The Zero Degree vs. Your Old Shorts.
Spoiler: the swim trunks in your drawer were built for the pool, not for 34°F water with a grudge.
Numbers are nice. Hear it from the guys actually standing in the water. ↓

Real reviews from real athletes. No anonymous, no filler.
"First plunge wearing these I actually stayed in for the full three minutes instead of bailing at ten seconds. Total game changer for actually building the habit."
"Was skeptical it'd feel too hot out of the water. It doesn't. Wear them straight into the sauna. The neoprene where it counts is the whole point."
"Look, nobody wants to talk about it, but these solve the one problem that kept me from plunging consistently. Bought a second pair the next week."
Reading's fine. Seeing's better. ↓
The Stuff You're Too Polite to Ask.
Cold water immersion is serious. So is the gear you wear into it. Straight answers — including the ones guys won't say out loud at the plunge club.
How is this different from regular compression shorts?+
Regular shorts are built for dryness and movement. The Zero Degree Short has a 1.5mm neoprene inner liner — the same material wetsuits use — that traps a thin warm layer against your skin and slows the cold transfer where it matters most. It's the only short built specifically for the cold plunge.
Will it keep me too warm after the plunge?+
No. The outer shell is a four-way stretch performance fabric that breathes and wicks. The liner is ultra-thin — it insulates in cold water without overheating at air temperature. Most guys go straight from the plunge into the sauna without changing.
Is the protection… you know, down there real?+
Very. The liner sits exactly where the cold hits first and hardest, taking the edge off the initial shock so the first ten seconds don't end your session. That's the whole reason the short exists.
What size should I order?+
True to size. If you're between sizes, size up — the Performance-Lock waistband holds position regardless. There's a full size guide on the product page.
What if they're not right for me?+
30 days, full refund, no interrogation. Try them in the plunge. If they don't deliver, send them back.
