Icebreaker Tracer Pants Review

Icebreaker has become the standard bearer for merino wool performance apparel, with a wide inventory of products ideal for multi-sport use.  Merino wool provides natural breatheability, effective insulation even in wet conditions, and outstanding odor resistance – and Icebreaker’s fabric construction produces garment that feel very comfortable against the skin.

This spring Icebreaker introduced their GT Run apparel, a premium line designed specifically for runners, with loose-fitting shirts and shorts that deviated from the company’s original form-fitting garment options.  Earlier this fall they extended the GT line to include the Tracer pant, a sort-of form-fitting, sort-of loose pant that is equally suitable for hard workouts or lounging around the house after a long morning run.

The Tracer’s material construction consists of 97% merino wool and 3% Lycra to provide a small amount of stretchiness and full range of motion.  Thickness is classified as GT260 – with Icebreaker, higher numbers are thicker – making the Tracer great for cool weather, but not severe cold; my comfort range with these is anywhere from 50 degrees to just below freezing.  The material is thin enough to wear as a base layer, but the looser-than-normal fit (especially around the ankles) makes the Tracer more cumbersome than a pair of traditional base layer tights.

Elastic and drawstring waist; dual zippered pockets

Because they’re quick-drying, very comfortable, and naturally odor resistant, it’s easy to wear the Tracer for a run and keep them on for the rest of the day.  I give them equal duty as workout pants and “first thing I put on in the morning” sweatpants when rolling out of bed on my non-workout days.

Good Tracer

  • Comfortable fabric
  • Great breatheability
  • Excellent odor resistance
  • Dual-purpose fit for active or casual use

Bad Tracer

  • Dual zippered pockets are slightly bulky for high-intensity running
  • Not preferred for layering compared to tights

Bottom Line: Icebreaker Tracer Pants

With all-day comfort and good versatility for cool-to-cold use, Icebreaker’s Tracer pants are a great multi-purpose item for your autumn athletic wardrobe.

  1. Very excited to find this review here. I’ve been looking to replace a pair of Patagonia R3 wool bottoms for about two years now. Until seeing these, I couldn’t find wool bottoms with zippered front pockets. I’ll have to grab a pair of these- thanks

  2. Thanks for the review Donald!
    How do you find the pants fit length-wise? At 6’5″ I’m a little concerned they won’t be long enough for a small-waisted, long-legged guy like me.

    • @Philip: Sorry for the delayed reply … but yeah, you might have a problem depending on your waist size. I’m 6’2″ with a 32 waist and 34 inseam, and I wear size medium (based on waist size). The length is just about perfect, or maybe a tad bit short.
