REI, and some other vendors have allow a return after trying the saddle. For this type of item, I find that the higher cost is justified by the ability to do this. REI is one year, full refund.
I’m glad to know that a saddle without cutouts has as much likelihood of suiting her as any other, since we aren’t inclined to “buy and try - repeat”. She’s being a good sport about all this (equipping for a bike tour with not much time on road frames, for long stretches of time) so I don’t want her to miss any chances to keep avoidable discomforts at bay. Thanks
