PRIMALOFT GOLD - HUNTING INSULATION GARMENTS

Not all hunting insulation garments are created equal. Insulations are a highly debated topic among backcountry enthusiasts and for good reason. I am not going to go into the down vs. synthetic debate; we will break that down in a separate post. The quality of synthetic insulations vary widely in quality, and unless tested, lesser brands can prove to be vastly inferior. In today’s technological age, independent testing can show reliable data supporting the warmth to weight ratio in a given synthetic insulation. This ratio is also known as the clo rating or the fabrics relative measure to keep the wearer warm. The clo is the standard unit of measure to test insulation.

Primaloft Gold 0.92 dry / .90 wet, clo/oz
Primaloft Sport 0.79 dry /.72 wet, clo/oz
Synergy .73 dry / .61 wet, clo/oz
ECO .68 dry/ .60 wet, clo/oz
800 fill down has a clo/oz of about 1.1.

To break this down, Primaloft Gold is the best available synthetic insulation available in its class. Is down warmer, yes it is, but that also depends on the down weight and its quality. Without lab testing, it is hard to say exactly what weight Primaloft Gold would equal in down, but it has been presumed to be in the 450-550 fill range regarding warmth.

  1. Warmest insulation available
  2. Very light weight
  3. More packable than synthetic
  4. Worthless when wet

The garment construction also plays a critical roll in the overall clo value. If you take into account the stitching, fit and design, the clo rating, as well as heat retention, can vary greatly. As an example, a synthetic fill garment that compresses the insulation has an unsealed neck and a lot of seams will release heat much faster than a properly constructed garment. Another aspect to take into account is the garment shell/liner. If the shell is windproof, heat retention will be higher. However, the garment will be less breathable. Your activity level should determine the type of garment that you choose.

Primaloft Gold shines in warmth to weight as well. It would take much more ECO to hit the same clo rating as GOLD which means that the wearer is getting more warmth out of a lighter garment.

Primaloft Gold for Insulated hunt wear:

Most of you are familiar with Primaloft. As far as outdoor synthetics go, they have been the leader of the pack in quality and innovation for 20+ years. Primaloft manufactures many insulations that differ in composition and weight that are designed to perform in multiple climates and scenarios. We opted to run with Primaloft Gold for a few reasons. First off, Primaloft Gold is their highest performing synthetic. It has a great weight to warmth ratio and maintains a CLO rating of .92. The second reason we loved the idea of The Primaloft Gold line is that it is available as a USA manufactured product. Primaloft still utilizes a manufacturing facility in WACO, TX and that held value to us. So the decision was easy.
