The VX Carbon is back in stock - 4,000 km wear-tested, 42% energy return
78gsm ripstop · 68g · zip rear pocket
Sixty-eight grams of 78gsm ripstop with a 5-inch inseam and a split hem that clears the quad at full extension. The waistband is a 38mm bonded band with a silicone gripper strip - no drawcord bounce, no roll-down on a fast finish.
Theo Marchand ran the 2025 indoor season in a pre-production pair and asked for exactly one change: a zip rear pocket sized to a phone, 155mm by 85mm, positioned high enough that it does not slap. Two side stash pockets hold gels.

I rotate the Meridian through every easy day of a marathon block and measured the rebound myself at 640 km - still within 4% of new. The 10mm drop is forgiving at the end of a 35k when my form starts to fall apart.
Twelve weeks of heavy cleans and box jumps and the waistband has never rolled once. Compression still holds at the calf after about forty washes, which is more than I can say for the pair I replaced.
Wore the Stormline through the back half of a 100k in horizontal rain and stayed dry under it. Docking one star because the hood is cut tight over a cap - size up if you run in a visor.
I ran the Pulse against my chest strap for six weeks of track sessions. Average gap was around 2 bpm even on 400m repeats, and being able to pull raw FIT files without paying a subscription sealed it.
