Men's Brown Stretch Ripstop Utility Work Pants - Big

Bought these at the beginning of the summer based off the write up here on Boot Barn. I do archaeological field work with a lot of walking and digging a lot of holes so durability was a priority. They definitely checked most of the boxes (rip stop triple stitching breathable enough in hot weather etc). However in the 4 months I've had them in two of my pairs I've already noticed a split from the inseam right along the seam in the fabric itself! Over designed with but compromised in material

I really want to buy more but the site won't let me order and more it saying your all out of 48/30 ?
