Undies

URSA Undies are a smart, lightweight alternative to traditional Straps and Belts. Created to solve challenging transmitter placement needs under tight wardrobe. Made from soft jersey Lycra that feels like regular underwear with stretch (but not compression like URSA Shorties) meaning performers stay comfortable while packs stay secure. 

🩳 Unisex Lightweight Design

• Worn like regular underwear with a soft, breathable feel.

• Created for Film & Theatre where secure, non-slip rigging under wardrobe is essential. 

🔁 Infinity Loop Waistband

• A continuous sideways rigging loop around the waist lets you place a transmitter anywhere along the band for optimal concealment. 

🦵 Multiple Leg Placement Options

• Two Thigh Loops: Allow sideways rigging around either thigh — front, side or back — depending on comfort and costume. 

• Two Inner Leg Popper Pouches: Vertical pouches with popper closures let you secure a transmitter on the inner leg (up or down orientation). 

🔌 Cable Access & Management

• Thoughtfully placed access holes on both thigh loops make routing mic cables easier and keep them out of sight. 

👖 Works Under Shorts, Trousers & Tight Costumes

• Designed to sit no higher than the trouser line and address common wardrobe problems, making transmitters fully hidden with minimal bulk. 

📡 Universal Transmitter Compatibility

URSA Undies support a wide range of wireless transmitters, though they’re best suited for small to medium‑sized packs like the Wisycom MTP61, Lectro SMB or Sound Devices A20Mini.
