The Best Winter Hiking Jackets with Synthetic Insulation of 2020


Black Diamond First Light Hoody

Low temperatures are no obstacle for hiking if you dress appropriately to stay warm and comfortable. An insulated jacket is one of the most important pieces of winter hiking clothing because it reduces your body heat loss by trapping the body-warmed air within its insulation. Insulated jackets also offer some basic protection against rain, snow and wind – depending on face fabric and the insulation material (down or synthetic). Below we selected the best winter hiking jackets with synthetic insulation. Jackets with synthetic insulation differ from down jackets by providing good warmth even if they get exposed to moisture (rain, snow, high humidity etc.) – which makes them more versatile. They also dry faster and are less expensive than down jackets. However, down jackets offer a better weight-to-warmth ratio and pack smaller.

In this selection we only listed jackets that are lightweight and very warm. If you are planning to mostly hike in cold but dry conditions, we recommend that you instead check out our selection of the Best Down Jackets. For those who are looking for an insulation layer for more moderate temperatures we have also made a side-by-side review of the Best Fleece Jackets.

We regularly update our reviews and selections to always recommend you the best products on the market.

1. Buying a Winter Hiking Jacket with Synthetic Insulation – What is important?

Insulation:

Synthetic insulation is in most cases made of fluffy polyester fibers which mimic the structure of down clusters. The polyester fibers are of different sizes to create loft so that the body-warmed air can be efficiently trapped into small air pockets between them. As polyester absorbs very little moisture (maximum 0.4 % of its own weight), polyester-based synthetic insulation retains its loft (and thus warmth) even if it gets exposed to rain/moisture. Some manufacturers develop their own synthetic insulations – for example Arcteryx (Coreloft) and Mountain Hardwear (Thermal.Q) while others use high-quality insulations from brands such as PrimaLoftG-Loft, Polartec and Climashield.  Normally a high-quality synthetic insulation can provide similar warmth to a 600 fill-power goose down. For more information about insulation materials, check out our article Comparison of Mid-Layer Materials. If you are not sure whether to buy a jacket with synthetic insulation or down jacket, check out our article Down vs Synthetic Jackets.

Face Fabric:

The face fabric of an insulated jacket should provide good abrasion-resistance as well as basic protection against the rain and wind. Therefore, the face fabric is usually made of nylon which is treated with DWR (Durable Water Repellant) so that it repels the water instead of absorbing it. Nylon can have different denier values – the higher the number, the heavier and more durable the fabric. Some insulated jackets also utilize a wind-blocking or waterproof/breathable membrane in their face fabrics for increased weather protection. Read our article Comparison of Shell Materials for more information about face fabrics. To learn how to properly layer your clothes for hiking check out our Hiking Clothing Guide.

Weight:

The weight of an insulated jacket greatly depends on the quality of the insulation (warmth-to-weight ratio) – if the insulation is of low quality, more of it is required to provide good warmth. In this review of the best winter hiking jackets we only listed jackets with a good warmth-to-weight ratio as lightweight clothing and equipment allow you to hike faster and more efficiently. Learn more about this in our article Why hike lightweight.

Hood:

When it comes to choosing between an insulated jacket with or without a hood, you need to consider how much you would actually use the hood. A hood offers additional insulation and does not increase the weight of the garment significantly. However, hooded versions are usually slightly more expensive.  This review of the best winter hiking jackets includes four hooded jackets and one jacket which is available with or without a hood.

Pockets:

A winter hiking jacket should be equipped with well-placed pockets for storing essential items. Pockets should allow easy access even when wearing a backpack or a climbing harness.

4. Questions and Answers

How to wash an insulated jacket?

Insulated jackets can typically be machine washed at 30 C. However, you should skip the spin cycle and let the jacket drip dry. You should not use the fabric softener or tumble dryer.

What is the best jacket for extreme cold?

In extremely cold conditions we recommend wearing a down jacket because down jackets have the best warmth-to-weight ratio. However, note that down jackets are only suitable for dry conditions. In humid or wet conditions you will be better off with one of the jackets listed above (using synthetic insulation).

What fabrics to wear in winter?

In winter you should wear a long-sleeved base layer made of either Merino wool or polyester under an insulated jacket. Insulated jackets utilize down or synthetic insulation. We also recommend wearing pants made of softshell fabric, insulated gloves and polyester fleece headwear.
