Pakcing Underwear

Gender-Affirming Underwear Built for Real Bodies

This is the underwear drawer you always deserved. TGS carries packing-compatible underwear, STP-ready briefs, boxer briefs, and gender-affirming styles designed specifically for trans men, trans masculine, non-binary, and gender expansive people, with real function built into every pair.

Whether you're packing daily, just exploring what works for your body, or looking for styles that fit the way you actually want them to, this collection covers the full range. Cake Bandit briefs and boxer briefs lead the lineup with a built-in front pouch engineered for packers and STP devices, while additional styles from TGS's curated brands offer fit-first options across all body types.

Every style in this collection is chosen for comfort, durability, and body-affirming design — no awkward workarounds, no products adapted from cis-normative cuts. Just underwear that respects your anatomy and your identity, in sizes that actually fit.

Pair with a packer or STP device from TGS for a complete, integrated setup.
