a black pair, and they were made in China! I don’t think the quality is suffering but I thought all Iomerino items were made in Fiji. China dominates the world in just about everything. I would prefer not buying things made in China if I can help it. Please put the information on the web to help one make decisions in buying the products.

The good news is we moved away from manufacturing in China a while back now for various reasons, and now predominantly manufacture out of Fiji where we have much better guarantees around ethical production. Rest assured your garment will still be made from our premium Australian wool, knitted into fabric here in Australia and made to our usual exacting standards, it just must have been manufactured before the shift.

Loose

Tights were very loose on me and I'm always an xs. Customer service is top notch though.

Thanks for taking the time to give us a review Sangavi! I'm sorry that the XS were too big. You might like to try our Compression Leggings which are available here: https://iomerino.com/products/mens-merino-compression-leggings?_pos=2&_sid=391d6e783&_ss=r&variant=20317881270330

Awesome

One of my specific reasons for buying the polo, apart from wearing it casually, I wear it under my yellow protective clothing as a volunteer firefighter. It is extremely comfortable in very hot conditions as it does not stick to your skin when sweating heavily and with the wicking ability helps with managing my body heat. Being wool it also gives that second level of protection against burn injuries.

Hiking Socks

Amazing!

I have stopped wearing leggings under my skirts for awhile now because of all the synthetic fibers and I decided to get these after a very long search to find the best. After about 1.5 months of searching and reading reviews I decided to get these. I followed the size guide and I found a perfect fit, I never want to take them off. Now I wear long, mostly ankle length skirts and I run in them so I sweat and I sweat a lot but these are amazing. I also have very stretched out skin from having children and these really hold things tight so my skin doesn't hurt when I run or itch. So pleased! I'm super excited to get a second pair but I need to save a bit for them. They also keep their shape after a couple days. I'm so thankful!

Great trackies

These track pants are a delight to wear. They are light comfortable and easy to wear during any activity. They also wash well. Also smart enough to wear while just out and about.

Stride Tracksuit Pants

Perfect for travel

These yoga pants were perfect for my recent trip to the UK. Comfortable all the way during the long flight and perfect for the cold weather there on arrival. I wore them the whole time I was away and they didn’t crease, lose shape or go baggy in the knees! Am about to buy another pair…

Universal Tee

the best trunks on the market

being an avid supporter of the merino industry and io merino product i purchased 3 pairs of the mens trunks about 12 months ago- it was not long before i dreaded wearing the cotton brands i was wearing prior to that. I then purchased enough IO mens trunks to ensure i had 100% comfort 100% of the time.

Ultra Trunks

Fabulous hoodie and amazing service!

I’ve been after a good hoodie for a while and had my eye on this. I bit the bullet on Monday, called up, got great service over the phone and when I got home from work today it had arrived! The hoodie itself is feels so soft, fits great and the quality is amazing. Now considering buying a different color! Thanks IO!

Summit Zip Hoodie

New Running Long Sleeve

Only used a couple of times but it’s great. Comfortable fit keeps me warmer than a t shirt and the thumb holes help keep fingers warmer on frigid hills mornings. Time will tell for durability. Love the colour (mint I think)
