Best thermal wear in India

Merino wool thermals

If you are new to layering and would like to know more about the best thermal wear in India or more about different woolen winter wear, then you have come to the right place.

What do you like about winter the most? The sparkly snow, the crisp wind, the snuggly mood, the whisper of holidays, or (wait for it…) that warm hug of hot chocolate? I know. There are so many things to love about winter. But do you know I was not a fan of winter until very recently? Main reason? You guessed it, the cold. 

As someone who was not gifted with tough skin(literally), it was common for me to start shivering as soon as the first winter breeze blew. So what changed? Well, I did my research and found out about winter layering and the basics of winter clothes. I discovered the cozy world of thermals and it has never been the same. 

Best thermal wear India – How to choose the best woolen thermal wear in India?

Alright. Let us start with the basic question. What exactly is thermal wear? 

Thermal wear, also known as the base layer is a piece of clothing that is worn over your undergarments that offer protection against cold. It is the first article in the winter layering system, followed by your mid-layers- hoodies and pullovers, followed by your outer layer – the likes of jackets and coats. You would also need accessories- gloves, socks, and mufflers to protect your extremities from cold. 

Now that we have covered the basics, let us dig a bit deep in. Why is thermal wear so important?

Let me give you an example. Imagine you are in the Himalayan valleys trying to get ready for your awesome trekking experience. Usually, in the Himalayan trekking expeditions, you would have already been covered in your woolen thermal wear, followed by the mid-layer of your choice and a snow-proof hardshell jacket for warmth. 

Now, let the trek begin. As you can imagine trekking is an activity that would require some energy and at some point, you are bound to start sweating even in the cold temperature. So, what you need in this scenario is a set of clothing that is quick-dry, moisture-wicking but at the same time non-compromising when it comes to keeping your body warm. If not, you would be covered in sweat under your layers which can not just be absolutely uncomfortable but also itchy, and even lead to serious health conditions like hypothermia. Now that is exactly where your thermal or base layer comes into play.

Warm Thermal Wear

Warm Thermal Wear

The primary duty of thermals as you might have already deducted from above it to keep your body warm and dry- dry being the keyword. Since the base layer is worn above your undergarments it is closer to your body and needs to be capable enough to absorb the sweat quickly and dry even quicker. 

Wool is among the favorite choices of designers when it comes to thermal wear. Due to the fabric structure of wool, it has the innate ability to trap air between its fibers easily as compared to other fabrics like cotton. Woolen thermal wear also guarantees quick moisture-wicking but pure woolen fabrics often lead to itchiness.

 Kosha, the Mumbai-based winter and travel wear brand, founded in 2017 invented a unique fabric composition to tackle this problem. They merged merino wool, one of the most sought after and premium wool in the industry with bamboo, to come up with an organic blend that is extremely moisture-wicking, facilitates rapid drying, is temperature regulating, lightweight, and odor-free.

One of the reasons it can be regarded as the best thermal wear in India is because of how effectively they provide warmth up to -20℃ with appropriate layers to accompany them. They are also sustainable and have an eco-conscious packaging approach.

Now that you have an understanding of base layers or thermal wear, here is my list of the best thermal wear in India. I have also included other layers that can keep you warm with your thermal wear to offer a complete package of winter layering.

Kosha Woolen Thermal Top 

Let me start from the top (literally). 

When you are out in the cold, choosing the best thermal top can make a huge difference for your entire trip. Depending on the temperature, your thermal wear should be able to modify its capacity in keeping you cold. You do not want to start sweating and feel your armpit wet when you enter a cozy tea house just because you are wearing your woolen thermal wear. You would want something comfortable that can keep you warm but not too warm. 

Something comfortable but not too snug. Breathable and soft on the skin. The thing about the base layer is that unlike all other layers(hoodies, sweaters, or jackets), it is difficult to remove the thermal just because you are hot. You will have to remove all your other layers to remove your base layer and that too if you did, it would be difficult to carry out. So your thermal top needs to be lightweight, quick-dry, and easy to carry.

