If you're going for trekking, you'll need a good pair of socks. By that, we mean a woolen or synthetic blend. Some might also prefer wearing another layer of thin, lining socks under the heavy pair.
Gloves are also an important accessory and can be used for both summer & winter treks. Use UV protected gloves if you're heading off to a warm region like the desert. For cold regions, you can use shell mittens or ski gloves, depending on the temperature. You can click this link if you want to buy various hiking gear.

Choosing the right set of clothing ensures that you feel comfortable & protected. So, the next time you're headed for an adventure, remember to select your hiking apparel well in advance.
Also, trousers aren't your best friend where there's a trek involved. Choose convertible pants. This refers to the second layer of clothing and is a must-have if the temperature is substantially low. Fleece tops or t-shirts is a great option for both men and women. It's a breathable fabric that keeps you warm.
It's particularly helpful if you've been exposed to rains or damp moisture. You can also add another layer of insulated jacket or vests. However, make sure that the jackets are light-weight. Synthetic wear can help on that account. You should also keep an eye out for washable garments.
