Can anyone recommend a 2 man tent that will fit in the pannier?
Find the tent you want (3 man is much better if you're ever going to have 2 people sleeping in the tent).
Then replace the tent poles (because they'll probably be too long to fit in the pannier) from this place: Linky or someplace like it.
I found that with a quick search.
What I was saying is that with two tents I just looked at the pole length was considerably shorter than the advertised pack length. If I didn't know this I would have ruled out some 2 man backpacking tents that otherwise meet my criteria.Just about any tent (without the poles) will fit in a saddlebag.
The pole-length is the limiting factor and when you look at tent specs - look at the 'packed size' number. An 18x6 packed size typically means the tent pole sections are 18" long.
There are many backpacking tents out which have shorter pole lengths as it makes backpacking easier. It's pretty easy to find 2-person backpacking tents with 15-20" pole lengths. The 3+ person tents are a bit tougher to find smaller length sections but there are a few out there. The alternative is to pack the tent material in a saddlebag and the poles separately but that means there's a possibility you forget the poles and some have done that, not a fun time.
