Inner tent has a built in groundsheet, so no creepy crawlies + useful organiser pockets. Outer tent is super strong and has multiple guy ropes to keep it clear of the inner one so never leaks. Full assembly instructions included in these photos.
Best done with two people as it really is a lovely big tent! 5-berth, steel-poled tunnel-style tent with 3 bedroom pods. Pics from the web as I can't find ours, but our tent is identical, including colour.
