    Sock material: is M90 worth it?

    Planning on getting a sock. I don't *plan* on going below 0* and figure if it's windy or snowing , I'll be using my MacCat Deluxe with 2QZQ doors to block the wind/snow/rain. Is Momentum 90 worth it or should I stick with 1.0 30d Ripstop?

    I made a top cover to go with a UQP out of M 90 MR,,its ripstop nylon,,the M 90 T is tafetta and rips easier, and is holding up very well..way light,,and breathable. If you make one,,keep the shiny side out which is more water resistant, and less prone to condensation. Its alittle more expensive than your other materials.

    i'd stay away from anything that is calendared...which reduces the breathability of the fabric/sock

    I've made socks out of Pertex Microlight (which I believe is very similar to M90) and also out of 1.1 oz. ripstop. The Microlight does a better job of passing water vapor to the outside of the fabric, and I expect the M90 would, too.

    Acer, most of the humidity that a sock has to deal with comes from the occupant, not from outside. You need the shiny side on the inside. The rougher outer surface has more surface area and lets water evaporate faster.

    interesting stuff WV, my question would be about socks in general, seeing as i sleep like a radiator, so i generally dont worry about using a sock. Also, i was worried about condensation, b/c i have slept many times in winter conditions in a hammock. i thought when hammock socks came out they would fail hard... apparently not. if you take your gear out for more than a night or two in winter conditions, you are looking at more water than you ever thought possible, if only there was a way to put that in your water bottle in the winter............

    keep in mind there's lots of different kinds of 1.1, that's a very generic term that speaks of the weight of the fabric and nothing more. it can be finished a variety of different ways. most of the 1.1 avail to the diy community is calendared on both sides making it the least breathable variety of 1.1

    I have a sock made out of M90 and it works dang good. I think condensation can be a problem with any material if the conditions are prone to it. That being said, its very wind resistant and makes a huge difference keeping that cold wind off of you.

    Good point. I used ripstop seconds from DIYgearsupply. To my unprofessional eye, one side of the fabric is slightly shinier than the other, but not much. It's nothing like the difference in the two surfaces of Pertex Microlight or of Momentum 90. The ripstop sock doesn't block breezes quite as well as the Pertex, but it still makes a decent sock, IMO. Similarly, it doesn't pass humidity to the outside quite as well, but it's still serviceable in that regard, making it a fine material for a budget hammock sock.

    Warbonnetguy, I've read that the difference in the two surfaces of Pertex and Momentum are products of a special weaving techniques, but I'm not sure whether calendaring is what is meant by that. I thought calendaring was a post-weave process that made the surface shiny. Can you shed any light on that? Just curious.

    Oops,,didn't know,,will have to do some modifying then, Thanks for the suggestion.

    I stand corrected,,,I have the shiny side on the inside,,and the rougher surface on the outside. So when I checked it out, didn't need to modify anything. But thanks WV for for correcting my mistake in posting.
