I have enjoyed my MSR Hubba Hubba for hiking with my daughter. (Not UL, I know, but it's enough space for reasonable weight, and it keeps her happy!)
It's the original model, with just one door. One problem: the fly has become stickier & stickier over time.
I called MSR to see if they could send me a new fly (even for a price) since they are made differently. They told me this is their fault, & to send them the old tent and then sent me a BRAND NEW one for free!!!! I got it today, and it's noticeably lighter with several other improvements – I really like it.
I have to say this is great service and surpassed my expectations for a 3+ yr old tent!
