In reply to sammiKrogers:
I think you're asking about two things which cause problems for each other, technical spec and looking good, the former doesn't sell very fast and the latter means you have to stock a large range (because one persons looking good isn't the same as the next). Women's outdoor clothing seems to have a lot more work go into it, not just with shape, extra colours and fitting but with additional stylistic features like patterning or sewn on flowers for example. If a shop is trying to stock technical gear then a mans range is basically a small colour palate that wont change in years and medium to XL are the sizes that really sell. So you don't have to buy much variety in. In womens ranges though you generally get a lot more colour choices, which often change, plus you're more likely to need a 10 or an 18 than you are a Small or a XXL, so you end up having to stock a large amount of stock. Add to that the fact that a) womens technical clothing sells slowly and b) it's very expensive to buy then you get a scenario where the manufacturers are making all this lovely kit but no one can afford to stock it.
I think the manufacturers themselves make some lovely tecnnical clothing for women, a quick look at HH base layers for example and the mens is green, black, navy, the womens have about 8 different colours and loads of patterned garments. The manufacturers are making the nice technical gear, it's just very difficult to stock and sell. Also, not all women want bright colours, so you're going to have to stock the olive greens and the blacks as well!
And by the by, women don't come in more shapes and sizes than men, I'm not sure what your logic is for that Snoweider. I think perhaps more women are interested in getting their clothing fit right than men are. In my anecdotal experience men are more likely to just size up for sleeve length (for e.g.) even if the rest of the jacket then doesn't fit, where as women are perhaps more likely to just accept that neither size fits and move on. In other words, more men will just put up with a fit that doesn't quite suit their body type. Just my own observations from working in a shop and not meant as a generalisation.
To the op, you mentioned trying to introduce different sizing types into a range. I think you'd have real trouble marketing this, also I'm not sure how many women would be comfortable asking if you have this is "pear shape"!
The outdoor market is largely fashion based, whatever technical kit you end up designing and selling it's probably going to help if you've got one eye on the highstreet fashion at the same time, otherwise you're going to find it very difficult to get anyone interested.
