Jockmail Packing Briefs

by Jockmail

Your new favorite packer underwear. Jockmail Packing Briefs come with a special pouch for your packer. This pouch keeps your packer nice and tight against your body. Plus the cloth barrier prevents your packer from chaffing your sensitive bits.
Jockmail Briefs also come with a removable soft foam insert that you can use instead of a packer. This is great for guys who don't have a packer or who don't want an anatomical bulge. Of course, you can always remove the soft foam insert and drop in your favorite packer. The pouch is big enough to fit most packer sizes but small enough to keep your packer secure. Made soft with a combo of 92% cotton and 8% spandex.

Jockmail underwear runs small. Do NOT order your "normal" size underwear. We also don't recommend ordering your regular jeans size. Jockmail is low rise and sits on your hips and not your true waist. Instead, measure the part of your hips just below your hip bones and consult the guide below for correct sizing. If you have bigger thighs, we recommend choosing the jockstrap or brief models as the legs can also be a bit tight. If you are unable to measure, we recommend you order 2 full sizes above your normal size

MEDIUM - 27-29"

LARGE - 30-32"

EXTRA LARGE - 33-35"

XXL - 36-38"


Wash in cold water. Drying this product in the dryer will result in normal cotton shrinkage. If you'd like to minimize this, your Jockmail underwear can be air-dried.

Some of my new favourites

I love them, but when I pack with them they’re too high. I use a jockstrap with them and adore them though, I’ve ordered them before and will order them again!

Great butt….

The design is great but your ideas on sizing need to be expanded.

Pretty good, but not really cut for AFAB bodies

I’m pretty sure this company just uses the pattern for their regular men’s undies and then adds a sewn-in pocket to these ones. This means if you have thick thighs, the leg holes might be tight and cut in. Otherwise they’re pretty comfortable, just be prepared to size WAY up (I normally wear a M/L in men’s boxers, the 2X in this brand JUST fits me).

Pretty good

They’re pretty good underwear but your sizing is way off, I’m usually a medium, I got a large, and it was still too small. It’s not unbearable but your sizing chart is definitely off.

Runs INCREDIBLY small but otherwise great

I usually wear a men's XS in American clothes. I bought a size M and it is still too small. These must be Asian sizes, because the M is literally the equivalent of an XXS. So for me, I needed to have ordered THREE SIZES UP. Just be aware. At 5'3" and 100 pounds, I am apparently a size LARGE, according to this manufacturer.

Otherwise, love it. I have severe fibromyalgia and pressure urticaria and can't use many packers or harnesses as a result. These are great because they distribute the weight of the packer over a larger area of your body. They also simply do a much better job of keeping your dick in place than anything else I've tried. The dick pocket goes down low enough that the balls can actually be underneath you as they are supposed to be. Love that these came with a packer form as well...already had a few but you can never have too many!
