Big Game: Open Terrain

I’ve refined my system for about 15 years but write this with only one caveat — don’t simply take my word for it. Yes, these are my personal choices, but the ideal setup for you may vary based on your body type, hunt conditions and preferences...

Features & Benefits

3/4 Side Zips

3/4 side zips allow for venting and make for an easy on/off as conditions change.

Secure Pockets

Zippered hip pockets and quiet snap cargo pockets keep you organized.

Durable Water Repellent Finish

The DWR finish resists light precipitation and prevents the face fabric from wetting out.

Reinforced Seat

The seat is reinforced for extra protection when riding and hunkering down in rugged country.


The Blizzard Bib Pant is insulated throughout with the world’s first water-repellent hybrid insulation of 60% 650-fill power white duck down and 40% ultrafine PrimaLoft® fibers. This is wrapped in 3 layers of GORE-TEX® membrane and concealed with a highly durable polyester face fabric.


A high seat back and suspenders keep the piece in place to seal out cold in any position

Why are these not made in a small? Petite female hunters need warmth more than anyone.

I recently went on a spring Brown bear hunt in Alaska. As you know the weather can be quite drastic at time's. I used the Blizzard bibs heavily Along with the parka during the hunt. Crossing streams, rivers, deep snow and hail and rain daily I couldn't have asked for a better way to stay dry. This is a great product that can withstand heavy punishment. Thanks!

I recently tested many Sitka products on my recent hunt for Ibex in Kyrgyzstan. 15 degree mornings at 12,500' found me horseback in the Tien Shan Mountains on the border of China. The Blizzard Bib pants really did the job at these low temps. Comfortable to wear even over jeans to really keep you warm.

The new Blizzard Bib Pant seems well designed and surprisingly light. The only thing I cannot understand about the design is why the bottom of the pants does not provide a mechanism for tightening the fit to minimize air movement between the boot / leg and garment. It seems that with the design of the pant being for maintaining warmth that it should have a built in mechanism to tighten the fit. Am I missing something here? I think that Sitka is the best hunting gear there is for design and performance. I recommend it to any hunter I meet.
