Got Questions?
Is the Heated Puffer Jacket safe to wear?
Is the Heated Puffer Jacket safe to wear?
Yes, very safe when used properly.
The Heated Puffer Jacket uses low-voltage USB power and our ThermoSphere™ heating system, which features insulated carbon fiber panels. Built-in temperature regulation prevents overheating, and all components are tested to meet international safety standards.
Does it actually warm me, or just trap body heat like a normal puffer?
Does it actually warm me, or just trap body heat like a normal puffer?
It heats faster than typical insulation.
Unlike regular jackets that only trap body warmth, the Heated Puffer actively generates heat. 21 ThermoSphere™ panels are built into the lining to warm your chest, back, arms, and shoulders in under 30 seconds, so you stay cosy even in freezing or damp conditions.
How long does the battery last?
How long does the battery last?
Up to 10 hours on low.
When paired with our recommended 10,000 mAh power bank, you can expect up to 10 hours on Low (25°C / 77°F), around 6–8 hours on Medium (35°C / 95°F), and 3–4 hours on High (45°C / 113°F). Runtime may vary depending on ambient temperature and the quality/capacity of your power bank.
Is the jacket heavy or bulky with the heating panels inside?
Is the jacket heavy or bulky with the heating panels inside?
Not bulky, it's as light as a regular puffer.
The ultra-thin ThermoSphere™ heating panels are flexible and integrated seamlessly into the jacket lining. This keeps the fit sleek and lightweight, never stiff or restrictive, so you can wear it as a daily jacket or layer it comfortably under other outerwear.
Can I wash the Heated Puffer Jacket?
Can I wash the Heated Puffer Jacket?
Yes, machine washable (remove the power bank).
Simply disconnect and remove the power bank, tuck the cable into its compartment, and wash on a gentle cycle. Air-dry only. Avoid bleach, ironing, or dry-cleaning to protect the ThermoSphere™ heating system.
Is the jacket waterproof or windproof?
Is the jacket waterproof or windproof?
Yes, water and wind resistant.
The outer shell is designed to repel light rain and block wind, keeping both you and the ThermoSphere™ panels protected. While it’s fine for everyday winter weather, we recommend pairing it with a waterproof shell for heavy downpours.
Can I control the level of heat?
Can I control the level of heat?
Yes, three adjustable heat levels.
The jacket has a simple one-button controller to cycle through Low (25°C / 77°F), Medium (35°C / 95°F), and High (45°C / 113°F) settings. Add a gentle boost of warmth for commutes, or crank it up to maximum when temperatures drop below freezing.
