    Welcome to the most comfortable undies on the planet. Handmade locally by Wonderpants, our lovely neighbour here at the Mill Castlemaine :) 

    As one of the lucky product testers of the new Wonderpants merino undies we can fully vouch for the superior comfort of Wonderpants Merino underwear! 

    Merino wool makes so much sense next to our skin. Especially when it comes to socks and jocks. The wonderful properties of merino wool with its amazing breathability, moisture wicking, odour neutralising softness really comes into its own.


    The Wonderpants Merinos are elastic free for comfort, there is however 6% elastane in the fabric instead and we can testify they are not the type that fall down!

    Sizes: S, M, L, XL, XXL **See more on sizing below

    Colour: Navy, Cream (Black no longer available sorry)

    Fit: If you like the feeling of a relaxed fit, go with your usual size. If you like a more firm fit size down. See the size chart in the product images if still in doubt.

    Fabric: 94% NZ and Australian merino wool, 6% elastane. Elastic Free. 

    Care: Wool machine/delicate wash cold-30 degrees or handwash. Drying time: super fast!

    Made in Castlemaine by Wonderpants.

    More on sizing: 


    Wonderpants are a generous fit - or we like to think, a ‘real’ fit.

    It’s possible you may go down a size compared to what you normally wear.  Use the Size Chart measurements pictured as a guide.

    If you fall between two sizes, or are unsure, think about how you like your underwear to feel and fit. If you prefer a firmer fit, go for the smaller size. If you prefer a more comfy fit, go for the larger size.

    Wonderpants merinos have a higher top. The High-top cut provides a roomier fit. With this in mind, I would recommend you choose the smaller size if you like a firm fit.
