For sale a now surprisingly scarce Therma-A-Rest (thermarest) self-inflating pillow, which probably dates to the early 2000's. I HAVE ALREADY SOLD 1 ON EBAY AND THIS IS MY FINAL ONE! A clever valve on the end is simply screwed in to stop air escaping once opened to let air in. Additional Incredibly light weight and designed to be rolled. Measures approximately 32cm x 42cm. American camping design - made in Ireland and still incredibly functional.
