If you’re looking for comfort and performance with a little bit of fun thrown in for good measure, the Altitude ‘Mongrel’ is for you. It may not have the most flattering name, but the superfine Merino fabric certainly performs, and feels, as good as ever.

Step 3: Add to Cart*

Qty:

Sure you could buy one of our best-selling Altitude base layers in a regular colour like black or grey, but if you’re looking to add a little extra fun to your next adventure, this one’s for you. But don’t let the name fool you, this is one seriously good thermal base layer. 

The Mongrel is mostly made from our flagship Enigma MicroMerino® - 96% superfine Australian Merino and 4% Elastane for an easy four way stretch. There’s also a few different premium Merino fabric panels thrown in, but rest assured they’re all still super soft and comfortable. The first Mongrel sold out in record time, and we generally make them in fairly limited quantities, so if you’re keen, it’s best to get in sooner rather than later.

Behind its colourful exterior, the Mongrel delivers the soft-touch comfort you’ve come to expect from our Altitude range, as well as natural breathability, temperature regulation, moisture wicking and odour-resistance. Because looks aren’t everything, right? 

Key Features:

  • Made with a mix of superfine Merino fabrics offering high performance and an incredibly soft next to skin feel.
  • Drop back hem designed for tucking into your outer layer, meaning that your skin is never exposed when bending or moving.
  • Thumb loops that stop your sleeves riding and bunching under your arms when layering.
  • Tag free, flat lock stitching and raglan sleeves eliminating chafing, maximizing comfort and next to skin contact.
  • Ultra Trail Australia mandatory gear approved

What you need to know:

  • Layering: Base Layer
  • Weight: Lightweight (170 gsm)
  • Fit: Contact
  • Length: Drop back hem – extra length at the back
  • Main Fabric: Enigma - 96% Merino & 4% Elastane. Fabric panels: 100% Merino, 96% Merino & 4% Elastane

     

Natural MicroMerino® benefits:

  • Naturally breathable and temperature regulating. Helps keep you warm when it’s cool and cool when it’s warm.
  • Moisture Wicking. Stays warm even when it’s wet and naturally wicks moisture away from the skin for extra comfort.
  • Odor-Resistant. Natural antimicrobial properties to prevent odor – especially good for travelling and extended adventures.
  • Made with only the softest, finest Australian Merino wool. Designed and knitted in Australia for adventure.
  • An ethically and sustainably produced natural fibre. Good for the people who make it. Good for the planet.

Enigma:


The ioMerino 'Enigma' is our flagship fabric. Featured in our Altitude range. 

'Enigma' is a lightweight 170gsm single jersey MicroMerino®, knitted using 18.5 micron 96% full-fleece Australian Merino wool knitted and 4% elastin.

The combination of merino wool and 4% elastin in the 'Enigma' fabric ensure perfect body contact, eliminates excessive bulk, and a 4-way stretch allowing your limbs to move freely as the fabric does not inhibit your range of motion.

Benefits of the ioMerino 'Enigma' fabric:

  • Moisture management wicking - moving moisture away from the body keeping the body dry and cool
  • Antimicrobial - Moisture absorption properties reduce the tendencies for a build-up of odour.
  • Luxuriously soft next to skin
  • Breathable and temperature regulating
  • Ultra-comfortable warmth
  • Maximum warmth, minimal weight
  • Quick drying

All ioMerino fabrics are fully machine-washable.

    Really love this top

    Review by RJF on 9/29/16
    This is the perfect top for winter runs when you're freezing at the beginning, but get warm quite quickly. It's comfy and looks lovely too. I want to wear it all the time, I wish I could afford a few more.

    So comfy!

    Review by Belle on 8/22/16
    A fantastic long-sleeved thermal top, and I love how it has a little stretch too! Good length in body and arms, I found I didn't need to adjust it/ pull it up or down at all. So comfy and soft!

    Review by Freya on 8/11/16
    May I say how awesome your mongrel top is? I wore it last week on a cold morning and it was unbelievably amazing. I knew it would be but with the awesomerific colours, it made me train even better

    Review by Ollie on 8/5/16
    Got mine yesterday, went to try it on for size,felt so good, I've been wearing it ever since. Looks great, hugs my curves, nice and long over the bum so it won't pull out of my jeans. Even makes my boobs look perky. Winning! Thanks IOMerino. :-D

    I live in these

    Review by Meagan on 7/26/16
    This is a great winter top. Running, riding or just staying warm. Love the long body length so there are no cold belly and the long arms to go over my hands. And the funky design. Thank you IO Merino!

    I love this Mongrel top!

    Review by Deanna on 7/5/15
    A couple of friends and I each bought this top as we were doing a 2 day mountain run together. The Mongrel top was perfect, it kept us warm in chilly mountain weather but was not too hot, even when our hydration packs were sweaty on our backs from running all day. We looked awesome and we got a lot of great comments about our 'team' top.
    I was deciding whether to choose size M or L and went with L, which was the right decision. It fits perfectly, the M would have been snug around my mummy tummy.
    I'm kind of hoping IO Merino bring out another one (with more of the light blue colour on the sleeves and purple down the centre), as it would give me a good reason to buy another one ;)
