Waterproof ratings

post #1 of 7
Thread Starter 
I'm looking at a Bonfire jacket that has a rating of 3000mm. What does that mean and is it going to be waterproof in heavy wet snow?

Just for comparison, a sponge has a rating of about 2500mm. Seriously, if you need to stay dry for very long in wet snow, look for 20000mm.

I'm sure there are better articles/explanations around, but this one http://www.backcountry.com/store/new...1Cc&mv_pc=r105 just came up on the new Backcountry.com newsletter. Might get you started in the right direction.

However, something to consider is the higher you go in waterproofing, the less breathability you get from the fabric. For me this has always been a tricky balance. If you perspire much, waterproofing can be a nightmare in some jackets. I thought I was being smart buying a high rated waterproof jacket a few years back, however, the jacket did not breathe, and in turn, it would just hold persperation in (making you wet and cold).

Remember, nothing except rubbber is completely waterproof. Look for something with Conduit, HyVent, or GoreTex.

I find if you keep the DWR fresh, they're all good. (camping/BC excluded) I have an 8y.o. goretex marmot 3L that has held up if I keep the DWR fresh. My new conduit also needed a recoating last year. Hyvent also needed it after a season. I don't demand goretex anymore. it all seems pretty consistant if the jacket is well-coated. I think goretex is just the toughest and usually lasts the longest. But now I prefer bargain shells that can easily be replaced next season. who wants an 8y.o. jacket?
