“ain't cheap with the added shipping, but better than buying a whole new helmet for the time being. just get two. stated as network, but fits my session exactly. they're not out of the session liner, it's just not listed and they playing games and you found it. as the saying goes.. it's the journey, not the destination. network/session liners appear to be the same. my first liner lasted about 800 miles of xc/trail mountain bike riding. really around 600, but at 800 they were done. the glue at the seam was the issue and likely due to sweating and getting wet, etc. (use) once or twice a week for about eight months. i doubt these replacement liners will last any longer, but it'll prolong this helmet from being put into the landfill. i will be looking elsewhere for my next helmet due to the longevity, durability and replacement expense of the liners, aside from the forward sitting fit that I seem to get that's pretty annoying. anyways, here's the liner replacement and thankfully it is made available, so thank you to smith for that. cheers and happy trails.”
