We know how much you love our best-selling Zodiac Boxers, but some of you wanted something a little sportier to fit better underneath another performance layer like our leggings. You asked. We listened. And here they are. Sleeker. Regular fit. Breathable. Temperature regulating. And odor resistant. Do we hear an Amen?  

With a leaner, firmer, more active fit, there's less fabric in the legs and crotch, and they’re also a little shorter than the original Zodiac Boxers. Wear them every day. While you’re travelling. Camping. Up a mountain. While you’re skiing. Or to a business meeting if you like. It’s up to you. One thing’s for sure, you’re going to love them. A lot. Say goodbye to ordinary undies, and hello to the Altitude Active Boxers.

Made with the flagship MicroMerino® Enigma fabric - 96% superfine Australian Merino and 4% Elastane - these boxers offer an easy four way stretch for extra comfort and freedom of movement, plus flat lock seams, a soft elasticated waist band and fully functional fly-front so they’re as functional as they are comfortable.   

Key Features: 

  • Made with the flagship MicroMerino® ‘Enigma’ fabric, 96% superfine Australian Merino and 4% Elastane for an easy four way stretch 
  • Superior 18.5 micron soft and lightweight MicroMerino® provides a luxurious next to skin feel
  • Soft and flexible elasticated waist band
  • Tag free, flat lock seams to reduce bulk and chafe
  • Fully functioning self-fabric fly
  • Incredibly lightweight and soft touch

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% elastane.

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.

    Great item but not in summer

    Review by Andy on 8/9/17
    Very comfortable and greater most of the year, but in summer the legs are too long and this underwear becomes very warm to wear. Could iO make some where the leg is shorter? In this way these are an improvement over the Zodiacs for a Sydney summer.

    Simply the best for hiking and everyday

    Review by Robert on 5/27/17
    No chaffing, fast drying. They are so comfortable you are not even aware of them. I wish I could afford more pairs, I would wear them all the time.

    Boys were very happy

    Review by Action Man on 11/22/16
    I found these boxers underneath hiking shorts are the perfect approach for long distance hiking- 2 pairs would sort me out for any trip shorter than the Pacific Crest trail...
