@Brpportland Thanks for reaching out!
When are you looking to climb Mt. Hood? It's a real adventure up there, I climbed it several years ago on a bluebird day and by the time we summited the weather had gone from beautiful to miserable (wind and clouds and minimal visibility) and back to beautiful again. When are you planning your climb?
At this time we are not offering rental service at our stores. Because everything is still quite variable and last-minute changes can be very frustrating, your most up-to-date information on current services will be on the REI store pages.
Hope this helps!
