Outdoor Research Helium Bivy This item is in excellent condition, having only been test-pitched on the lawn. There are no scratches or stains on the fabric. I checked it inside out and there was no seam lift. You can assume it's in almost new condition, but please be aware that it has been opened and test-pitched, so there may be some unnoticed dirt or other minor imperfections. The actual measured weight, including the stuff sack, was just over 490g.
