Layering is essential to stay both warm and dry, but not hot and sweaty, when walking in cooler weather. From the base, you need a shirt that will draw away any moisture, a jacket or vest to insulate and cut the wind, and a waterproof layer if you are in a wet climate.

This long-sleeved turtleneck is great for cool weather walks. The wicking fabric is far superior to cotton for keeping you dry yet insulated from the chill. I wear a similar long sleeve technical t-shirt on all of my cool walks - it's perfect under a wind-resistant or waterproof jacket. The antimicrobial finish helps keep odor away. It comes in plus sizes 1-4.

© PricegrabberI learned at the start of my walking career in the rainy Northwest that you need a waterproof, windproof shell jacket for walking and hiking. Underneath that, you can wear a fleece vest or fleece jacket on colder days, over a sweat-wicking shirt. This trail jacket is lightweight, breathable and packable. It's a great jacket for walkers who don't want to come in out of the rain. It comes in plus sizes 1X-3X.

It comes over the hip but has a tailored profile so it won't get in your way when you move your arms or use fitness walking poles, and is easier to layer under a waterproof jacket. It has two zip pockets in front and two inner patch pockets. Wear this over a base layer shirt on cool and dry days, or wear as the insulating layer beneath a waterproof/windproof jacket and over a base layer shirt on cold and wet days. It comes in plus sizes 1X-3X.
