If you’re looking for natural performance, easy layering and a whole lot of comfort, then look no further as the Altitude Zip is one seriously good thermal layer. Whether you’re wearing it as a base/first layer, on its own, 3/4 zip up or down, it’s perfect for anyone who’s on the go, especially if you’re expecting to hit a range of temperatures while you’re at it. The high collar, when zipped up, also offers an extra level of warmth beyond the Crew Neck version of this top.   

Made with our flagship Enigma MicroMerino® fabric – 96% superfine Australian Merino and 4% Elastane, the Altitude Zip features all of the performance you know and love in our MicroMerino® garments, plus an easy four way stretch for freedom of movement when you’re on the go. Oh, and did we mention the incredibly soft next to skin feel? 

With flat lock seams, heat transferred tags and raglan sleeves to help prevent chafing, plus thumb loops and a drop back hem for easy layering, the Altitude Zip is the perfect combination of performance, warmth and comfort.

 Designed to be worn as a snug ‘contact fit’ layer, we’d recommend going up a size if you’re looking for a more casual fit.

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.
