Single Person Monolith

While this is a nice piece of equipment there are some flaws in the construction. 1) It needs better corner definition. While setting the monolith up the corners would just wander from their spot and not stay in place. 2) A sleeve is needed to extend out onto the corner piece that attaches to the air valve to better insure a good seal so air does not leak out. 3) More material or a zipper needs to be added at the point of entry and exit so that sealing becomes easier. Also, assembly instructions with picture diagrams would be helpful. After all this being said the monolith is actually a great piece. The group really enjoyed using it.
