| M | 31–33 in | 37–39 in |

Questions before you buy
Packing Underwear FAQ
Which style is best for a first-time packer?
Packing boxer briefs are usually the easiest starting point because the support is built in. If you prefer wearing your own underwear, an FTM harness may be a better choice.
Can I use STP underwear with every STP device?
Compatibility depends on the size, shape, and cup design of your STP. Always check the product description and practice at home before using it outside.
Should I size down for a firmer hold?
If you want a stronger hold or use a heavier packer, sizing down may help. If you prefer comfort for all-day wear, choose your regular size or size up when between sizes.
Can packing underwear be returned?
Because underwear is a hygiene-sensitive product, returns may be limited. Please check your store’s return policy before ordering.
