Measure Yourself:

Use the chart below to determine your size. If you're between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit. If your measurements for chest and waist correspond to two different sizes, order the size indicated by your chest measurement for tops and your hip measurement for pants.

How to measure yourself:

  • Arm Length: Measure from the back of your neck across the top of your shoulders to your elbow, and down to your waist.
  • Bust: Measure under your arms around the fullest part of your bust.
  • Waist: Place the measuring tape at your natural waist, the narrowest part on your torso.
  • Hips: Measure around the fullest part of your hips.

Fit Guide:

Icebreaker have three different fits - slim, regular, and relaxed - ensure that when worn together, layers move and breathe like a single garment.

  • Slim Fit - A snug, close to body fit for low bulk layering.
  • Regular Fit - Neither snug nor loose - garments that are worn solo or over other layers.
  • Relaxed Fit - Loose fitting lightweight layers.

The Australian winter is breathtaking, yet bitter - make sure you're prepared.

A mid-weight base layer should be an essential part of your winter setup and if you're active throughout the winter, this is the base layer for you. The Winter Zone is a highly technical, half-zip top with optimised fabric zones for active performance in cold conditions. The body component features a 260gm merino wool fabric with a touch of Lycra for stretch. A plunging front zip helps unload any additional heat and in the underarm panels a lightweight, 180gm eyelet merino mesh is utilised to actively control temperature during high-output pursuits. In addition, any areas that are prone to higher-wear have a 230gm merino and polyester waffle jersey for added abrasion resistance.

Icebreaker BodyfitZONE base layers employ the most advanced temperature-regulating natural technology. The soft and odour-resistant merino is used in different fabric forms to trap heat where it's needed and releases it when working at high intensities.

  • The flat-lock seams throughout the garment eliminate chafing during fast-paced days.
  • A deep half-zip assists with ventilation.
  • Ideal for snow sports, winter running & fitness.
