I've been attempting to drop weight for the past several years, mostly because my knees can't handle it. My shelters have gotten lighter as have my sleeping system — next in line for a diet was my carry system. Funds, however, were non existent and my CFO (i.e. my wife) wouldn't increase my discretionary fund. We think this is an ideal choice for couples or families looking for a comfortable sleeping system for their next car or RV camping trip. The one downside with integrated rain flies is the lack of ventilation and temperature control. We had great weather – not too hot and not too cold – but it did rain for about 5 minutes. My friend chose to not put up his rain fly betting on the perfect weather to continue while enjoying the stars at night. During those five minutes of rain, he was a little more stressed as the risk of a wet sleeping bag had not been completely mitigated and he rushed back to the campground. True, I wasn’t able to remove the rain fly to watch the stars or let the wind ventilate my tent, but I was able to enjoy the day hikes without any sort of worry.
