I just started running and I love GapFit tights. It's nice to see that other, more experienced runners like them also. They have an insulted/fleece-lined version that is too warm for California most of the year, so I haven't needed anything warmer.
Features I love about my GapFit Fast tights:
~Great length
~Very little sheen
~The zip back pocket; other brands just have a foldover flap, so this is more secure
~My older ones have a drawstring
~Wicks away heat and moisture nicely
~With coupons & card rewards, price is even better than mainstream brands
~Sizes are usually easier to find (especially on sale) compared to Nike, UnderArmor, etc.
I do have Old Navy ones which are supposed to be compression, but are not, and the fabric is flimsier than Gap's. However, they're fair for the price and still have nice features (zip back pocket, drawstring waistband).
For super high performance, I've been wanting to try CW-X. If anyone here has input on them, it'd be appreciated!
