How to Waterproof Your Bikepacking Setup

The Waterproof Mindset

Here is the uncomfortable truth about bikepacking in rain: you will get wet. Your body, your bike, your shoes, and the outside of your bags will all get soaked. The goal of waterproofing is not to stay completely dry—it is to keep your critical items dry inside your bags while managing the moisture that inevitably gets in. The difference between a miserable rainy trip and a manageable one is not how wet you get during the day, but whether you have dry clothes and a dry sleeping bag waiting for you at camp.

This mindset shift is important because it changes how you pack. Instead of relying on your bags to be waterproof (most are water-resistant at best), you waterproof individual items inside your bags. This layered approach means that even if water penetrates your outer bag, your critical gear stays dry inside its own waterproof layer.

Think of waterproofing as a system with multiple redundant layers, not a single barrier. The more important the item, the more layers of protection it gets. Your sleeping bag gets the most protection; your dirty socks get the least. Here is how to implement this system across every part of your setup.

Waterproofing Your Bags

Bikepacking bags fall into three waterproofing categories: fully waterproof (welded seams, roll-top closures), water-resistant (coated fabrics, covered zippers), and not water-resistant (basic nylon or canvas). Most quality bikepacking bags from brands like Revelate and Apidura fall into the water-resistant category—they will handle light rain and spray but will eventually wet through in sustained heavy rain.

The Ortlieb Cockpit Pack is one of the few truly waterproof bikepacking bags, using Ortlieb's welded PVC construction. If you ride frequently in wet conditions, having at least one fully waterproof bag for your most sensitive items—electronics, documents, emergency clothing—is a worthwhile investment.

For all other bags, line them with lightweight dry bags or waterproof stuff sacks. A 5L dry bag inside your frame bag and a 10L dry bag inside your handlebar roll adds about 60g total and provides genuine waterproof protection regardless of your outer bag's water resistance. Look for dry bags with roll-top closures—zipper-style dry bags eventually leak at the zipper.

The Revelate Designs Spinelock 16 seat bag uses VX21 fabric with sealed seams that handles rain well, but even so, lining it with a compactor bag (the heavy-duty trash bags used for trash compactors) adds a virtually weightless waterproof layer. Compactor bags are a bikepacker's secret weapon—they are tougher than regular trash bags, cost pennies each, and weigh almost nothing.

Keeping Your Sleep System Dry

Your sleep system is the single most important thing to keep dry. A wet sleeping bag—especially a down bag—loses most of its insulating ability and can take days to dry out in the field. Preventing this should be your top waterproofing priority.

Double-bag your sleeping bag: first into a waterproof compression sack (Sea to Summit and Granite Gear make excellent ones), then into your handlebar roll or seat bag. The compression sack serves double duty—it compresses the bag for packing and provides a sealed waterproof barrier. Even if your outer bag gets completely soaked, your sleeping bag stays dry inside its compression sack.

Your sleeping pad is less critical since most inflatable pads are inherently waterproof. But keep the valve clean and dry, and store the pad in a way that prevents the stuff sack from collecting water. A damp pad inside a sealed bag will eventually grow mildew.

For your shelter, a wet tent or tarp is annoying but not dangerous—you will be inside it, not wrapped in it. If possible, shake off excess water and separate the wet fly from the dry inner tent before packing. On wet-weather trips, accept that your shelter will be damp and pack it in an exterior location where it will not soak other items.

Protecting Electronics

Modern electronics are more water-resistant than ever—many phones and GPS units carry IP67 or IPX7 ratings. But "water-resistant" and "waterproof while being blasted with road spray for six hours" are different things. Protect your electronics as though they have no water resistance.

For phones, a zip-lock bag is the simplest and most effective protection. You can operate the touch screen through a standard zip-lock bag. For longer-term protection, dedicated waterproof phone cases from brands like Aquapac provide better sealing and lanyard attachment points.

GPS units like the Garmin Edge 1040 Solar and Wahoo ELEMNT ROAM V2 are designed for rain riding, but their charging ports are vulnerable to water intrusion. Dry your charging port thoroughly before connecting a cable, and consider a small rubber port cover for sustained wet riding.

The Anker PowerCore 10000 power bank should live inside a zip-lock bag in your frame bag, along with its charging cable. Keep the cable in a separate small zip-lock to prevent the metal connectors from corroding. Corrosion on USB connectors is the most common rain-related electronics failure, and it is entirely preventable with a 5-cent bag.

Riding in the Rain

Waterproof outerwear is essential for comfort and safety when riding in rain. The Gore Wear ShakeDry Jacket is our top pick—its exposed GORE-TEX membrane sheds water instantly and dries in seconds when the rain stops. Unlike traditional rain jackets with a face fabric, ShakeDry does not wet out, so it remains breathable throughout a long rainy ride.

For your lower body, waterproof shorts or tights are less critical than a good jacket. Most riders simply ride in their normal shorts and accept wet legs—your legs generate enough heat to stay warm, and wet cycling shorts dry quickly during breaks in the rain.

Waterproof socks (from brands like Showers Pass or DexShell) are a worthwhile investment if you ride frequently in wet conditions. Wet feet lead to blisters, numbness, and foot fungus on multi-day trips. Waterproof socks are heavy and expensive compared to regular socks, but the comfort payoff is enormous during all-day rain events.

Fenders are another option for reducing spray. Full-coverage fenders dramatically reduce the amount of water hitting you and your bags from below—the direction most water-resistant bags are least protected against. Lightweight clip-on fenders from Ass Savers or SKS add minimal weight and can be removed when conditions are dry.

Drying Strategies

Wet gear needs to dry. On multi-day trips through wet weather, drying opportunities are precious and should be seized aggressively. Hang wet items inside your tent using clothesline or gear loops. Drape damp clothing over your bike and bags during rest stops. If you get a sunny break, spread everything out immediately—a few minutes of direct sunlight can dry a rain jacket or tent fly remarkably fast.

Body heat drying is surprisingly effective for small items. Damp socks and gloves can be tucked between your base layer and outer layer while you ride. Your body heat will dry them within an hour or two. This technique works for any small, thin item that you can tolerate against your skin.

At camp, change into dry clothing as soon as you stop riding. Keep a complete set of dry camp clothing—base layer, warm mid-layer, dry socks—sealed in a waterproof bag and never wear it while riding. This is your recovery kit, and keeping it dry is non-negotiable. No matter how wet and cold your riding day has been, putting on dry clothes and crawling into a dry sleeping bag resets everything.
