Just finished reading the article on jean breeches in the Feb. issue of Horse Journal. Very informative - thank you!. I have tried several different brands, including the Tuff Rider breeches. Although I did like the fact that these were a more traditional fit, than some of the low-rise version, I found that the horrible button/hook on the waistband really dug into my stomach when I was riding or seated, even though the waistband was not tight (I got a size larger than I normally wear). I have a round bum, and these jeans, as are most of the Tuff Rider breeches I have tried, are made for a more flat "behind". I replaced the horrid hook with a button and button hole, and still wear them ocassionally.
Last fall I was checking out e-bay, and found a pair of Hac Tac jean breeches. Wonderful!! They are a regular "jean weight", stretchy fabric and are made for a "curvy" figure. Thankfully, I found a second pair a little later. They are made like regular jeans, with front and back pockets, and the unfinished legs allow you to shorten the length as necessary. They are made with matching fabric knee patches, and yellow/orange stitching (no seams on the inside leg). These are so comfortable, with just enough stretch, so they don't get baggy. The only problem: so far, they don't sell them in the US, just the UK. I really wish that some enterprising tack shop would import them - I think they'd be a real hit!
