Eric Stengleinwrote a review of Race Face Flank Liner - Men's on August 4, 2020
Familiarity: I've used it once or twice and have initial impressions
I was expecting something closer to a good quality road chamois by the way the description reads. I ride both road and MTB. My expectations were a little to high. The chamois was sufficient for my typical MTB ride of up to 3 hours, but didn't live up to my thoughts of what a high performance Italian chamois is. I have enough Castelli bib shorts to know what Italian quality is.
The liner short fits well and has enough protection to give me the extra confidence to send bigger lines. D30 hip pads remove easily for washing. The fit and placement of the padding makes the protection unobtrusive. Pedaling uphill was not an issue and I never felt weighed down or uncomfortable with shifting pads sliding around. There is no coccyx protection. These would be perfect if the chamois was of slightly higher quality and coccyx protection. Perhaps Race Face doesn't get many dual road/MTB riders. Overall, I'm satisfied with them, but I'm not fully sold on the "triple density high quality Italian chamois" advertising.
