My Favorite Insulated Jackets for Hiking & Backpacking (2026)
Insulated jackets are a key component in a good layering system for hiking. When choosing jackets, I look for options that are lightweight and pack down small so they are easy to stash in a backpack.
Features to Look for in Insulated Jackets
Type of insulation: Both down and synthetic insulation have their place. Synthetic insulation performs better in rainy or humid conditions and retains warmth when wet. Down insulation is typically warmer for its weight and compresses smaller, making it easier to stash in your pack.
Fill power: A measure of how much space one ounce of down fills when it’s fully lofted. Higher fill power means the down is fluffier and traps more air, providing more warmth for its weight and taking up less space when compressed. Most premium outdoor gear uses 800-1,000 fill-power down.
Fill weight: The total amount of insulation used in a jacket, whether down or synthetic. A higher fill weight generally means more insulation and potentially more warmth, although warmth also depends on the type of insulation, jacket design, and how evenly the insulation is distributed.
Hoods: Hoods keep your head warm without the hassle of a separate hat, making them easier to manage on the move while better protecting your neck and ears, as well as blocking wind.
Ventilation: Ventilation features such as pit zips and underarm perforations make it easy to dump excess heat without fully removing the jacket. In addition to unzipping the front, opening the pockets can also provide a small amount of airflow.
Pockets: Pockets are essential for stashing gloves and small items. Pocket placement matters, too — higher pockets are usually easier to access while wearing a pack, since you don’t have to unbuckle a hip belt (though this can vary depending on torso length). Chest pockets are useful for keeping your phone close at hand and easy to access.
Sleeves: This feature is often overlooked, but I prefer longer sleeves that extend over my hands for added warmth and protection. Thumbholes are a bonus — they keep sleeves from riding up when layering and provide extra warmth without gloves. I also look for elastic cuffs that seal out the elements without feeling too tight.
Packability: An insulated jacket should compress well and take up as little space as possible in your pack. This leaves more room for the rest of your gear while still allowing you to carry a warm layer for breaks or colder temperatures.
Weight: I look for options that weigh less than a pound, helping keep overall pack weight down without sacrificing warmth.

Outdoor Vitals NovaPro Jacket

I especially like how small it packs down, making it easy to carry for cold-weather breaks or camp.

An adjustable hood and roomy pockets round out a jacket I find especially useful in very cold, windy weather.

I’ve worn it on many winter camping trips on the Oregon Coast, where the weather tends to be wet and windy, and it has kept me plenty warm.

Enlightened Equipment Torrid Jacket
The lightest jacket listed here, the Torrid is impressively warm for its weight. A favorite among thru-hikers, its design is very simple, with a boxy fit, two hand pockets, and a hood.

The jacket is available in either a stock version or a custom version, with multiple color and fabric options to choose from. My jacket uses 10-denier fabric on both the inside and outside, though a more durable 20-denier fabric is available for the exterior.
