There are regular threads for bike bags but I've not seen any for bags to contain tent, panniers and their contents. We had lightweight bags by HiGear, bought from Go Outdoors but they started tearing after about six foreign holidays, they've been discontinued and I've found nothing equivalent. In desperation I bought a Logic3 bag from ebay, not yet used but it's smaller and heavier. Our routine was to take bikes in CTC/Wiggle bags, luggage in the HiGear bag and both would fold down sufficiently to take with us so we could return from a different airport. I'd be interested to hear of other people's experience. Photos of both bags attached.
