Hey Pooks,

I've tried both.

Sugar Knicker
Pros: Comfy, nice chamois, comfortable opening at leg
Cons: Extremely low rise, thin fabric (this is a pro for me, but might be a con for you if you want them for cool weather.)

Ergo Sensor Knickers
Pros: Thick, durable fabric, would probably keep you warmer than the Sugars. Pretty and slimming blue contrast stitching.
Cons: The chamois is nice but might not be appropriate for long rides. Blue contrast stitching might limit you in terms of matching colors.

Have you considered Shebeest Pedal Pushers? I'm a big fan. And of course I've heard wonderful things here about the Etxe Ondo knickers, but I'm waiting for the warmer weather styles to come in.

Happy shopping,

Cari
