Just as Advertised

Not the softest, but definitely the smoothest. I can comfortably wear these pants without underwear. I love how even the design is based in atavistic techniques, like not attaching drawstrings, buttons, elastics, or zippers; just a simple and much less fussy design. They are definitely warm, but relatively neutral feeling in hot weather. I do not like, however, that mine were shipped in plastic bags for some reason. I got mine in a bigger size to accommodate more room, but this does come at the risk of sagging if too many things are sitting in my pocket (not a negative, an observation).

Hi there! Thank you so much for your feedback! We’re glad to hear that you find the pants comfortable and appreciate the design.

We're sorry to hear about the bags—most of our packaging is made from compostable material, so it’s surprising to hear that yours arrived differently. We’ll look into this to ensure consistency in our packaging.

Thank you again for your observations and for sharing your experience. If you have any other questions or need further assistance, feel free to reach out!

New favourite pants! Incredible

These alpaca sweatpants redefine comfort. soft, supple, but with a feeling of weight and strength. they breath when it is warm, they keep me warm when it is cold.
i can't take them off.
and i love that there are no plastics or chemicals.

Amazing

Love the feel and fit of this well made piece of clothing. Super strechy and comfortable. Feel warm and breathable and well constructed.

It's great to know that you find it super comfortable, and well-constructed while providing warmth and breathability. If you ever need anything else, just let us know! :D

Great product- 420 midweight sweatpants

Thank you for your preference :D

Perfect for a slim athletic fit.

Keeps me warm and is anti-stinky. I use it after my boxing workouts. And sometimes during. It can stay fresh and clean for a while. Well made and worth it.
