The Thongkiller - Long

Sale price Price $ 29.99 Regular price

This bikeshort length Thongkiller is perfect for lounging, mild shaping, and getting rid of thigh chafing. Wear it under dresses and skirts to avoid wardrobe malfunctions. It's supremely silky, stretchy, and comfortable - like petting a kitten while drinking a chai tea.


Our favorite briefs, now in a longer length. Perfect for kiling VPL and banishing thigh chafing. Think: a silky embrace, gentle smoothing for lovable tummies and a modern design inspired by men's briefs. Add in the whole sweat-wicking, quick-dry, antibacterial thing we do so well and this might be your next great love.

Underwear for Everywhere

Silky and comfortable.

You'll feel like you're getting silky hug. SOMI is designed so that it's comfortable enough to be worn under clothing all day but strong enough for swims and hikes.

Stay fresh and dry.

The secret sauce is in the fabric. Sustainluxe wicks sweat, dries in a snap, and is anti-microbial to keep you fresh.

    Undies that multitask.

    Never forget to pack a swimsuit again. Minimalist designs and performance fabric means you'll fit in wherever you go. UV and chlorine resistant.

    Ships in a reusable mailer.

    "I especially love that the box is reusable and simple enough that i can use the box for other things. It's the perfect size for keepsakes!" Sarah B.

    "This brand is a solution to a HUGE need I have when traveling and packing."

    I recently took my SOMI’s with me on a 25 day trip around 8 states in the west and was able to go from hiking in them, to hot springing, to lounging, to working, while also being able to wash and care for them with ease on the go. Perfect for my minimal and on the go lifestyle. They dry quickly, feel incredible silky-soft, are comfortable, odor resistant, and are SO CUTE on. -- Kymberly Flores
