I bought these panties because I needed something to wear under a sacroiliac belt. Regular panties with a sacro belt caused me great discomfort due to the elastic on the legs digging in. I've purchased Calida nightwear in the past and knew it was good quality so when I saw these I thought they were worth a try. I'm happy I did. These are cool and comfortable, lightweight and very well made. The legs don't ride up with wear and the gusset is wide and comfortable. Even now that I no longer need the sacro belt I'm still wearing these- that's how comfy they are! They are not a slimming panty, that is- they are not a heavy weight elastic material. These are a lovely soft cotton. They do seem to run a bit large so be sure to check the sizing guide. I would normally choose a medium in most products sized to fit S/M/L/XL but in these I take a small.
I do wash by hand and hang to dry even though machine washing is allowed- I think it makes them last longer.
