1. PU Leather
PU (polyurethane) leather is a fully synthetic, vegan-friendly alternative to genuine leather that comes at a much lower price. Typically, it costs 50–70% less than real leather, making it a popular choice for budget-conscious projects. But, as with most cost-effective options, there are some compromises involved.
Durability
One of PU leather’s main drawbacks is its reduced durability compared to genuine leather. Since it lacks the natural elasticity of cowhide, it’s more prone to punctures and tears when subjected to heavy use. Additionally, friction can wear it down over time. Standard PU leather generally lasts around 5–8 years, while genuine leather can endure for 10–20 years. Its non-breathable nature can also lead to moisture buildup and stickiness, which is a concern for items in prolonged contact with the body.
For applications that demand greater durability, marine-grade or silicone-based PU offers a longer lifespan of 8–10 years. These premium types include features like UV resistance and anti-fungal properties but come at a higher cost. Thicker grades (1.2mm–1.5mm) with reinforced backings are another way to boost structural integrity, especially for items that need to bear weight.
Cost (USD per yard)
Standard PU leather is significantly cheaper than genuine leather, with prices ranging from $8 to $15 per yard. Bulk orders of over 5,000 yards can often secure discounts of 10–30%. On the other hand, smaller quantities (500–1,000 yards) typically cost more, falling between $12 and $15 per yard due to setup fees. For specialty options, recycled or bio-based PU costs $18–$28 per yard, while high-performance silicone PU is priced between $20 and $30 per yard. Additional surface treatments, such as anti-microbial or UV-resistant coatings, can increase costs by 10–25%.
Water Resistance
PU leather offers decent water resistance, making it relatively easy to clean and maintain for everyday use. However, if your product requires full waterproofing – like gym bags or outdoor gear – marine-grade PU is a better choice, as it provides enhanced moisture protection and anti-fungal properties. Standard PU can handle light moisture but isn’t suitable for prolonged exposure or submersion.
Next, we’ll see how nylon measures up in terms of durability and cost.
2. Nylon
Nylon is a synthetic material known for its durability and versatility, often used in technical and athletic bags. First introduced in the 1930s as the world’s first synthetic fiber, it has since become a go-to choice for everything from gym bags to tactical gear. For instance, a 600D nylon backpack can weigh 30–40% less than a similar canvas bag while delivering equal – or even better – durability.
Durability
The strength of nylon is measured by its "denier" (D) rating, which indicates fiber thickness. Lighter grades like 210D to 420D are ideal for casual backpacks and totes, while heavier grades (600D to 1680D) are built for more demanding uses like luggage and professional gear. Thanks to its tight weave, nylon offers excellent abrasion resistance. Premium ballistic nylon, typically in 840D or 1050D with a 2×2 basketweave, takes durability up a notch with superior puncture protection. However, prolonged exposure to sunlight can weaken nylon fibers unless UV inhibitors are added. While polyester handles UV exposure better, nylon still outshines it in tear strength and overall toughness.
Cost (USD per yard)
Nylon fabrics generally range from $2 to $8 per yard. Lighter options (210D–420D) are priced at $2–$4 per yard, while heavier, more durable grades (600D–1680D) fall between $4 and $8 per yard. Premium varieties like ballistic nylon or Nylon 6,6 with TPU laminates can cost more than $8 per yard. Compared to polyester, nylon is typically 10–30% pricier for similar fabric types. However, its higher strength-to-weight ratio allows designers to use lighter materials, which can help offset the cost difference.
Water Resistance
Nylon naturally repels water better than canvas, but it isn’t inherently waterproof. To achieve waterproofing, additional coatings are required. TPU-coated nylon offers excellent water resistance, with Hydrostatic Head ratings of 10,000–20,000+ mm, and resists mildew when properly dried. For athletic bags designed to carry wet or damp gear, a TPU laminate or a heavy PU coating is a better choice than relying solely on a durable water-repellent finish. Cleaning nylon is simple – just wipe it down with a damp cloth.
Weight Capacity
One of nylon’s standout features is its high tensile strength, making it perfect for heavy-duty hiking packs and travel bags. Its flexible molecular structure helps distribute stress evenly, reducing the risk of straps snapping under heavy loads. For projects targeting athletes or frequent travelers, nylon’s lightweight yet strong build makes it an excellent choice for creating bags that can handle heavy contents without unnecessary bulk.
Next, we’ll take a closer look at canvas as another material option for Kickstarter bags.
3. Canvas
Canvas stands out as a more traditional material option, offering a blend of timeless style and sturdy construction. Made from cotton or cotton-polyester blends, this woven fabric develops a distinctive patina over time, adding character as it ages. Its durability and aesthetic appeal make it a popular choice for various types of bags.
Durability
Canvas is known for its impressive strength, particularly for static uses. A 12oz canvas can endure 25,000–40,000 cycles in Martindale abrasion tests, with a tear strength ranging from 45–65 N in warp and weft directions. Heavier canvas (16oz–20oz) is even more resistant to tears and maintains its shape under heavy loads. However, it comes with a tradeoff: canvas is much heavier than nylon. For instance, a typical canvas backpack weighs around 800–1,200g (1.8–2.6 lbs), compared to 500–800g (1.1–1.8 lbs) for a nylon equivalent. While canvas excels in static durability, nylon is often the better choice for mobile uses where lighter weight and abrasion resistance are key.
Cost (USD per yard)
The price of canvas depends on its weight and any treatments it has undergone. Basic cotton canvas typically costs $8–$15 per yard, while higher-quality duck canvas is priced between $15 and $25 per yard. Specialty treatments like waterproofing can push the cost to $25–$40+ per yard. Poly-cotton blends, which combine natural aesthetics with easier maintenance, are more affordable, ranging from $4–$7 per yard. Waxed canvas, prized for its water resistance and vintage look, is usually priced at $8–$12 per yard. For budget-conscious projects, 10–12oz canvas offers a good balance between cost and structural integrity.
Water Resistance
Untreated canvas is naturally absorbent, soaking up about 7–8% of its weight in moisture. This makes it less ideal for bags exposed to wet conditions or used for athletic gear. However, treatments can address this issue. Waxed canvas provides moderate-to-high water repellency and can be re-waxed to maintain its effectiveness. PU coatings offer even better waterproofing with a smooth finish, making them suitable for outdoor gear. Without proper treatment, though, canvas is vulnerable to mold and mildew in humid environments, so protective coatings are essential for long-term use in wet conditions.
Weight Capacity
Canvas shines when it comes to carrying heavy loads. Its tight weave minimizes sagging and helps maintain a bag’s shape, making it ideal for messenger bags, laptop carriers, and duffel bags. The material’s natural stiffness supports structural integrity, even when fully packed. Additionally, canvas is easy to repair – small tears can be fixed with basic sewing skills, extending the life of the bag. This repairability, combined with its durability, makes canvas a solid choice for applications where strength and longevity are priorities.
