Do Your Research:
Insulation

The whole premise behind insulation is heat retention, but choosing the proper insulation is based on your activity level. Down garments are designed to keep in as much heat as possible, making them ideal for stationary warmth. If you are consistently on the move and generating body heat, a more breathable synthetic insulation may be a better option as it will help prevent overheating and the build-up of sweat.

3 KEY ELEMENTS

Temperature:

The colder the temps the more insulation you will need. Down will add more warmth to your layering system, but synthetics excel in active cold weather situations. Combine vests with jackets and add insulated pants for extra warmth.

Activity Level:

Active mobile hunts call for more breathable insulation to combat overheating, where stationery situations need a less breathable fabric to trap your body heat. This is determined by your hunt style, are you constantly sitting and glassing, or staying mobile bouncing from canyon to canyon.

Weight | Durability:

One of the main benefits of a good insulation piece is its warmth:weight ratio. They are designed to be as light as possible, so pay attention to fabric weight if durability is important.

Kenai Ultra

An incredibly lightweight yet durable synthetic fill jacket that breathes far better than other insulation layers, keeping you comfortable during strenuous activity. Ideal as a warm mid-layer, or as an outer layer piece for high-output cold weather mountain hunting applications. 3DeFX+® synthetic insulation is the first of its kind to incorporate continuous fiber technology. The long spiral strands of fill are loftier and warmer and don’t require fabric coating to keep the insulation from migrating through the fabric. The 30D Stunner Stretch nylon face fabric is strong, light, and dead quiet. Uncoated fabric and body mapped insulation allows us to make a jacket that breathes at an exponentially higher rate, keeping the user dryer, warmer, and more comfortable during long climbs and extremely active use.

  1. Weight: 14.5 oz
  2. Body mapped with 90g in the front and 60g in the sides & hood
  3. Coated with Toray DWR for water resistance
  4. Highly Breathable to prevent overheating
  5. Ideal for high-output cold weather hunting applications

Super Down Ultra

Designed for the outdoorsman looking for an incredibly lightweight yet warm insulation piece. This jacket should be in your pack on every hunt until the weather turns and more insulation is needed. With a mid-layer fit, the ULTRA has room for base and additional mid-layers, but fits snug enough so there is no bunching if worn under another jacket. Constructed with a 12D nylon ripstop that stretches with your body minimizing restriction. 2.3oz of 850+ fill goose down treated with a DWR on each individual cluster makes the down impervious to moisture. A specialized finishing process gave us the ability to use less down proof coating to create a lighter and more durable fabric. This new process in addition to the down proof coating makes the fabric completely windproof. The ideal piece for any early - mid-season hunt.

  1. Weight: 7.9 oz
  2. 2.3 oz Premium 850+FP Quixdown
  3. Down & Fabric treated with Toray DWR
  4. Windproof face fabric

Built for extremely cold situations. Packed with 5 oz of Toray’s water resistant Quixdown, this is the warmest insulation piece we have come out with to-date. Sized like our Rain Gear, this jacket is cut to fit over the top of all your layers except your hardshell. Multiple features allow you to tailor the fit to your body and trap or exhaust body heat. Constructed with a durable 30 denier stunner stretch face fabric that is coated to keep the down from migrating through, which in turn also makes this fabric highly wind resistant. Look to the Super Down Pro for cold weather stationary hunts when you are consistently glassing from a windy ridge or sitting in a blind.

When purchasing an insulation piece take these three key elements into consideration to help make an educated decision. Figure out where in your layering system you want your insulation to fall, think about your activity level, and know your expected temperature ranges when figuring out what level of insulation is needed.

The Feather Scientists

International Down and Feather Laboratory, or IDFL, is one of the world's foremost authorities on testing down and other filled textile insulation. The outdoor industry throws around terms like loft, fill power, down percentage, and DWR, but what do those terms tell us? This film reveals IDFL's procedures, showing what the numbers on the spec sheet really mean, and gives a never-before-seen look into KUIU's process for certifying the Toray Quixdown found in our Super Down products.
