We will be in egypt from Late march to late April. We are coming from Canada. It is around -15c right now.
The lady bought some expensive marina wool shirts, under the impression that it's property of "self regulating" the temperature would make it good for hot days and cooler nights.
I am under the impression that the qualities of marina wool are effective in cooler climates when you need to shed body heat, not avoid external heat sources.
Anyone with some experience that could shed some light on the situation? or perhaps make a recommendation about the effectiveness of wool in Egypt?
First off, it's "merino." And it does keep you more comfortable over a wider range of temps than any other single fabric. As for whether or not it'll keep the lady cool in the heat, and warm when it's cool, it completely depends on the temp range you'll be in and the density of the wool she has. I have a lot of merino wool clothing and often take it with me travelling. I take the thinnest stuff when I'm going somewhere hot and I'm at least as cool as when I'm wearing a very thin cotton shirt. It'll also keep me warmer if it does start to get cool but you do need to be sensible and layer with other garments as the temp drops.
Merino helps keep you cooler because it very effectively moves your sweat away from your skin and out thru the fabric. Best of all, it doesn't stink when you've been wearing it for a while so you don't need to wash it as often. It wrinkles very easily though so you have to be careful packing it if you want to pull it out of your pack and look presentable.
Thank you Aaron. I appreciate the info. She will be glad to hear it.
Merino does make more sense, as there is nothing particularly nautical about it.
Merino is a sheep breed, teh finest fleeces of which come from Australia.
