Imagine standing outside in the scorching summer heat or the biting winter nights for more than five minutes. Sounds uncomfortable, right? Now think of the gig and delivery workers that have to endure these extremes every day to finish their jobs and earn their wages. This got me thinking if I could develop a product that would make these harsh conditions bearable.

Problem: Delivery workers do not have proper protection against harsh weathers, which decreases their efficiency.

Solution: I propose a Dual-Season PCM Jacket – a mid-weight jacket designed specifically for gig and delivery workers. The jacket uses Phase Change Materials (PCM) to regulate temperature. With simple, swappable inserts, it can provide cooling relief during summers and insulation during winters, making it usable throughout the year without needing two separate jackets.

How it Works:

Summer Mode: PCM cooling packs absorb body heat and release a cooling effect, helping workers stay comfortable even under direct sunlight.

Winter Mode: Thermal inserts or insulated layers can be swapped in, trapping body warmth and shielding workers from cold night shifts.

Ease of Use: The swappable mechanism is simple, quick, and requires no special training. Jackets can be recharged or refreshed during breaks, ensuring consistent comfort.

Why it is better than existing solutions:

Fan Jackets:

• Use small battery-powered fans to circulate air for cooling only.
• They are bulky and noisy, with limited battery life (2–4 hours).
• They do not offer no protection against cold weather.

Dual-Season PCM Jacket:

• The jackets are season-adaptive — provides both summer cooling and winter heating in the same jacket.
• They use passive PCM technology, instead of fans, motors, and wires.
• This is a cost-effective option as swappable PCM packs last multiple seasons and do not require electricity.

Who Benefits:

• Delivery Workers: Safer, more comfortable working conditions that improve health, focus, and efficiency.
• Delivery Companies: Improved worker satisfaction, reduced fatigue-related delays, and potential branding benefits by showing worker care.
• Society: Healthier gig workers mean better service reliability, and an overall more humane work culture.

Why It Matters:
Extreme weather shouldn’t be a barrier to earning a livelihood. By giving delivery workers protective gear that adapts to the seasons, we can improve both their quality of life and their productivity.

Future Scope:
This concept can be extended to other high-exposure jobs—traffic police, construction workers, security guards—creating a larger impact on worker well-being across industries.

Technical Details:

1. Material/Design: Lightweight, breathable, and moisture-wicking polyester blend (drifit-like), ensuring comfort during long hours of work and preventing overheating or sweating.
2. Cooling Mode (Summer):

• Organic PCM packs with a melting point of 28–30°C, absorbing body heat and providing a consistent cooling effect for up to 2–3 hours per insert.
• Swappable packs fit into discreet inner pockets; can be refreshed with ice packs or cooling station breaks.

3. Insulation Mode (Winter):

• Thin thermal PCM or synthetic insulated layers that trap body heat without adding heaviness, and keeps wearer warm for typical 8-hour shifts.
• Swappable in seconds using the same inner pockets, maintaining the lightweight feel.

4. Maintenance & Recharge:

• PCM packs are reusable and can be cooled or warmed depending on the mode.
• Fabric is machine washable; PCM inserts can be removed before washing.
• Packs can be recharged or swapped during breaks.

Areas of Improvement:

• Weight: Exploring lighter materials could further reduce fatigue during long shifts.
• Comfort: Optimizing fit, flexibility, and ventilation to enhance wearer comfort.
• Duration Between Recharges: Extending the effective cooling or heating time of PCM inserts would reduce the need for frequent swaps and breaks, improving shift efficiency.

The Dual-Season PCM Jacket transforms how gig and delivery workers face extreme weather. This jacket is more than just apparel. It’s a performance tool. It improves health, focus, and efficiency for gig workers while staying practical, affordable, and wearable, and sets a new standard for wearable workplace innovation.
