Billy Posted February 6, 2003 Posted February 6, 2003 Does anyone know who makes the lightest bivy sack these days? Thanks for any info Quote
gregm Posted February 6, 2003 Posted February 6, 2003 check with MEC. a friend had a very basic one made by them he said was the lightest out there. Quote
North_by_Northwest Posted February 6, 2003 Posted February 6, 2003 Depends on what you're willing to settle for. There are some super light ones out there, but how long will they last and how much protection will they really give you? I bought the standard OR model. It gives great protection and weighs 1lb and a few ounces. It's not the best, but I find it's pretty much bombproof and very light at the same time. It's a good compromise in my opinion. Quote
Skisports Posted February 6, 2003 Posted February 6, 2003 It is almost bomb proof but any marmont that comes near my bivy bag will get a rock in logded in its head when I was up doing forbidin a few years back a marmont ate the straps on my helmet and through my bivy bag. BTW check interagal designs Dave Quote
Dru Posted February 6, 2003 Posted February 6, 2003 marmont? interagal? Back to the shuttle, Spock! We've landed on the long lost Planet Of Muffy Spellers! Quote
rbw1966 Posted February 6, 2003 Posted February 6, 2003 Bibler Winter Bivvy. At a scant 9 oz's its sure to be a hit. Compresses small enough to fit in a pocket. winter bivvy Quote
JoshK Posted February 6, 2003 Posted February 6, 2003 marmont? interagal? Back to the shuttle, Spock! We've landed on the long lost Planet Of Muffy Spellers! LOL. dont worry dru, I have it on good authority that skisports had tipped a few back when this was typed up (1:36am...cough cough ) Quote
jordop Posted February 7, 2003 Posted February 7, 2003 Serratus makes a superlightweight job, marketed as a VBL, but made out of semibreathable nylon. MEC had only a couple and I picked up the last LONG size. Not on the mec or Serratus sites, but keep an eye out for it if you want a cool emerg bivy. $60 CDN kinda steep though. Quote
Attitude Posted February 7, 2003 Posted February 7, 2003 Serratus makes a superlightweight job, marketed as a VBL, but made out of semibreathable nylon. Ummm.... This doesn't make any sense. A Vapor Barrier Liner should not be breathable. What's up with that? Quote
jordop Posted February 7, 2003 Posted February 7, 2003 Depends what you consider a VBL. Twight calls a microfibre windshirt worn over polypro a VBL layer as it inhibits some moisture but not all. Having once tried to bivy in a coated VBL once in Idaho and waking up in a peculiar cold sauna, I think that a semipermeable nylon job would be a good compromise. Quote
Attitude Posted February 7, 2003 Posted February 7, 2003 Depends what you consider a VBL. Twight calls a microfibre windshirt worn over polypro a VBL layer as it inhibits some moisture but not all. Well, Twight says fun isn't necessarily fun. A vapor barrier liner should be a liner that is a barrier to vapor. Barrier as in impermeable. The point of the barrier is to keep the outer insulation dry from sweat. Polypro? Yuck. Wool Rocks! Quote
freeclimb9 Posted February 7, 2003 Posted February 7, 2003 from warmlite.com: "Gore defined “breathable” as passing water vapor about 1/20th as fast as uncoated fabric, (the same as most urethane coatings)". The bivy bag I have works as a VBL, though not as bad as a polyethylene bag (i.e. Hefty-esque). What do you want for your money? BTW, with regard to "Barrier as in impermeable", a net is a barrier also. Quote
Attitude Posted February 7, 2003 Posted February 7, 2003 barrier - n. a thing that prevents passage or approach. (Webster's New World Dictionary). So a vapor barrier prevents passage of vapor. Like the garbage bag (hefty-esque). I understand the concepts. I'm personally a big fan of windshirts over baselayers for travel in most conditions. But the windshirt isn't a barrier to vapor transport. It does slow down transport, but it is not a barrier. Quote
Pencil_Pusher Posted February 7, 2003 Posted February 7, 2003 REI sells the Tahoma Mountain Rescue Emergency bivy for ~$4.25. It even comes with a pack of matches and some survival tips on paper! Shirley it's the lightest on the market. Quote
freeclimb9 Posted February 8, 2003 Posted February 8, 2003 Warmlite is full of shit. Their mantra of "anybody who doesn't use what we use is stupid". . . My $.02. Yea, the old crank had some cra cra ideas. But the old Stephenson Tent catalog centerfolds were spank-worthy. Quote
Kevin_Ristau Posted February 8, 2003 Posted February 8, 2003 The Outdoor Research Wintersack is made of Dryloft and weighs 13 oz. The Integral Designs saxk is made of Pertex microfibre and weighs 11 oz. The dryloft bag would be more weatherproof, but a microfibre bag breathes better. The warmlite website is somewhat fanatical, but their sleeping bag models are worth a second look. Quote

Pro Mountain Sports Posted March 15, 2003 Posted March 15, 2003 The Integral Designs Endurance Bag Cover is made from Pertex Endurance waterproof/breathable fabric. The seams are even taped. Quote

JoshK Posted April 3, 2003 Posted April 3, 2003 For anybody who hasn't seen the MEC lightweight Bivy, it's pretty sweet. http://www.mec.ca/Products/product_detail.jsp?PRODUCT<>prd_id=118583&FOLDER<>folder_id=590703&bmUID=1049349972721 As far as I can tell, integral designs makes it for them. It's basically a totally stripped ID bivy. It's made out of their nice waterproof/breathable fabric (same stuff as ID and bibler tents), but lacks zippers, bug netting, etc. at only 1 pound, I think it's a great comprimise between the glorified garbage bags and the full on bivies.
