@dahliagirl56 Thanks for reaching out!
That is the Sierra Designs Tuolumne Insulated Jacket, and unfortunately it is no longer available from REI. If you'd like to see the product specs you can clink on the link above and see it in a different color. You can also check it out, in the color you have above, here. It appears that it was probably a past year's model and has been sold out for some time. Currently, Sierra Designs has a lighter option available on its website called the Sierra Designs Tuolumne Sweater. It is likely that the version you were looking at is a heavier jacket that typically become available in the fall/winter.
Hopefully this helps!
