Probably a really unconventional use but I wear these to bike commute in because the chamois is low profile enough that I just leave them on at work instead of changing. Really solid construction. I have four pairs.

Serge Schnegg



Très bonne qualité !

David Marshall



Kind of disappointing. Compared to A400 range, these offer little to no support/compression. I was advised by customer service to go down a size (even though I'm well out on size chart) but even then this product isn't of the standard which is the A400 range.

Eddie Han



Too tight.  I own 2 pairs of the previous TRI400, which are comfortable enough to wear for most of the day. These are much tighter than the previous version, which makes it quite uncomfortable around the crotch My waist is size 30, but I wear the large size because of my quads and glutes. (I do weightlifting) I wear these primarily for the gym because the A200 is ridiculously tight, and the DNAmic is uncomfortable when wearing for more than a few hours

Wore this top for my first mud run with swim section. 6 deg outside and close to freezing in water, this worked brilliantly and kept me warm on the 10k run. Thoroughly rate this kit.

This is my third pair of Skins TRI 400 Shorts in five years of competing in triathlons. I wore these for the Cairns Ironman and didn't have to think about any form of discomfort from my clothing. That to me is the greatest test of a technical race garment.

Great job, as I am getting on and have a few injurys from my younger years playing  Rugby and cricket. Ham string and groin problems have hampered me over the last few years. The support the shorts give is fantastic and gives me the confidence to push my running much more than before. I would recommend them to anybody and tell them "You get what you pay for."

Awesome great to swim in and also awesome to go bike riding with

Paul Cockburn



did the job perfectly well originally and would have highly recommended but the elastic tape around the bottom legs has come away from the shorts after around 3-4 washes so they have not lasted well at all.

Calum McGill



Great shorts, fit well with no chafing and quite comfortable to run in.
