Winter Sleeping System?

Instead of the Prolite 3 large, I'd consider using a "short" length pad with a smaller sit pad to cushion/insulate your legs. Personally, I use an Exped Downmat 7 short combined with a 10" x 20" blue foam sit pad and my empty pack under my legs. There are lighter options than mine, but it's extremely comfortable and warm. It also weighs right around 28 oz. A lighter option would be a TorsoLight pad with a full-length GG Thinlite underneath.

Ah, I wish I could use the short pads but they are too narrow for my shoulders. I need a pad that is at least 22" wide or my shoulder blades are on the ground. I wish someone made a 24" wide short pad.

Chadn, I agree with you on pad width. I have the same pad as you for that reason. I understand that you have the Prolite 4 and not the Prolite 3, is that correct? In either case I think you will need to combine it with another pad to give you the insulation you will need for winter use. A closed cell pad on top of your Prolite will work the best. Convection currents within an air mattress can still be a problem with the air mattress on top. Gossamer Gear sells wide versions of their pads.

Yes I have a ProLight 4. Thanks for the tip about G.G. I'll have to check them out.

By the way dose anyone have any recommendations on a good set of Vapor Barrier clothing?

Mark Verber has a discussion of Vapor Barrier clothing on his website.

If you haven't already, definitely check out Andrew Skurka's latest bit of insanity…he hiked the SHT and further just a few weeks ago. Two podcasts and member's article on this site (Ultralight in the Icebox) and lots of stuff on his own site (http://www.andrewskurka.com/ICE07/index.php).

I have both the RBH Designs NTS Shirt and Pants. I also use their VB socks. I have a thread here someplace about wearing the RBH VB gear. This is on-going and should last well into spring. It is 42 degrees where I am and I am about to wear them for a 2 mile walk.

Chad, i agree with the closed cell pad, I have an ancient one that I've used for years that has always worked great in winter. Unfortunately I was out in the tetons a few years ago in 40 below and it cracked. Your right on with the bivy too, i have a small one person north face bivy tent..people say butane is bad with cold, but my little butane ultralight stove did fine at 40 below, just warmed the cannister in my bag or in my clothes. Good luck! I'm trying to get someone to go on weekend trips this winter in MInnesota and its hard to find anyone, I live near the cities and am laid off and have time on my hands. Randy

Hi Chad, you should contact Matt Lutz (you'll find him on these forums) as he just attempted a winter thru of the SHT a few weeks ago. I believe deep snow became an issue, but his gear list was well put together and could give you some insight…just a thought.

I haven't found any VB clothing (pants or shirt) that is an exceptable weight ("IMO"), so a VBL for your bag is probably the lightest option for sleeping, unless of course you plan on wearing the VB's during the day in which case you would sleep in them.

P.S. Downmat 7 (Short), GG 1/8" thinlite…killer combo. Bags look good.

Hey Chad, I believe the width of the short Exped downmat 7 is 22". It's listed as 20" on the website, but it's actually 22".

I've been thinking about getting one, but haven't done so yet. Maybe someone who has one already can verify?

I have one. When inflated it is around 20", depends whether you measure sticky out uninflated edges. When deflated it may well stretch out to 22"

My sleep system consisted of the following:

-20 down bag
2x 57" CCF pads (one Ridgerest, one generic blue foamer)
Stephenson VBL clothes

I was also in a tent and used my GG Vapor Trail under my feet. I could supplement the system with any of my clothes – Montbell Thermawrap pants and TNF Nupste jacket. Everything was a system that worked together, both while the gear was in use and when it was packed on my back.

Like Skurka, I took what I had. I thought about using a two bag system (also have a 30 degree down bag), but I trust the -20 down bag to its rated temp and I didn't want to get an overquilt with little time to test the system.

I anticipated temps colder than what you have stated. I expected lows around -30 and highs in the mid 20s. The record low in Grand Marais for the first two weeks of January is -35, and it is colder up on the ridges. Given the weather over the last two weeks, my estimates were on spot. (On another note, my mother called me last Thursday when northern Minnesota was registering temps in the -30s to state that she was happy that I was at home and not hiking).

In the initial thoughts on the trip, I thought about going with a a wp/b bivy with a head hoop – I eventually purchased an OR Alpine Bivy, but later returned it in favor of a shelter I could sit up in – an Integral Designs MK1. Because it snowed 8"-16" the the first night, I was glad that I was in a tent – I could sit up, move around, keep snow out of the shelter easier, etc. If (and when) I do it again, I think I would seriously look at a bivy and floorless shelter setup. My current thoughts is MLD Superlight bivy and DuoMid for a shelter system.

Are you using an overhead shelter? I know you have a DuoMid, and when I initially read this thread I read that into your stated system. Can your bags fully loft inside the bivy with you in it? It is a bummer that you need wider pads – you should be able to get an appropriate pad at http://www.mcmaster.com/ – you can customize length, width and thickness.
