Totally agree about stewing in your own juices is not appealing.Martin Ryehttps://www.blogger.com/profile/03719332121719827761noreply@blogger.comtag:blogger.com,1999:blog-4399206197069094470.post-78058386607675218342011-04-14T21:28:48.993+02:002011-04-14T21:28:48.993+02:00Yeti - if I was sleeping in -30C conditions often ...Yeti - if I was sleeping in -30C conditions often I would use a warmer down bag, something like the WM Lynx. WM also do a good range of bags with wider girths that might suit you. Being able to add your clothes to your sleep system is a great way of saving weight.<br /><br />Dave - Andy knows his stuff! Vapour barrier technologies have their followers, Skurka being the most famous I guess. It doesn't appeal to me, I'll stick with a system that's proven it's worth to me.<br /><br />Fraser - it's a relatively cheap way to acquire a winter set-up. The only downside is the lack of synthetic quilts to choose from.<br /><br />Heber - no, the synthetic goes on top where it protects your down quilt and where the moisture can collect from the inside (the dew-point seeming to be inside the outermost layer). I've seen no evidence of my synthetic quilt compressing my down bag.<br /><br />David - that'll be an awesome combination and ready for any season!Joe Newtonhttps://www.blogger.com/profile/00907231785281446095noreply@blogger.comtag:blogger.com,1999:blog-4399206197069094470.post-3045354832120561042011-04-14T07:51:20.688+02:002011-04-14T07:51:20.688+02:00Joe, I realize now that I thought about the system...Joe, I realize now that I thought about the system from my perspective only. Because of my size I can't wear any extra clothes in the sleeping bag, except for maybe pants. If you can wear those extra clothes in the sleeping bag, it makes sense again and should work when it gets really cold.Yetihttps://www.blogger.com/profile/09021085744187280571noreply@blogger.comtag:blogger.com,1999:blog-4399206197069094470.post-51320389689433951572011-04-13T23:56:17.167+02:002011-04-13T23:56:17.167+02:00yeah man, I got one coming from Ron for the summer...yeah man, I got one coming from Ron for the summer. More money in the short term but half the weight of the go lite adrenaline 3 season (too hot for me in the summer anyway) and means total versatility the rest of the year. Also safety in case down coat or bag get wet - makes perfect sense.selfpoweredhttps://www.blogger.com/profile/10690224905896399570noreply@blogger.comtag:blogger.com,1999:blog-4399206197069094470.post-25170386365100035552011-04-13T23:22:10.466+02:002011-04-13T23:22:10.466+02:00Good post!

I've wondered whether the down shouldn't be on top. Would the weight of the synthetic bag compress the down bag? Did you find any evidence of that?Heberfarnsworthhttps://www.blogger.com/profile/00410284354232381519noreply@blogger.comtag:blogger.com,1999:blog-4399206197069094470.post-59581791844671659772011-04-13T22:00:10.258+02:002011-04-13T22:00:10.258+02:00Interesting, I've been talking for a while abo...Interesting, I've been talking for a while about getting a quilt to supplement my 3 season bag in winter, but hadn't considered synthetic - I don't know why, it makes a lot of sense.

I'm now very keen on replacing my big down bag with something that works. Vapour barrier of synthetic out bag thats the question.

I do wonder, though, if a 879 g down bag and a 556 g quilt really is enough when it gets cold. My down bag (Marmot Never Summer size long) weighs 1900 g and gets cold already at -25°C. Of course if you put a down jacket on top of it you gain a little warmth and that way I've been comfortable at -28°C.Yetihttps://www.blogger.com/profile/09021085744187280571noreply@blogger.comtag:blogger.com,1999:blog-4399206197069094470.post-66502902125000211902011-04-13T20:33:06.467+02:002011-04-13T20:33:06.467+02:00Roger - Thanks!

After the first day I learned to pack my quilt quite near the top of my pack (under my insulated jacket, pants and cooking gear) making it easily accessible at lunchtime.<br /><br />The insulated pants were Patagonia Micro Puff Specials. I've amended the post to include the clothing as it's an essential part of my sleep system in all seasons.<br /><br />Helen - thank you for your kind words. I thought I was rambling a bit but if it's helped explain some of the finer details of why we did what we did then that's all good. Jorgen deserves a lot of the credit for putting the system through it's paces last year. The modularity is appealing, especially if people are restrained either financially from buying a balls-out winter monster bag or even if they just want to own less stuff.Joe Newtonhttps://www.blogger.com/profile/00907231785281446095noreply@blogger.comtag:blogger.com,1999:blog-4399206197069094470.post-55842437298734409532011-04-13T20:15:40.262+02:002011-04-13T20:15:40.262+02:00I have to echo Roger here.

The picture of you sitting the quilt at lunchtime, explains the importance of such a system in winter. That is the synthetic quilt becomes part of you day time warmth system and supplements your night time system.<br /><br />I may have missed this but what insulated pants do you use?<br /><br />Thanks again for the educative post on surviving in winter in harsh conditions.Nielsen Brownhttps://www.blogger.com/profile/16493125853192182579noreply@blogger.com
