Stay warm and still stand to pee.

Long underwear with an STP- and packer-friendly pouch, so you can pee without pulling your pants down. The cotton-spandex breathes and stretches for the gym, a run, under shorts, or as a cold-weather base layer.

Made for us by us.

  • A three-layer pouch keeps everything in place and low-profile under clothes.
  • The inner layer holds your STP, packer, or foam insert.
  • The middle layer guides the shaft through smoothly.
  • The outer layer has a button fly for quick access.
  • 92% cotton, 6% spandex

They're made to be worn hard. Train in them, travel in them, layer up, or lounge at home.

Cake Bandit sits low, on your hips, not your waist. Measure around the widest part of your hips and seat. Between sizes? Size down if you like a snug fit or pack heavy.

The long underwear has a longer rise than our other underwear, so measure your outseam too, from waist to ankle.

Size Hips Inseam / Outseam
S 27"–31" 22¼" / 32⅝"
M 32"–35" 22⅝" / 32⅝"
L 36"–38" 23¼" / 33½"
XL 39"–42" 23½" / 34¼"
2XL 43"–46" 24" / 35¼"
3XL 47"–52" 24⅜" / 36"

Our model Jussie (he/him) is 5' with 28" hips and wears a small.

Like another review said, they’re more like leggings than anything

That being said, I don’t think they’re necessarily bad—it’s an athletic material, but it’s not a bad base layer for folks with sensory issues/those who already run hot in the winter

Smaller than the boxers

I found that the long johns, while comfortable, are slightly smaller than the same size of the boxers. I felt that they slipped down very easily and I don’t feel comfy wearing them outside my house.

Order Long Johns but received jeggings

I thought I was ordering Long Johns but nothing about them appeared to be that. They looked like jeggings. Go back to the drawing board and rethink this item. Waste of money
