Urgent – is my favorite piece of fly gear ever gone forever? Alternative recommendations?

I purchased one of these from the Gallatin River outfitters proshop and it is hands down the favorite thing I own, wear nonstop on and off the water in summer and hoping to find a second or third one to stock up on because it appears to be discontinued. I emailed simms and they said they thought it was coming back for this summer but never did… lots of sun hoodie options I know but the rear zip pocket is just too clutch when im out stalking through creeks and im having trouble finding another sunshade weight hoodie that has one … anyone know if these (beyond the couple of stores with leftover XXL’s) or if they are available somewhere or if another brand makes something similar. Thanks so much!!!

Sincerely grateful for any help
