Frequently Asked Questions
What makes a roll top backpack truly waterproof, and how does it differ from water-resistant?
A truly waterproof roll top backpack achieves its protection through a combination of fabric and closure design. The fabric is typically a thermoplastic polyurethane (TPU) coated nylon or polyester, or a PVC-coated material. These coatings create a non-porous barrier preventing water molecules from penetrating. Crucially, waterproof backpacks are often welded, not stitched, as stitching creates tiny holes. The roll-top closure, when properly executed (typically 3-5 rolls), compresses the material and creates a tight seal, further preventing water ingress, and is often paired with a clip closure for added security.
Water-resistant backpacks, conversely, utilize fabrics treated with Durable Water Repellent (DWR) coatings. While DWR effectively sheds light rain and splashes, it’s not a permanent solution and will wear off over time, requiring re-application. Water-resistant materials breathe to some extent, making them more comfortable, but also allowing water to eventually penetrate under sustained exposure or pressure. A hydrostatic head test measures water resistance; waterproof materials generally exceed 10,000mm, while water-resistant materials typically fall between 1,500mm and 5,000mm.
How important is the denier (D) of the fabric in a waterproof roll top backpack?
Denier (D) refers to the weight in grams of a 9,000-meter length of fabric. A higher denier generally indicates a thicker, more durable fabric. For waterproof roll top backpacks, denier is a significant factor, particularly regarding abrasion resistance and tear strength. Lower denier fabrics (e.g., 210D) are lighter and suitable for general use, but may be more prone to damage from rough surfaces or sharp objects.
Higher denier fabrics (e.g., 600D or higher) offer superior durability, making them ideal for demanding activities like hiking, kayaking, or commuting in harsh conditions. However, increased denier also means increased weight and potentially reduced flexibility. A good balance is often found in the 420D-600D range, providing a reasonable combination of weight, durability, and cost. Consider the intended use; a casual commuter might prioritize lighter weight, while an adventurer will likely favor robustness.
Are all roll top backpacks genuinely waterproof, or is there a risk of leakage?
While designed to be waterproof, achieving complete waterproofness relies heavily on proper use and the quality of construction. Even with a waterproof fabric and roll-top closure, leaks can occur if the closure isn’t rolled tightly enough, if the clips aren’t secured, or if the backpack is submerged for extended periods beyond its specified waterproof rating. Seam welding quality is also critical; poorly welded seams are a common point of failure.
Furthermore, some backpacks advertise “waterproof” but may only be IPX-rated for splash resistance, not full submersion. IPX ratings indicate levels of protection against water ingress, with higher numbers signifying greater protection. Look for backpacks specifically stating they are fully waterproof and ideally, those with independent testing or certifications. Regularly inspect the roll-top mechanism and seams for wear and tear to maintain waterproof integrity.
What capacity roll top backpack is best for different activities (commuting, hiking, travel)?

Travel often benefits from a versatile 40-60 liter backpack that can function as both a carry-on and a weekend bag.
Consider the bulk of your gear. Hiking and camping gear tends to be more voluminous than clothing or work essentials. Also, think about accessibility. Larger capacity backpacks often feature multiple compartments and external attachment points for organizing and securing gear. A smaller, streamlined backpack is preferable for commuting where maneuverability is key.
How do you properly roll and close a roll top backpack to ensure a waterproof seal?
The key to a waterproof seal is compression and multiple rolls. Begin by ensuring all items inside are evenly distributed and not straining the backpack’s seams. Start rolling from the bottom, pressing firmly with each roll to expel air and compress the contents. Aim for at least three, ideally four or five, tight rolls. The tighter the roll, the more effective the seal.
After rolling, securely fasten the clips or straps provided. These clips add an extra layer of security, preventing the roll from unraveling. Regularly check the tightness of the roll and the security of the clips, especially during activities involving movement or exposure to water. Practice rolling the backpack before relying on it in a critical situation to ensure you’ve mastered the technique.
What are the pros and cons of TPU vs. PVC coated fabrics in waterproof roll top backpacks?
Both TPU (Thermoplastic Polyurethane) and PVC (Polyvinyl Chloride) are commonly used coatings for waterproof fabrics, but they differ significantly in their properties. TPU is generally considered more environmentally friendly as it’s recyclable and doesn’t contain phthalates, harmful plasticizers found in PVC. It’s also more flexible and abrasion-resistant, making it more durable and comfortable to use, even in cold temperatures. However, TPU is typically more expensive than PVC.
PVC is a more cost-effective option, offering excellent waterproofness and durability. However, it’s less flexible, can become brittle in cold weather, and its production and disposal raise environmental concerns due to the use of phthalates and the difficulty of recycling. While PVC is still widely used, the trend is shifting towards TPU as consumers become more environmentally conscious and prioritize long-term durability.
