    How much colder with two pads?

    Does anyone have any idea how much colder one can go if one uses two of the open cell foam pads with the SS undercover? That is, if one can go to 30*F with one pad and a SB, what temp with two pads, and a SB?

    Thanks in advance..John

    into the 20's with a Multimat

    I don't have any direct experience with using two OCF pads, but my work with augmenting the OCF pad with an Exped Multimat is available in my BGT report here:

    With a space blanket you might be able to get into the 20's if using a good mummy sleeping bag. If you are using a quilt on top you won't be able to go quite as low.

    You can go much colder than 30f This hammock has been tested in -18 C, and you could go colder with a decent mummy bag around -15c or -20C 30f isn't even cold...haha!

    Question Have I got this right?

    Thanks for all your responses. I was wondering if it would be better to get two ocf pads from Hennesy. It seems that the heat sheet, and exped multimat, along with the torso and kidney pads would be the best bet, before needing to add further layers. Have I got a handle on this?

    I have gotten to at least 11 with a 3/4 length blue CCF pad doubled with a truckers (silver) windscreen.
    When you have a backpack on, no matter where you are, you’re home.
