I own two SWK heavyweights (one Black Watch and one Black Stewart). They are both solid off-the-rack kilts. They are comfortable and I enjoy wearing them. I have no complaints about either of them and would recommend them. SWKs shipping times are also something of a legend here. If you order one today and it's in stock, it will have arrived yesterday.

Only one note of caution: I fall into the particular body type SWKs are designed to fit as fluter mentioned earlier in the thread. If you don't fall into that category, your mileage may vary.
