Why Aren T Backpacking Packs Waterproof?.
Demystifying the Waterproof Backpack Paradox: Why Waterproof Backpacks Aren't Always the Answer
As an avid hiker, you're well-versed in the challenges of traversing the great outdoors, from unpredictable weather patterns to unpredictable terrain. One constant companion on your adventures is your trusty backpack, the workhorse that bears the weight of your essentials. And while you might expect it to be impervious to the elements, the reality is that most backpacking packs aren't fully waterproof.
Why is this the case? While it seems counterintuitive, there are several reasons why fully waterproof backpacks aren't the norm in the backpacking world. Let's delve into the factors that contribute to this seemingly paradoxical situation.
Challenges of Seam Sealing
The most common reason why backpacks aren't fully waterproof is the challenge of seam sealing. Seams are the weak points in any fabric, and they allow water to penetrate, even if the fabric itself is waterproof. To make a backpack truly waterproof, all seams would need to be individually sealed, a process that is both laborious and expensive.
Trade-offs in Material Properties
Waterproof materials, such as those made from polyurethane and silicone, often sacrifice breathability for their water-resistant properties. This can lead to issues like condensation inside the pack, which can not only make your gear damp but also promote the growth of mildew and mold.
The Appeal of Flexibility
Backpacks are designed to carry a variety of gear, from bulky sleeping bags to delicate electronics. A fully waterproof backpack would restrict this flexibility, as it would be difficult to access gear without compromising the waterproofing.
Alternative Solutions: Dry Sacks and Pack Liners
While fully waterproof backpacks may seem like the ideal solution, there are effective alternatives that address the concerns mentioned above. Dry sacks are lightweight, waterproof bags that can be used to store gear individually, ensuring that even if water penetrates the pack, your belongings will remain dry. Pack liners, also available in waterproof or water-resistant varieties, can be placed inside the backpack to provide an additional layer of protection.
Considerations for Specific Needs
The choice of whether or not to use a fully waterproof backpack depends on individual needs and preferences. For those who hike in areas with consistently wet weather or who carry sensitive electronics, a fully waterproof backpack may be a worthwhile investment. However, for most backpackers, a combination of dry sacks and pack liners provides adequate protection without sacrificing the advantages of a more breathable fabric.
Conclusion: Striking a Balance
Backpacking backpacks offer a balance of features, designed to meet the needs of outdoor enthusiasts. While fully waterproof backpacks may seem like the ultimate solution, there are practical alternatives that offer protection without compromising flexibility or breathability. By understanding the trade-offs and considering individual needs, backpackers can make informed decisions about their backpack choices, ensuring that their gear stays dry and their adventures continue uninterrupted.
