Expert Reviews


What reviewers liked

Made from a poly-spandex material, the Thermajohn long underwear is decidedly lightweight, stretches easily, and offers full mobility no matter what your activity. It fits snug – almost like a second skin – but is soft.
We like these long johns because they’re comfortable and they work well for virtually any cold-weather scenario. There’s no need to find a pair of long johns that you have to change in and out of all the time!
Featherweight. Designed to be a four-way stretch. Thermajohn's slim fit design has excellent heat retention capabilities.
-
Won’t bunch. Due to the thin nature of the material these underwear are made from, the sleeves won’t bunch up like thicker clothes. This is great for people who like rolling up their sleeves while eating or other activities.
They are excellent for nearly any activity, whether indoors or outdoors. They are incredibly quick to dry, which will keep them from getting musty and damp under your ski pants and jacket. We love how they are incredibly soft and light, while still minimizing heat loss.

What reviewers didn't like
