Sitka 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.

Chest — 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.
Waist — Measure your natural waist, which is the narrowest part of your abdomen, between your ribcage and hips. Stand relaxed while measuring.
