> I think fleece provides very little warmth. Richard said about 1 clo for 100 wt. I don't think heavier fleece provides that much more.
I dunno; a CLO of 1 is pretty respectable, equivalent to a wool suit. But I'm pretty sure Richard meant Iclo of a little under 1 for 100 wt fleece, which has to be multiplied by garment coverage. According to notes I've taken:
- “Average” Polartec 100 weight shirt CLO = .40
- “Average” Polartec 200 wt shirt CLO = .76
- “Average” Polartec 300 wt shirt CLO = 1.03
Remember you have to add the above CLO to whatever else you're wearing to get an overall CLO to look up on Richard's chart. I doubt few of us are wearing a fleece shirt and naked everywhere else (except Paul, maybe).
> So per the handy chart, if there are 3 uniform weights to non-waterproof fleece, then my zip pullovers are 100's, my Lands End vests are probably 200s, my unlined sweater-jackets are 300s. OK.
I also wondered what oz weights applied to the various polartec weights for shirts/sweaters, and here are my notes:
- 100 wt tops range 6-11 oz.
- 200 wt tops range 13-20 oz.
- 300 wt tops, I don't know; I've seen one number at 32 oz.
> I would really like to try polypropylene fleece...Anyways, i will stop derailing Delmar's thread here. If anyone is ever interested in doing a group buy of some of that PP fleece, let me know.
Me too! and Please continue! I don't sew (yet) so I wouldn't know what to do with a bolt of PP fleece, but I'd stand in line to buy a sweater of it. Generally the base layer soaks up most of the odor, so I don't imagine having a PP insulating layer would be so bad.
Start a thread on it in the MYOG Justin, and I'll bet you get your buyers in no time.
