I purchased the MSR Hubba Hubba 2 to use as a one-man tent and cut down on the weight I was carrying in my backpack. Initially the tent feels flimsy, but that was because I was used to carrying a much heavier tent around. Once you get it set up it's bomb proof.
Features I like are the venting at the very top of the inner tent, entrances on both sides, rain gutters above zippers and the way the zippers on the entrances open right up. The overall weight is also very good for a single person carry.
There is plenty of room inside and I can sit up comfortably at 190cm.
The only thing extra I have done is upgraded the pegs provided to the MSR Ground Hog stakes.
As always The PAST Outdoors team were great to work with and shipped quickly.
