Change in material
I've dropped a good chunk of change on Bonobos clothes and consider myself fairly Bonobos savvy. I own three pairs of travel denim, all of which I purchased last year (and would own several more pairs if Bonobos hadn't run out of my size, 32/36; I love those jeans). I was excited when Bonobos released new travel denim in my size, but was disappointed to see that the denim-manufacturer had changed (to Cone denim, apparently) since I was last able to buy travel denim. These new jeans are well tailored, meaning they fit nice and are flattering. But the jean material is very different than last year's travel denim; it is heavy, not light/cottony, and it is more consistent with the feel of a heavy burlap sack than the light/airy travel denim of yesteryear. The result is that these look good, but they don't feel comfortable/relaxing, which was always a big selling point of these pants. I'll probably keep them since I don't have much in the way of options at my jean size, but I was very disappointed.
A durable solution to the original travel jean
by Vick Vinegar
I will start by saying that if you are used to the old line of travel jeans, you are in a for a bit of a surprise when you try the new ones. The older travel jeans are definitely more lightweight and seem to have more spandex in them than these do.
However, I personally like the new Travel Jeans, which seem more durable and the rise is just a tad bit lower; just generous enough. Although the material is thicker than the original travel jean, I still manage to stay fairly cool in these and the bit of spandex is perfect. I would say they have the durability of a classic blue jean without the typical motion limitations.
I own the original Sage Green travel jeans in straight leg (which have started to fall apart the the pocket stitching), and I ordered these in slim fit which actually fits much more closely to the straight leg fit of the green ones. Overall I would recommend buying these, and definitely size down one size in the waist.
I think you will find the durability of the thicker material to be a welcomed surprise, give em' a chance.
