@OutdoorMom thanks for reaching out! It doesn't look like we carry this Big Agnes tent any longer at the co-op, so we won't have a specific vestibule for it. One question - are you looking for more exterior space than the current rainfly provides? If so, I have a few ideas: (1) reach out to Big Agnes directly - here's a link to their Customer Support - perhaps they have the vestibule in stock? (2) bring your tent to your local REI store and work with one of our employees to see if anything we currently stock might work - you could set up an outfitting appointment to ensure you'd have some 1-on-1 help! Good luck!

At REI, we believe time outside is fundamental to a life well lived.
