4.7 / 5
Outstanding
Strengths
- Top-performing evaporative vest in 2026 field tests — dropped surface temp by 80°F in 3 minutes
- 3-layer construction balances cooling and dryness — fur stays relatively dry while the absorbent middle holds water
- Slips over the head with side-release buckles — easy on / off even for anxious dogs
Watch outs
- Evaporative cooling becomes less effective in very humid weather — best in dry-hot UK conditions
- Re-wet every 2–3 hours of active use — need access to water (river, pond, tap)
- £55–£70 UK retail is the premium end of the cooling-vest market
£65
