When most people think of Southern California, images of endless sunshine and warm, sandy beaches often come to mind. And while we certainly get our fair share of beautiful, sunny days, those of us who venture into our local mountains or explore the deserts during cooler months (or even just after sunset!) know that SoCal can also deliver some genuinely cold conditions.
From crisp autumn mornings and chilly desert nights to bona fide snowy winter wonderlands in our higher elevations, being unprepared for the cold can quickly turn an exciting adventure into an uncomfortable or even unsafe experience. That’s why having the right warm gear and a smart layering strategy is just as important as your sun hat and shorts are in the summer. Here’s our approach to staying warm and comfortable when exploring SoCal’s cooler side.

The Foundation: Thermal Base Layers
When the temperature drops, what you wear closest to your skin is your first line of defense against the cold.
- Men’s Thermal Set: We’ve found that you don’t need to spend a fortune to get effective thermal underwear. These UNIQUEBELLA Men’s Thermal Underwear Sets (which include a top and long johns) are relatively cheap but provide good warmth. They are fleece-lined, sweat-wicking (quick-drying), and make for an excellent thermo base layer on cold days. (Ladies, look for similar lightweight, moisture-wicking thermal base layers designed for women!)

Okay, here is “Blog Post 5” in our established style, focusing on gearing up for Southern California’s cooler hikes and winter conditions.

Essential Warmth: Insulated Winter Coats
A good quality, insulated outer jacket is crucial when you’re facing truly cold, windy, or even wet winter conditions.
- Women’s Winter Coat: For winter hikings, we’ve been impressed by the wantdo Women’s Hooded Winter Coat. It’s surprisingly affordable, yet it’s waterproof, warm, long (which is great for extra protection), and has a lot of “smart” details like well-placed pockets and an adjustable hood that make it very practical on the trail.
- Men’s Winter Coat: There’s a very similar and equally effective option for men, the Men’s Winter Coat Waterproof Warm Insulated Thicken Long Down Jacket with Hood. Just like the women’s version, it boasts those “smart details” and provides excellent warmth and protection without a hefty price tag.
Little Lifesavers: Hand Warmers & Other Warmth Boosters
Sometimes, it’s the little things that make the biggest difference in comfort when it’s cold.
- Hot Hand Warmers: These are a non-negotiable for us in cold weather. The Hot Hand Warmers (11 Hours Long Lasting – 40 Count) are fantastic. They are natural, odorless, safe, single-use air-activated heat packs that provide up to 11 hours of heat. We find them especially useful when it’s cold in a tent at night, or just to pop into gloves or pockets during a chilly hike. They are also TSA approved, so handy for travel too!
- Extra Tip – The Versatile Wool Blanket: For serious cold, whether on the trail during a long break or back at a chilly campsite, an item like the Arcturus Military Wool Blanket (which we talk more about in our “Campsite Comforts” post) can be an incredible warmth booster.
Don’t Forget the Mid-Layers!
A good winter coat and base layer are vital, but what goes in between is just as important for a flexible layering system that allows you to adapt to changing conditions and activity levels.
- In our “Head to Toe: Essential SoCal Hiking Apparel & Footwear” guide, we talked about versatile options like the Fruit of the Loom Unisex Fleece Hoodie and the Amazon Essentials Men’s Polar Fleece Shirt Jacket. These types of fleece jackets and hoodies become absolutely essential mid-layers when you’re building your cold-weather system. They trap heat effectively and can be easily added or removed as needed.
Accessing Winter Wonderlands: A Note on Mountain Travel
If your cooler SoCal adventures take you into the mountains during winter where snow and ice are a distinct possibility (like parts of the San Gabriels, San Bernardinos, or San Jacintos):
- Remember that trail conditions can be very different, and additional safety gear (like microspikes or snowshoes, not covered here) might be necessary.
- Importantly, road conditions can also be challenging. In our “Beyond the Trailhead: Equipping Your Car” post, we discuss essential car safety gear like Snow Chains, which are often mandatory for mountain travel in winter. Always check current conditions and requirements before you head out.
With the right gear and a smart approach to layering, exploring Southern California’s beautiful trails during the cooler months and winter season can be incredibly rewarding. The landscapes take on a different kind of beauty, the trails are often less crowded, and there’s a wonderful crispness in the air.
So, don’t let the thought of cold weather keep you indoors. Gear up, stay warm, and enjoy the year-round adventure SoCal has to offer!
