darstog Posted March 16, 2005 Share Posted March 16, 2005 Which is more breathable (for similar face fabric)? Does anybody know of any quantifiable data for this? And GE just bought eVent, so will paclite go away? What it boils down to is this: WT Bivy vs MH Bivy Quote Link to comment Share on other sites More sharing options...
marylou Posted March 16, 2005 Share Posted March 16, 2005 Personally, I think eVent is a more breathable fabric. Â Much more, matter of fact. Quote Link to comment Share on other sites More sharing options...
darstog Posted March 16, 2005 Author Share Posted March 16, 2005 ...and... if the eVENT is more breathable, do I need that sort of breathability? I'm not doing aerobics in my bivy. Is the PacLite breathable enough? Esp. for the weight savings. Quote Link to comment Share on other sites More sharing options...

RideT61 Posted March 16, 2005 Share Posted March 16, 2005 I work in R&D and test waterproof breathable fabrics. I can tell you that eVent is significanlty more breathable that any other "hardshell" fabric on the market. I can't give you values that would mean too much because there are several standardized industry tests for measuring breathability. Most companies (fabric mills) use the test that makes their product look the best. I can tell you that eVent comes up a winner in every test method I have seen, the only thing that varies is how much better it performs. I coulg go on, but it gets a little technical and boring for most people. Suffice it to say that eVent is the shit. Quote Link to comment Share on other sites More sharing options...
Ade Posted March 16, 2005 Share Posted March 16, 2005 The best thing you can do is not stick your head inside the bag if at all possible. This massively increases the amount of moisture the bag has to transmit through it's fabric. Â Also remember that in sub freezing temps breathability is significantly decreased by icing on the inside of the bag. This will happen with all fabrics. If it's going to be freezing I don't even both with a bivvi bag, I take an insulated overbag instead. Â Strikes me both these bags are heavy. I have a Rab Survival Zone that comes in quite a bit lighter than of either of the above. Â The fabric is only part of the story. Good fabric isn't going to make up for poor design (just ask OR).

jorvack Posted March 16, 2005 Share Posted March 16, 2005 Actually I think epic makes the most sense. It breathes and sheds light rain and snow. Bibler used to make a winter bivy. Its 9oz. my 2 cents Quote Link to comment Share on other sites More sharing options...
darstog Posted March 17, 2005 Author Share Posted March 17, 2005 Say what you want about Jorvack's madness, but his methods have some validity... However I'm most interested in a bivy that will be truly waterproof... going to bugaboos, tuolumne, NCascades, etc for a couple of spring/summer/fall days, want to to stay really light, may have to deal with afternoon showers. I'll carry an extra 7 ounces (MH Bivy) or an extra 11 ounces (WT) to for full waterproofness and some weather protection. The idea of an overbag sounds great for colder temps, and the bibler looks great for snow stuff, but 3-season superlight waterproof coffin sounds like it would be a great addition to the closet of gear that's really only used to sleep out next to the river at Index.

Rafael_H Posted March 18, 2005 Share Posted March 18, 2005 I saw an eVent bivy bag (1) at Marmot today - 3/17/05. Made by ID, I think. Quote Link to comment Share on other sites More sharing options...
