    Common questions

    Can I wear the leggings alone?

    Yes. Darker colours are best on their own, and lighter colours are best under clothes.

    Is it for sports?

    It is made for everyday warmth. For high-sweat sports, choose a technical base layer.

    How should it fit?

    Close to the body like leggings. Size up if you prefer it loose.

    Will it fit under jeans?

    Yes, it is thin enough for most regular-fit jeans.

    What size should I get?

    Fitted, close to the body. S fits US 4-6, M fits 8-10, L fits 12-14, XL fits 16-18. Size up if you like it looser.

    Can I mix colours or sizes?

    Yes. Choose a bundle, then pick the color and size for each one under “Mix and match” before you add to cart.

    How does Buy 1, Get 1 Free work?

    Pick "Buy 1, Get 1 Free" and you get 2 for the price of 1. The bigger bundles work the same way: 4 for the price of 2, or 6 for the price of 3.
