K-way at Cape Union seems to have discontinued the down Tech Kwilt run they made last year. They are 10 degree comfort down quilts, 20D nylon, around 750g with a closed footbox. Actually a decent design mirroring a lot of the lightweight quilts out of the US.
They don’t seem to have sold in our market. So picked the last one up at my local cape union for R480. The staff seemed a bit thrown by that price, so not sure it’s everywhere or was store specific. But thought I would suggest taking a look if there is one near you, as that’s a shockingly good price.
