Never opened, never left the house. Bought for a specific touring trip but ended up deciding to just use partners tent instead of one tent each.
Very cool tent, minimum weight is 1.8kg excluding pegs so perfect for solo winter backpacking use as well as alpine excursions.
Retails at around £450 and has Nemo's Lifetime Warranty.
