I've been doing quite a bit of women's gear research lately, so I'll offer some information I've stumbled upon. I just bought a setup for my soon to be wife. I went with a Bataleon FeelBetter because they are noob friendly. The TBT design tends to catch less of an edge, which as a beginner can get really old and painful. I found a 2013 Bataleon FeelBetter for $288 shipped from EternalSnow (link below). I also picked up a set of Rome Madison's for $104 from EVO. And grabbed a pair of Vans Veins for $160 from EVO as well. A complete package for under $600 and it's all top notch gear that she will be able to progress with.

Don't be like all the other noobs on the hill, which is what you will be if you buy a Burton.
