Thermajohn Lightweight Tagless Thermals Set

Whether you’re going to spend a day out skiing on the slopes, hiking in the brisk weather or working in the yard, wearing a good pair of thermals underneath your clothes is the key to being comfortable and warm. Thermals not only help your body heat stay at the right temperature, they are also good for wicking away moisture so your body feels dry.

When you’re looking to buy a set of thermals, begin by thinking about the function you want them to provide. For example, if you will be active while wearing the thermals, you may begin to sweat, so find a pair of thermals that is designed to wick away moisture to avoid feeling damp with sweat. Getting thermals that are stretchy is also key if you are going to be active, so that you have a full range of movement in your clothes. If you won’t be able to shower or change clothes frequently, such as when you’re on a hiking trip, then it’s important to find thermals with bacteria-resistance properties.

If you’ll be outside in particularly chilly temperatures, look for thermals that are made from heavy fabrics. Low-density weaves are important for trapping warm air close to your body to keep you toasty and insulated.

Synthetic materials such as polyester, lycra, nylon and spandex are mixed with natural fibers for thermals that can stand up to extremely cold weather. They can also wick away moisture while retaining heat. Thermal underwear that is made of wool is also a great fabric option for moisture-management.

If you’re going to be highly active in moderately cold weather, opt for thermals made from silk, which has a luxurious feel and soft texture. Cotton thermals are an affordable option, but they are not as warm as other fabrics, nor are they as good at wicking away moisture.

• Getting the perfect fit for your thermals is key. If it’s too tight, it will feel restrictive and it won’t provide a full range of movement. If it’s too loose, you will look bulky with a large layer underneath your clothes. Ideally, thermals should fit like a second skin, so that it insulates your body without having any extra fabric. A snug fit not only looks good under your clothes, it also traps heat that your body generates and doesn’t let it escape. This leaves you feeling warm and toasty in chilly conditions.
• There are many different types of thermals, such as T-shirts, pants, long-sleeve shirts, briefs and even full-body suits. The type you need will depend on the function you want it to provide. Keep in mind that while one-piece suits are excellent at keeping you warm, they can be difficult to maneuver when you need to use the bathroom.
• When buying thermals, comfort is of the utmost importance. Opt for thermals that don’t have seams or those with seams that sit completely flat. Because thermals are worn so close to the body, an abrasive seam can cause irritation on your skin if you’re wearing the thermals for an extended period of time.
• If you haven’t worn thermals before, you may be wondering how they will fit under your pants. The key is to have a lightweight fabric that fits snugly on your body. Pull the thermal waist up above the waistline of your pants so that you can do up your pants with ease.
