We like to have a good pair of thermal underwear to go camping in the cooler months. This underwear is very soft and comfortable. I ordered a size medium and it fit me nicely. My husband ordered his normal size and he did not have any sizing issues either. These will definitely keep you warm. We’re going to really enjoy having these on our next camping trip. – Hip Sidekick Melissa


I ordered this thermal set mainly to wear under layers during my son’s high school baseball games this spring, which tend to be freezing and windy. The material is buttery soft and so comfortable. I fell between Medium and Large on the sizing chart but chose the medium because I preferred it to be more fitted and didn’t want it bunching up under my clothes.

It fits perfectly. The material is very flexible and stretchy, and so comfortable. I haven’t tried the pants on yet under jeans, but they aren’t super thick, so I’m not worried. I even wear this set around the house on really cold days. I love this set and will be wearing it a lot this winter. Highly recommend. ⭐️⭐️⭐️⭐️⭐️

I had previously purchased my husband some traditional long johns to wear for work under his clothing. Then I saw these and decided to give them a try. My husband fell so in love with these because they are soft, thick, and warm. he even uses them as PJs. He did not care for the other thermals after trying these! ⭐️⭐️⭐️⭐️⭐️

I wore this as a base layer on a trip to Antarctica. It is very light and thin enough that I could wear it as an undershirt inside without overheating, but I also didn’t get cold while I was outside while wearing a light sweatshirt and a windbreaker.

I love that this has a scoop neck on it – frequently base layers like this have really high necks so you can’t wear them under shirts without having them show. Not an issue with this shirt! ⭐️⭐️⭐️⭐️⭐️

I love the INNERSY Women’s Lace Trim Hipster Panties! They are super comfortable and stretchy, with a flattering low-rise fit. The lace trim adds a nice touch of sexiness, and the cotton fabric feels great against the skin. The 3-pack is a great value. ⭐️⭐️⭐️⭐️⭐️
