i demo'd the "rocket tent" which is the exact same tent but made with cuben fabric. I'm assuming this tent offers more ventilation than the cuben one I used which was a drippy sweaty mess.
There are a few problems with the tent design. My big complaint is there is no netting in the enterance. If you want to door open to vent you're leaving yourself open to bug attack (even for skiing this can be an issue in the spring), and if it's snowing mesh can stop the flakes from getting in. You can add your own if you're crafty, but still, i think it's a fatal flaw.
The other problems are if you're using your poles/probe, you need to dissamble the tent to tour. Not an issue if you are on the move. Also, it requires several point to be staked out, further eatting into your kit for the day, or requiring a perfect spot on turf, or other anhors in snow.
I think the firstlight is worth an extra pound in winter for set-up ease and room (an odd statement), and for summer I have never fouund anything to beat the Betalight tarp in terms of weight or room, and it's great in winter for a one night stay (or more with a groundcloth).
