Thermal Underwear Lounge Set

This is basically the answer to “how do I survive winter without freezing or looking like I’m wearing a sleeping bag.” The inside is lined with soft fleece that actually feels good against your skin, while the outside is smooth enough to layer under jeans, work clothes, or whatever without adding bulk or making you look puffy. It’s got stretch built in so you can move like a normal human, it’s machine washable without any annoying special care, and people are using it for everything from sleeping to skiing to just existing in their freezing apartment because heating bills are insane. Comes in multiple colors, runs true to size, and holds up after multiple washes without turning into sad, flat fabric.
