    My new fave pjs!

    These pajamas are comfy, lightweight and silky and have quickly become my new favourite pjs. As someone who suffers from hot flashes & night sweats, I usually have to forego pajamas, and these are the first pjs I've found that I can actually wear to sleep in - even though they have a full sleeve. They're so soft and lightweight that it's almost like not wearing anything. They're super comfy for pajama days as well, and I love the khaki green colour.

    Beware that because of the close drape of the fabric, they don't conceal much, but I went up a size to an XL because I had read another review stating such, which has helped. I prefer a flowier pajama anyhow.

    So Comfy

    I love this sleep set. I bought one last year in ivory and this year I bought another set in the Wintergreen colour. It machine washes and dries beautifully. It feels luxurious and is so comfortable to sleep in.

    Love them!

    These pajamas are hands-down the most comfortable I’ve ever owned. The fabric has a beautiful drape that feels soft and flattering, without being clingy. They somehow manage to keep me warm in the winter yet cool in the summer, which makes them perfect for year-round wear.

    I find myself reaching for them constantly—they’ve become my go-to for lounging, sleeping, and even just relaxing around the house. The quality holds up well with regular washes, and they still look and feel like new.

    I love them so much that they’ve also become my go-to gift for friends and family. Everyone I’ve given them to has fallen in love with them as well. Truly the perfect balance of comfort, style, and practicality.

    Super soft

    is super soft and the most comfortable.. I wore the pants outside for a coffee run... have to deduct one star because the fabric stains easily and hard to wash out stains
