Equipment protection in wet conditions

Before we start protecting our gear, we need to think about when and what we are doing. Different steps must be taken when going for a light trekking in the hills where the worst that can happen is a solid downpour. More serious measures must be considered for something like a canoeing excursion.

When packing, protection against water in case of a sudden weather change or backpack drop is essential

Despite the differences, there is one common thing that will protect our belongings from water. It is a sealable dry bag – completely waterproof and usually protected with a roll-top closure. It can be heavy but it is my favorite item for wet conditions load carrying. The sack goes empty into the backpack first, then I pack my belongings. Care must be taken when packing sharp, pointy objects to prevent damage to the fabric. The best way to prevent this is to simply roll these objects in soft clothing.

One of the solutions for protecting our gear is to utilize a dry sack, which is place inside the backpack

Dry sacks have various sizes and are usually secured by a roll-top. Mass and susceptibility to damage are the main disadvantages

Before we decide on using a dry sack for protection, it is important to think about what goes into it and how do we expect the water to affect us. Let`s say we are going for a mountain stroll and heavy rain is coming. When it happens, the first thing we will want is our jacket and gaiters. So, do not put those into the dry sack. Why? When the rain is falling, the last thing we want to do is open the sack and let the rain into our well protected, dry storage. It is better to place those items in an auxiliary pocket or outside compartment. Simmilary, avoid placing food into the sack. Hunger can strike anytime (especially during a hike) and food is usually packed in waterproof bags anyway. Think about this when packing – some items can and will get wet but this will allow for other gear to remain dry.

Anything that must be put on in case of rain should not be placed in the dry sack. Things like jacket and gaiters should be located in an auxiliary pocket or outside compartment

A backpack has limited space. It is thus wise to sacrifice some space for equipment that can get wet. It makes keeping the rest of the pack dry much easier

If we decide not to use the dry sack, think about the fabric of the backpack itself. Laminated Cordura type of material is generally waterproof. Even though this fabric will not let water through, the seams, zippers and other perforations will. If complete waterproofing of the pack is important, consider using an additional slipcover. These come in a variety of sizes, colors and prices. But remember – these covers protect only the majority of the pack. The back facing side remains unprotected. Slipcovers are usually lightweight but also not very durable. Rough handling, branches and rocks can easily damage those. This is the main reason I do not like this type of cover.

When deciding on a dry sack, think about the backpack fabric itself. Sometimes it is not necessary to use additional protection

I will conclude with a personal story. I recently visited a mountan lodge. The backpack was wet on the outside and I left it in this damp condition for the night. Even though water did not get inside while raining, the dampness seeped through into one of the compartments and in the morning I found my jacket soaking wet. Conclusions? Always try and unpack and air equipment out whenever conditions allow us to do so.

Good luck on the trail and everlasting dryness in the backpack
