Yep, as can be seen by some other threads about being "HOT", it's that time of year ( in MS anyway) when the last thing on my mind is keeping warm in a hammock. Though admittedly, only a little over a week ago on Memorial day weekend, I needed just a little something by about 0300, what with wind and rain and lows possibly in the very high 60s-low70s. I got by just great with my CS Warbonnet torso UQ with one layer. The whole thing weighed a little over 9 oz and was MORE than warm enough. The question is how low will she go, and I suspect maybe somewhere in the 50s. I won't be able to find out for a while, though.
It occurred to me, as the rain and wind blew Mem day weekend, that my SS would have functioned well also. Maybe with just the UC, if condensation would not be too much of a problem due to no heat sheet. So any way, I was playing around with it this morning. Way too hot with the full system, which is what was in my stuff sack. The UC, OCF pad plus kidney/torso pads and heat sheet. First I pulled the kidney/torso pads out. But before I even tried it with out the extra pads, I just pulled it( the entire SS) too the side, compressing it with one strap in the midddle.
That was much better. With temps by now probably about 80 in the shade, no breeze.
So, those who hike certain places, even in the south, might need a little something during cool snaps, especially in the mountains. The WBUQ with one layer of CS is super convenient, as I can vent it or even push it below my butt from within the hammock. The SS can just be pulled aside, though it might still slightly interfere with a breeze. Compressing it down with a couple of straps mostly solves that. But this is either on or off( too the side). I don't know how I would vent it except by putting some clothing down there hoping to cause a large gap.
But, one thing I have never tried is the UC by itself. It might be all that is needed for windy/rainy mid 60s- 70s. Though again, I'm afarid condensation might be a problem.
1st pic, I am pulling it too the side so that it can be seen how this works, though obviously when I let go it will be against the side of the hammock. When you get in, it stays up higher than you are. Use a few straps and you could make it a tight narrow bundle mostly out of the way.
2nd, a view from the foot end with SS to the side.
3rd, SS untied and ready to place HH back inside SS. You can see the upper left edge of UC and just above that, the HH net, just outside the UC.
4th, HH now back inside SS. Notice how well the sides are protected from wind and rain by the sil-nylon UC.
Last two, foot end view of HH inside SS Undercover. Of course, between the UC and the hammock are the OCF pad and Heatsheet, and whatever else ( kidney OCF pad, jackets etc) you might want to put in there. So you can have zero insulation and very little breeze interference by doing this, and still have something handy for if it turns cold and wet. As for in between temps, all I can think of is removing pads or everything removed except Undercover. But then that interferes with the convenience of every thing left connected and in one sack, and condensation may prove to be a problem. But, if a SS is what you have, you can probably be ready for a wide range of conditions.
