Pros: super comfy fabric, good colour, flattering cut, compressive but not overly so. Cons: Not squat proof, water marks don't dry uniform. Went with 5 over 4 star as I purchased them more for casual wear at home and light home exercise and no-one will be around to witness my underwear patterns.
I seek out comfy fabrics for all of my clothing, especially leggings. I've steered clear of the Q-NOVA fabric, as it didn't sound soft enough for me, but jumped at these when I saw bamboo! The berry is really pretty, a fraction more muted than the first few photos, but still a really nice colour.
I got these in XS. I'm a 8-10 UK in bottoms depending on how booty-friendly a design is. These are stretchy, compressive - don't be scared when you pull them out of the package and they look kid-sized! I think I'd have fit into a size S too. These are not squat proof, however the description does say "intended for lounging". I'm not hugely bothered and would adjust underwear depending on where I was gonna be.
I didn't prewash them, so this could be the reason: I spilled some water on my knee and the water spot didn't lighten in colour when it dried, it looked a little bit like a dark stain. I've had this issue before with some fabrics, its rare, but you have to wash and dry the whole garment if you want a uniform colour.