Merino Wool Bamboo Blend Thermal Top

Merino Wool Bamboo Blend Thermal Top

Kosha’s merino wool and bamboo blend thermal top is one of the most multifunctional thermal wear available out there. It is designed in such a way that it can be worn not just as thermal wear but also as a T-Shirt when the situation demands. If you are out on a winter day at 10℃, Kosha’s thermal top would keep you warm and dry with the layers. But if you are feeling hot, you can always remove the layer and wear the thermal on its own.

The design and attractive colors(olive, sky, blue, oatmeal, wine red, etc) that it comes in make sure that you would not stand out but rather look like you are out on a day in your regular Tee. 

You can wear the same thermal at 20℃ or -10℃ with layers. It is also antibacterial, odor-free, and a fabulous fit. You can also have your pick between half and full sleeves from the website.

Another great thing is that they come in a cute sustainable package made of undyed organic cotton. This not just helps in reducing their carbon footprint but also makes a great convenient way of carrying them during travel.

Kosha Woolen Thermal Bottom

Now that the top is covered, it is time for us to talk about the bottom.

Comfortable Woolen Thermal Bottom

Comfortable Woolen Thermal Bottom

One thing that I always miss when thinking of thermals is to look into the thermal bottom. It is as if I think of my bottom half as cold-proof(just kidding!). But in reality, we often forget to invest in foolproof thermal bottoms when purchasing winter wear. Jeans or denim material can offer you protection till around 15℃ but anything below that would ideally require you to wear a woolen thermal bottom.

Thermal bottoms or leggings are that you can wear underneath your normal bottom wear to protect your legs. Just like the thermal top, they need to be skin-friendly, must be able to absorb moisture fast, and have efficient temperature regulating properties. 

Since you would be layering yourself with normal clothes, the fit of the thermal bottom is also important. You do not want something that is saggy or too fit that stops you from breathing. You would need something that can hug your body comfortably and at the same time provide room for movements. If you are into adventure or activities, choosing a thermal bottom that is flexible and movement-friendly is very important. 

Kosha’s thermal bottoms are made of the same blend of merino wool and bamboo. The presence of elastance in small quantities in the thermal bottom helps in acquiring that flexibility needed without suffocating the body. They are also very lightweight, anti-bacterial, and odor-free. Apart from the standard colors of black and white, Kosha’s thermal bottom has also explored other colors like oatmeal, blue, olive, charcoal, and so on. 

Just like the woolen thermal top from Kosha, the thermal bottoms also come in a travel-friendly organizing packaging that contributes to making your next adventure pleasurable without harming the environment.

Kosha’s On the Go Hoodies & Supima Pullovers

As I had denoted before in the previous section, thermals work well when they are layered properly. The main purpose of thermal is moisture-wicking, so if you are at a temperature below  10℃, just wearing a thermal might now help. You will have to add layers to your winter apparel to feel comfortable. 

Stylish Pullover for your best Thermal Wear

Hoodies and pullovers are part of the mid-layers in the winter layering system. They are worn after the thermals are worn. It is not mandatory to wear your Hoodies or Pullovers when you are wearing a base layer. The purpose of wearing a mid-layer is to add extra warmth. They are the ones who are in charge of trapping the warmth by providing extra layers between your body and the outside.

On the go hoodies from Kosha is one of the multipurpose hoodies that can be used not just with the base layer but also worn as an all-weather comfort layer. Made in 100% organic cotton, they are super soft and can make you feel warm at normal temperatures.

Another piece of mid-layer item from Kosha that can be teamed with your base layer is the Supima pullovers. Supima is a premium cotton brand that has superfine fibers which give the fabric a silken texture. They are an excellent addition not just as a mid-layer but also as a comfortable pullover that can be worn for your work-from-home days, or staycation plans. 

The bright and attractive colors of the pullover make it extra tempting to be donned as a fashionable piece on its own.

Hoodies and pullovers might not be for everyone. Some people like to keep it a bit formal at events with a well-knitted woolen sweater over their woolen thermal wear. Sweaters are part of the mid-layer winter wear which helps in trapping the heat of the body from escaping. 

Used for warmth, sweaters followed the traditional path of woolen fabric with bland colors.

Good woolen accessories can work wonders in not just providing warmth but also can elevate the look as such.
