Thanks for reaching out to us! I am moving your post to the "Ask an REI Employee" board, where another employee will get back to you shortly.
Hey there @Donaldcbell!
I'm sorry to hear that one of your tent poles broke, I know that can be a frustrating experience! While REI does not carry replacement poles for our tents we do work with Tent Pole Technologies who is able to repair and/or replace tent poles for REI tents. I have worked with them personally and they do top notch work!
In the meantime, if your need is urgent, you should have received a tent pole repair sleeve with your tent. You can use that to make your pole functional in the short term until you are able to get it repaired. This Expert Advice article can help you with that.
I hope this helps get you back out camping as quickly as possible, thanks!
