Product Introduction
Are you looking for a marketing tool that is both refined and powerful enough to bring your brand closer to your customers? Bobby promotional backpacks in bulk are exactly the answer that Hop Phat wants to introduce to your business today.
More than just a shoulder bag, this product is a mobile billboard — present everywhere, at all times — from offices to classrooms, from buses to conference halls. Let’s explore the special features that make promotional backpacks the number one choice for modern brand communication campaigns.
Polyester Fabric – Where Durability Meets Aesthetics
420D/600D Polyester Fabric: The Choice of Smart Brands
Hop Phat uses 420D/600D Polyester fabric as the primary material for its promotional backpack line. This is not a random choice. This type of fabric is renowned in the industrial textile industry for its exceptional durability.
Did you know? The number “420D” or “600D” represents the thread density (Denier) — the higher the number, the thicker and more durable the fabric. With this thickness, the backpack can:
- Naturally repel water when caught in light rain or splashing
- Withstand high friction from daily use
- Maintain its shape without sagging or losing form after months of use
- Clean easily with just a damp cloth or machine wash
The special feature? The surface of Polyester fabric is the perfect canvas for logo printing. Colors adhere firmly, come out sharp, and last long — something canvas or cotton fabrics typically cannot achieve at the same price point.

Diverse Color Palette – Your Brand Story Through Every Shade
Hop Phat offers three primary color options for promotional backpacks:
| Color | Meaning | Suitable Industries |
|---|---|---|
| Black | Professional, elegant, refined | Finance, Banking, Law, Technology |
| Blue | Trustworthy, stable, energetic | Energy, Healthcare, Education, Telecom |
| Orange | Dynamic, creative, passionate | Startups, F&B, Retail, Events |
The decorative panels use contrasting solid Polyester fabric to create a subtle aesthetic accent — not so bold as to lose professionalism, yet striking enough to capture attention. That is the design philosophy we pursue.
Ergonomic Design – Comfort Built for Everyone
Golden Dimensions: 43–45 cm × 30–32 cm × 16–18 cm
Why did Hop Phat choose these dimensions? The answer lies in versatility and optimized user experience.
The 43–45 cm height is just right to:
- Fit a 14–15.6-inch laptop snugly (the most popular sizes today)
- Hold A4 documents without folding
- Avoid being too tall for smaller users to feel comfortable
The 30–32 cm width and 16–18 cm depth create a 20–25 liter storage space — the ideal volume for both students and office professionals. You can carry everything needed for a full workday without feeling overstuffed.
5-Compartment System – Smart Organization Down to Every Detail
Forget the single-pocket backpack that has you searching for a pen all morning. Hop Phat designs 5 functional compartments to keep everything organized:
Three main/secondary front compartments:
- Large main compartment with Size 8 zipper: Spacious room for laptop, books, and clothing. Soft padded lining protects electronics
- Vertical front zipper pocket: Quick access to phone, wallet, and keys while on the move
- Small inner pocket: Dedicated space for ATM cards, business cards, USB drives — items most likely to get lost
Two mesh side pockets: This is the detail most users love. The stretch mesh material holds a 500–750 ml water bottle securely, while its breathable structure dries quickly. You can grab your water bottle without unzipping the bag — convenience down to the last second.
Airmesh Back Padding – European Breathability Technology
If you’ve ever endured the discomfort of a sweat-soaked back from wearing a backpack all day, you’ll understand the value of Airmesh padding technology.
Hop Phat applies this design with:
- 3D mesh layer creating airflow space between the back and the bag
- Lightweight EVA foam padding distributing pressure evenly across the back surface
- Vertical air-channel design reducing contact heat by 40–50%
The shoulder straps are similarly padded, measuring 5–6 cm wide to prevent strap marks on shoulders even when carrying heavy loads. The black padding is both elegant and easy to keep clean — a small but meaningful detail for frequent users.

Premium Accessories – Every Detail Makes a Difference
YKK Nylon Zippers – Global Industry Standard
Did you know that 60% of backpack failures come from broken zippers? Hop Phat understands this and uses only high-quality Nylon zippers:
- Size 8 for the main compartment: Strong enough for thousands of open-close cycles without jamming
- Size 5 for secondary pockets: Softer and suited to the smaller size
- Metal zipper pulls: Rust-resistant and easy to grip even with wet hands
Zippers are tested 200 open/close cycles before leaving the factory — ensuring absolute quality.
210D Polyester Lining – Dual Protection for Your Belongings
The inner lining is more than just a plain layer of fabric. With 210D black Polyester (or matching tones), it creates:
- A second waterproofing barrier
- A smooth surface that doesn’t scratch laptops or tablets
- Easy-to-wipe surfaces if water or food spills inside
Silk-Screen Printing – When Your Logo Becomes Art
Traditional Silk-Screen Technique – Durability Beyond Time
In the era of digital printing, why does Hop Phat still trust traditional silk-screen printing?
The answer is durability. Silk-screen ink penetrates deep into the fabric fibers, forming a strong chemical bond. After 100 washes, the logo retains 95% of its sharpness — a figure that heat transfer or DTG printing rarely achieves.
Our silk-screen printing process:
- Logo design and color separation per specification
- Individual mesh screen made for each color
- Manual printing of each color layer, air-dried naturally
- Heat-set at 150°C to permanently fix colors
A White or Blue logo on dark fabric creates perfect contrast. From 5–7 meters away, your brand name remains clearly legible.
Flexible Print Placement – Maximize Communication Impact
- Main front panel: The prime position for the main logo, 15×20 cm in size
- Shoulder straps: Print slogan or website — always within eyeline
- Front pocket flap: Secondary message or hotline number
Every day, a single backpack is seen by 50–100 people on the street. Over one year, that translates to 18,000–36,000 brand impressions from a single product. The real marketing cost comes down to just a few cents per impression!
Minimum Order of 100 Units – Flexible for Every Scale
Hop Phat understands that not every business needs thousands of promotional items. That is why we set the minimum at just 100 units — suitable for:
- Small and medium businesses hosting customer appreciation events
- Startups building initial brand awareness
- Branches or departments needing staff gifts
- Schools and training centers rewarding outstanding students
With 100 units, the per-unit cost is extremely competitive while maintaining premium quality. You don’t need to invest hundreds of millions to run an impressive marketing campaign.
Real-World Applications – From Office to Campus
Imagine these scenarios:
In an energy corporation like EVN: 500 backpacks gifted to employees on the company’s anniversary. Every day commuting, they carry a bag with the company logo — colleagues feel proud, and outsiders recognize it as a reputable enterprise.
In a technology company: Backpacks serve as onboarding gifts for new employees. They use them to carry laptops and documents — both practical and helping new hires feel immediately integrated.
In a bank: 200 backpacks gifted to VIP customers opening credit cards. Every time they use the bag, the bank’s brand is naturally reinforced.
In a university: Backpacks awarded to scholarship recipients. This is not just a material gift — it is a symbol of recognition.
