I whine about this every year, and to be fair it has improved, especially in the women's hunting gear area. However, it still has a long way to go. Most of the time women's winter clothes are half as thick and twice the price as men's winter clothes. Men also have a ton more options. When I go to the Cabela's website and click on long sleeve shirts for men I get 3 options; light, medium and heavy weights. On the same site I click on the long sleeve shirt for women, and that's the only option I have. In the men's section there is also a tab for flannel and chamois shirts.
Even in Tractor Supply today there were 2 racks of long sleeved shirts for women, one with really thin shirts, one with some slightly thicker shirts. There were about 6 for men and they were all thicker with the exception of the sale rack from their summer shirts.
Lets look at some examples.
This chamois shirt is a light weight cotton for $39.99
For the same money you can get a medium weight men's chamois shirt
For another $5 you can get the men's heavy weight version.
Here is a better example of the money doesn't equal fabric equation.
Women's version $79.99 Flannel with Sherpa lining
Men's version $50.00 (granted this one might be a close out)
I should probably also mention that I hate clothes shopping, and in general find women's clothing to be outrageously priced. Marshals is probably my favorite year round store, but there is no way I am going to find real cold weather gear in Marshals. So guys, this may be one of the reason that your girl is freezing while you stay toasty.
Normally this would just lead me to wear men's clothing all winter long, but now that I am a supervisor I am supposed to look professional, not like a grunge kid from a bad Seattle band. So this year will be particularly challenging. My goal is to stay warm, not go broke and look like some type of professional. As always, I am always open for suggestions.
