ECB gave you better info for the Convert than I can give you for the Jannu. I do have a couple of Hilleberg tents and have set up and been in nearly all of them, Jannu included. It is definitely more cold weather oriented compared to many 4-season tents...built stout, but doesn't have the ventilation options of the Nallo's, Allak, or BA String Ridge for example. It is put together pretty tightly (read: temp. boost). For what it's worth, Hilleberg's have consistently been the best made (attention to detail, quality, etc.) double wall tents that I've ever seen. Up to you to decide what fits your needs, but I decided the Jannu was more cold weather inclined than I need. Good luck!
