I am a female and I own some Oiselle clothes. I have no affiliation with the company -- don't know anyone there, not a member of the "flock", etc.
I like the tights and several of the tanks and long sleeve shirts and sweaters. (I personally don't wear shirts with sayings on them when I run, so no 26.2, etc. for me.) (For example, I prefer the Oiselle winter-weight tights to athleta and the running brands.)
Not quite as big a fan of the shorts, at least for now. My sense is that the company initially targeted a tall and lanky body-type with its designs. This makes sense -- many runners have this build, including (from what I can see) the company's founders. I am shorter and have a more muscular build, so some of the shorts did not really work for me -- the proportions were just not right. I have not tried the newer shorts designs -- I believe they released longer versions of some of the shorts, etc. to respond to customer feedback.
I have not tried any of the sweatpants, sweatshirts. I just can't see spending so much money (70-plus ) on sweats. For me, price is the biggest negative when looking at Oiselle's future prospects. I like the fabrics, and I appreciate that they don't use sweatshop labor. But, I would rather they not make sweats (and other similar products) at all vs. charge more than $70 for them. If I am going to splurge (vs. buying Nike, etc. gear at TJ Maxx,), I want the product to be something special -- a really comfortable, useful item that I can use over and over during marathon training. I am not inclined to spend tons of money on sweats that I might not even wear to the grocery store.
As for the company, I like the focus on female athletes, and I appreciate their efforts (even if small) to support post-collegiate runners. Clearly, they are not paying a ton -- several of their athletes seem to have left for Brooks, for example. But, even if it's mostly gear and some travel/ race support, it's better than nothing. I do NOT like the lily white list of sponsored athletes. Clearly, Oiselle is not the only company with a less than diverse roster of sponsored athletes. But, I think that unless buyers of product express support for diversity in sponsorships, well . .. things won't change. So I am expressing my view publicly . . . .
