UPDATE!!
The tack shop I purchased the girth from, M&M Tack in Raleigh, NC, talked with Fairfax recently. They said that in NC, 7 years is a healthy lifespan for a leather girth due to our climate and regular exposure to sweat (I’m a bit skeptical, as I’ve lived in climates from southern NM to Houston (10x worse than NC) and haven’t seen cracks like this in anyone’s girth, but I digress). However, the owner and Fairfax offered to sell me one at what what I suspect is likely cost to produce (a fraction of the retail cost). I mentioned picking it up on Saturday, and the owner told me that the store was closed for the fourth of July (I forgot it was Sat) but she’d meet me there anyway to sell me the girth. How incredibly accommodating!!! I of course said no, and I’ll pick it up on Thursday. I asked her to please re-inform me on what is considered good care for this girth (I have been following that closely, I thought, but apparently was wrong) and asked if I should purchase a sheepskin cover (Lemieux makes ones that fit Fairfax girths) to extend the life (it was mentioned upthread). She graciously offered to meet me at the store to discuss. THAT is customer service.
I am very happy that the store and the company stood behind their product/products they sell. While I’d be hesitant to buy another new, maybe I got a “lemon”. I’ll find out. My horse goes in a 28 narrow, and I couldn’t find similar dimensions in other anatomical girths. He really likes this girth and I’d really rather not change things with this horse because he’s clear when he objects to tack or things that change. He’s going quite well right now, I’d rather not go through the whole girth thing again. I suspect this is a high-maintenance girth…I can do that to extend the life.
Again, huge shout out to M&M Tack for really trying to help me and standing by what they sell. And, a huge shout-out to Fairfax who also stands by their products and worked with the store owner and me. They could have been jerks about it - they weren’t at all.
