Sagu PCM Cooling Neck Ring

Tested at 104°F. Still cooling after 2 hours.

Most cooling products fail in 20 minutes. Vilos uses 99% PCM (Phase Change Material) to deliver dry, consistent 64°F cooling — no batteries, no water, no mess. Just freeze for 20 minutes, snap it on, and work.

Why Workers Are Switching to Vilos

• 2-Hour Cooling at 104°F — 3-6x longer than Amazon PCM generics
• 360° Segmented Gel-Cell Design — full neck coverage, not a narrow U-shape
• Completely Dry — no condensation, no dripping, no soaked shirts
• 20-Minute Quick Refreeze — fridge, cooler, or ice water
• Skin-Safe 64°F (18°C) — cool enough to work, zero frostbite risk
• Featherweight 5.1 oz (145g) — forget you're wearing it

How It Works

1. Freeze — 20 minutes in any fridge, cooler, or ice water
2. Snap On — 360° wrap with snap closure, no ties or adjustments
3. Swap & Repeat — grab the fresh one from your cooler bag for all-day cooling

2-Pack All-Day Kit — The Smarter Way to Beat the Heat

The #1 complaint about PCM products is they don't last long enough. Our 2-Pack + Insulated Cooler Bag solves this — swap rings for continuous cooling through your entire shift. Zero downtime.

What This Product Is NOT

Vilos is not a portable AC. It won't make you feel "cold." It takes the dangerous edge off extreme heat so you can keep working safely. In 110°F+, expect 60-90 minutes per ring — that's exactly why the 2-Pack rotation system exists.
