We designed the Ambient Jacket to be durable, packable, and most of all, adaptable to changing weather conditions and levels of activity. Utilizing low-bulk PrimaLoft® Evolve active insulation, this jacket delivers plenty of warmth when you’re still, breathes well and manages moisture when you’re moving and dries quickly if it gets wet. Ideal under a shell during cold weather hunts, on its own during brisk spring and fall evenings in camp, or tossed into your pack for summertime backpacking trips into the high country, there’s never a time when you don’t need this.

How to Take
Your Measurements
-
1. SLEEVE MEASURE
Bend your elbow and put your hand on your hip. Measure from the center of the back of your neck, along the shoulder and down the elbow to the wrist bone.
-
2. CHEST SIZE
Wrap the tape measure under armpits, around the fullest part of your chest. The tape measure should be snug, not so tight that it constricts breathing, yet not so loose that the tape measure slides down. Don’t puff out your chest. Stand relaxed while measuring.
-
3. WAIST SIZE
Measure your natural waist, which is the narrowest part of your abdomen, between your ribcage and hips. Stand relaxed while measuring.
-
4. HIP
For hip circumference, measure around your fullest point, approximately 8” below your natural waist.
-
5. INSEAM
In a standing position, measure from your crotch to where you want your pants to end, breaking at the top of the shoe in the front and just above the heel in the back.
-
6. GLOVES
With hand partially closed, measure over the knuckles and around the hand, excluding the thumb.
-
If Waist and Hip measurements do not match up on the chart, choose a size that is between the two to find the best fit.
Ex 1: If your waist measures 28” and your hip measures 40”, typically the best fit would be a size 29.
Ex 2: If your waist measures 27.5”, and your hips measure 38”, typically the best fit would be a size 28.

Technology


Why We Made This
Our goal was to create a layer that worked harder and performed smarter. The answer was in partnering with PrimaLoft® Evolve for the most active insulation on the market. Active insulation’s biggest benefit is its ability to adapt—it traps heat while you’re sitting, and breathes more efficiently than static insulation while you’re on the move. The Ambient jacket or hoody will increase the performance of your clothing system for any pursuit functioning as a mid or outer layer depending on the need.
The Ambient is the jacket I was waiting for from SITKA. This is the perfect active insulation layer that can stay on during all kinds of hunting scenarios from hiking in, to buffering a bit of wind / cold, to layering under something bigger. It breathes really well so I find I don’t have to take it on and off constantly which is awesome when you’re loaded down with a bino bivy and pack. Simply put, it’s a no-fuss performer. Sweat dries quickly, and the women’s fit is great with tons of mobility and stretch. Its light, and super packable. The solid color has become a go-to comfort layer for me too for at home and travel. Love this jacket
The Ambient Jacket checks several important boxes for me. Warmth without the sweat, and it’s quiet. It allows my body to breathe while climbing into the treestand and then keeps me warm while sitting still. Because of these features, I also find myself reaching for it for daily ranch work here in Missouri. It’s versatile and durable which make it a no brainer for me to keep on hand.
