What is the difference between the Oxygen...
What is the difference between the Oxygen SO Bib Tight and the Xenon SO Bib Tight?
First, the Oxygen is available with or without a chamois, while the Xenon is only available with chamois. The Xenon chamois is very road specific and minimalist with density only where needed, while the Oxygen chamois is more plush, though still with varied densities where it matters.
Second, the Xenon is a little warmer, with slightly thicker brushed fleece backing, though the Oxygen is still VERY warm.
Third, the Xenon is cut a little more aggressively (for a more stretched out position on a road bike).
Hope that helps,
