>>449965You're going to want something 0-10 if you're not using a pad under you. The first time I hammock camped I froze because I didn't bring a sleeping pad to insulate my back.
>>449967I have the Viggo 40 and 20.
The 20 is absolutely enormous, but it's pretty warm. I'd say I would be comfortable down to about 35 in it.
I don't see the T15 on their website, is it being discontinued?
