The Uni Spider Mozzie Mesh Front Door is a full mozzie mesh front panel. This front panel is designed specifically for the SP Uni Spider and South Westerly Pro Uni Spider bivvies. The front panel features a self-closing Snap-Loc magnetic system. Every time you pass through the front panel, it closes automatically due to the magnets, preventing insects from entering your tent. The front panel is easy to attach through the Easy-Flo zippers.
