This was posted yesterday in "Reader Reviews." I didn't take time to appreciate when I purchased the tent that most of my hikes are done in temps right around freezing:
My Contrail arrived last fall but opportunity to use it has come only twice. All of the positive comments above regarding the quality of workmanship and ease of pitching are agreed with here. It is a remarkably easy tent to pitch and to quickly break camp with. Examination of the seams and tightness of pitch brings nothing but admiration for the manufacturer.
One concern from the two nights on the trail, one last fall and one this past weekend, is the cold air circulation effect on sleeping comfort. In a fully enclosed tent I can use my 15º bag comfortably down into the low 20s or high teens but in the Contrail this same bag won’t cut it even at barely freezing temps. I have a warmer bag but, of course, it is heavier, and by packing it I have erased most of the weight saving reaped by the light weight Contrail.
In April using an Ettowah Meadows tarp which pitches close to the ground with very little ventilation in temps just below freezing, maybe down into the high 20s, I was warm and had to shed my heavy duty head gear. But, without ventilation, it began to rain inside the tent by 3:00 a.m. The Contrail has produced absolutely no condensation in similar conditions because of the ample ventilation and air circulation
This is a serious issue and will have to be dealt with if I am to continue to use this tent. The solution seems to be a big bucks, SUL bag. I have even discussed this issue with Henry and the possibility of a breathable material and possibly in the future we may see some new designs based on breathable fabric. The Contrail, as well as other Tarptent designs just will not provide the sleeping comfort in temps that I frequently experience in my present set-up.
The 3.5 rating relates totally to this aspect of sleeping comfort and is a reflection of my personal needs only. Forum rules require a rating to post this review so I was forced to rate the tent which I freely confess is based on this personal issue I have. If warmth was not an issue or could otherwise be dealt with, the rating of this tent would be a 5.0.
