Klim Defender Pants

Utilizing the same micro-grid polyester blend knit materials as the Defender ¼ Zip Shirt, the Defender Pant fills the gap between KLIM’s Aggressor and Inferno pant with an athletic, comfortable fit and just the right level of warmth. A Seamless in-seam construction and ultra-comfortable crotch gusset means all-day riding comfort courtesy the newest medium-weight layering pant from KLIM.


  • Medium-weight base-layer
  • Highly wicking, quick drying micro grid polyester blend knit main body material
  • Ultra-comfortable 95/5 poly/Spandex blend
  • Athletic contouring fit
  • 4-way stretch comfort
  • Anti-microbial
  • Anti-piling
  • Flatlock stitching and tagless design for maximum comfort


We highly recommend finding a cloth tape measure and taking the time to take these measurements.  Klim sizes will not necessarily correlate with fitment in other brands.

Good Gear As is customary from Klim, this is good gear. I put these on under a BMW GS Dry Suit and covered 444 miles over a twelve and a half hour day visiting three state parks. Temps were from 30 to 46 with a North wind. They were great on the road and didn't get too warm for comfort when I stopped for lunch and dinner in some pretty warm restaurants. I like them.

My Warmest Base Layer These are reserved for the coldest days. Short of that I use KLIM Aggressors. With layering and pairing being the true paths to comfort, warmth, and proper ventilation, this layer provides the greatest degree of on-skin cold weather comfort . Their fit and construction are excellent. If needed, they air dry quickly overnight. I'll never be without these. KLIM gear has significantly changed the way I ride for the better. Their design, comfort, safety and sensibility match my needs ideally. April 14, 2014
Great addition to an already comfortable and functional Klim Latitude 2 pc riding suit. Just the right amount of insulation for moderately cold days. The fit of the XL is near perfect for my 6'3", 36"waist and 35"inseam. Designed to be worn in cooler temps,the material also does a great job of wicking away any excess heat and persperation. Does not bunch up and the seams are done in a way that feels comfortable all day. The Klim Latitude pants are not designed to be worn over street clothes and the Defender pants fit perfect under them. Great product! January 14, 2013
