"Its one thing to pare out weight to achieve a world record for the lightest two-skin tent commercially available, but it can potentially conflict with functionality....... The same philosophy applies to the lack of even a minimal mesh storage pocket inside and a storm flap over the zipper, which would add another ounce. And while we're at it, how about adding a high vent or two to lessen the condensation problem?"
I don't understand this remark Will. This whole site is dedicated to saving every gram you can squeeze out of your pack, even up to the point of madness (I remember a forum post of a guy proposing to use a snorkel to get rid of bivi condensation) and now there's a mainstream manufacturer going the length to create a truly lightweight double wall tent, cutting every gram that isn't absolutely necessary and now you want details that add weight. I mean do you really need a mesh pocket? When you go tarp/biving, does your tarp/bivi have a mesh pocket or can you live without it while you tarp/bivi? I can! And what about ventilation, yes indeed it's nice, but do you truly need it when every gram counts? Wouldn't you compromise for condensation in favor of saving a few grams?
If we are talking about normal camping, i.e. taking a normal lightweight set of gear, I agree you would want ventilation in your tent. And if you want ventilation take a look at TN's Laser model (altho I just saw it has an extra door this year, booooh!). Very ingenious ventilation on either end of the tent which can be operated from the inside. Yes indeed it's almost a pound heavier, but that's the price you pay for adding features. In your review you compare the Photon to the Akto, which is almost a full kilo heavier than the Photon. Wouldn't you agree that a fully featured Laser is a much better comparison to a fully featured Akto than the Photon is?
So my two cents to add to this review is a bravo for TN to make a double wall tent that is truly lightweight AND easily available through your local retailer (at least in Europe).
