I have a Men's GoLite Ether jacket for sale.Its a Mens size Large.Arm pit to arm pit measurement is 24 inches.
This jacket has never been worn,it's to small for me.I paid $87 for it,and Ill let it go for $60 shipped.

The GoLite Men’s Ether Jacket weighs only 4.1oz and stuffs into it’s own internal pouch. Basically, you can bring it on any trip and not even notice. You sure will appreciate this thin DWR-coated jacket when the wind picks up and light rain starts falling. GoLite even used anti-static fabrics to keep this jacket from clinging to your base layers.
