Waterproof backpacks come in a variety of sizes and styles. Although the truth is waterproof backpacks may have a slightly different look than what you're used to seeing with your tried and true old backpack.
In the past, a waterproof backpack was one made of canvas and were heavily waxed. Even the military used them. They kept a light rain from penetrating, but were heavy, and could never have kept all the electronic gear we use today dry enough. New material and construction methods were needed. Thank goodness today, waterproof packs are actually 100% waterproof and very light. To look for the best one follow this link
Active people who find themselves hiking in rain forests, or sea kayaking on rougher seas, snorkelers and scuba divers, search and rescue teams, or white water enthusiasts to name a few, need to be assured that their important gear will be safe wherever they need to go.
It's just a pain to always have to worry about getting to shelter before it rains, or tipping over in the raft, walking under a waterfall or accidentally dumping your pack out of the boat into the water. Heck – most of us have spent enough money on our essential electronic gear to fund a small country. Taking a chance of getting it wet whether at work or play just doesn't make sense.
In general, there are 5 classifications when it comes to identifying water repelling gear. It's a good idea to familiarize yourself with these differences before investing your money – don't make a mistake on the best pack to protect your gear:
Water Resistant: For those of that don't understand this point…this IS NOT waterproof. But it may be sufficient for your particular needs. It is resistant to light rain(if it's not out in it all day), and light splashes of water. Water exposure that's prolonged, or intense, or submersion will allow water to get in.
Waterproof in top-down water exposure conditions
Can be permeated by intense water pressure, or water pressure that comes in at odd angles This pack wouldn't be waterproof when submerged.
Waterproofing that creates a pack that will float, or tolerate a QUICK submersion.
Water can permeate with prolonged submersion, or submersion over 3 feet of water. Intense water pressure will allow water to penetrate.
Waterproof to at least 3 feet, but not over 12 feet of water
This is the first really waterproof rating. The depths given above can vary with the manufacturer. This pack is truly submersible, and can be used for a variety of water sports and working conditions. Swimming, snorkeling, and rafting/kayaking would be sports that would benefit using this pack. Water could penetrate this pack if it was submerged for more than 24 hours, but high pressure water won't be problem unless it's strong enough to compromise the material or the seams
Waterproof and Submersible over 12 feet
This is the pack to get if you regularly carry gear that must never get wet, or even damp – ever. Some of these packs can go as deep as 100 feet(check with specific manufacturers). Common applications might include: scuba diving, search and rescue, snorkeling, white water sports and other similar adventures.
Materials and Construction
Obviously, the fabrics used for truly waterproof construction must be…well, waterproof – that means that any pores in the fabric must be so small that water molecules can't slip through …that's really small. Even better, no pores at all would ensure no water seepage. These types of fabrics are available and most desirable for this kind of usage.
So if the material is waterproof, the construction of the pack from this material must not use any sort of
traditional stitching. When fabric is stitched, it necessarily creates holes…………. NOT waterproof. With these
special synthetic materials there are no traditional seams. The fabric pieces are seamed together via an ultrasonic device that literally melds the two pieces of material together. No stitching – no holes. Even if the stitching is coated with silicone, it will eventually de-bond and water will seep in and your sensitive gear will be toast.
The other nice thing about ultrasonic melding is it will reduce the weight of the pack by up to 30%. How great is that?
Some of the waterproof packs are equipped with purge valves, as well. These valves allow the user to inflate, or compress the backpack at will. It can even be used for a shower, or cooler (once you've removed all the gear you want to keep dry).
Traditional backpacks have all sorts of access points, zippers, and pockets. With a waterproof pack, the idea is to keep the access points to a minimum. . .like one. This presents fewer areas that need to be protected from in influx of any water. Many waterproof designs feature a singular top opening which is roll-top in construction, to further keep water out.
If you're just running between the raindrops now and then at work, go ahead and choose a water resistant pack. But for most of us, getting even one of our electronic or digital devices wet will ruin a really expensive item that will need to be replaced – probably immediately. Whether we work or play outdoors, we all haul around a pretty full complement of sensitive gear. Why take even a small chance of ruining that expensive investment with unnecessary water damage?
Say 'No' to water damage – Make your next pack waterproof .
