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.

    perfect

    Review by Jenny on 2/27/15
    I own several merino tanks from different companies, and this is my favorite. Soft, great stretch, sexy fit. I've had mine over a year and wear it weekly or more, with no pilling, holes, or loss of shape. Note for I/O crew: description/photo should mention/show that it's a racer-back tank and fits perfectly over the I/O "crop top" (which is actually a a great sports bra).
