I ordered a few pairs of their shorts out of curiosity long before Goucher et al started with them. I'm pleased so far.
First of all, they come with pockets in good places. Its so hard to find pockets in shorts and I like to have a zipper pocket for keys/$ when I'm running/racing. I prefer to run light, and hate to wear a SPI belt if I can avoid it.
I have not had the chafing problem and have taken them out on plenty of 20+milers.
Also, I dry my running clothes in the dryer for convenience and I will give Oiselle credit that so far my shorts are still going strong. Usually the elastic is shot in the liner after a couple years with many brands (I know, I know.. I shouldn't dry them in heat... I'm willing to sacrifice the longevity for convenience).
Can't say I've ever ordered an Oiselle running shirt, most of the ones I see have 13.1 or 26.2 printed on them and scream hobby jogger. I prefer to stick with race shirts for distances I've run so don't see myself ordering those.... but there are plenty of gals out there that spend more than me on running wear.
I'm not a huge fan of a lot of brands when it comes to shorts for style/comfort so in that area, I hope Oiselle keeps at it!
