Ready for your next adventure? Getting your gear right is the first step. A duffel bag is a versatile workhorse, perfect for hauling everything you need, but choosing the wrong size can weigh you down or leave essential items behind.
This duffel bag size guide will help you select the best travel duffel bag, whether you need a compact carry-on or a heavy-duty expedition hauler. Let's find the perfect fit for your trip.
Common duffel sizes and their uses
Duffel bags are measured in liters (L) to indicate their volume. Understanding these common sizes helps you match the bag to your adventure. From a small duffel bag for daily use to an extra-large duffel bag for major expeditions, there’s a size for every need.
Small (Under ~30 L)
A small duffel is perfect for outdoor day trips, carrying trailhead gear, or for minimalist packers. Their portability makes them easy to stash in a kayak, toss in the back of a car, or use as a compact overnight bag. A 30L duffel bag, like the versatile Canyon Duffel Pack 35L, is the ideal lightweight gear bag for storing essentials like base layers, a rain jacket, snacks, and footwear.
Medium (30–60 L)
The medium duffel bag is the sweet spot for weekend trips to the mountains, overnight sailing, or backcountry stays. A 50L duffel like the H/H Scout Duffel M offers enough space for a few changes of technical clothing and outdoor essentials while remaining easy to carry on your shoulders or as a backpack. This size is the ultimate weekend outdoor duffel or medium expedition bag.
Large (60–90 L)
Large duffel bags are ideal for weeklong outdoor travel, ski trips, or expeditions where bulky outerwear and multiple gear layers are non-negotiable. A 70L duffel, such as the Canyon Duffel Pack 65L, is a rugged, weather-resistant expedition gear bag designed for tough outdoor conditions. Just be mindful of the weight when this large waterproof duffel is fully packed.
Extra-large (90+ L)
When you need to haul serious expedition gear, you need an extra-large duffel bag. Perfect for extended sailing voyages or mountaineering trips requiring ropes, helmets, and heavy outerwear layers, a 100L+ duffel is built tough. Bags like the Start Hytte 140L Bag are true gear-hauling bags, designed to withstand rough handling and harsh outdoor elements.
Size considerations by trip type
Your adventure dictates your gear. Whether it’s a quick gym session or a month-long trek, the trip length and activity type are key factors in choosing your duffel. Find the best gym duffel bag for your workouts or the best camping duffel bag for your wilderness escapes.
Daily use
Compact duffels between 20–35 L are your go-to for daily missions. They provide grab-and-go convenience for carrying climbing shoes to the crag, dry clothes for after-skiing, or gear for a quick paddle. A small outdoor duffel is the ultimate adventure day bag.
Weekend getaways
For 2–3 days in the mountains or on the coast, a 40–60 L duffel has you covered. This mid-size gear bag easily handles clothing, midlayers, and essential outdoor gear. Its versatility makes it the perfect weekend outdoor duffel for car trips, boat storage, or camping weekends.
Multi-day / 1–2 weeks
A 60–90 L duffel shines for extended outdoor adventures. It’s the ideal 7-day expedition duffel for weeklong sailing trips, ski vacations, or backcountry expeditions. It has the capacity for boots, outer shells, and technical layers while still being transportable, making it an excellent weeklong gear bag.
Extended travel or gear-heavy trips
When hauling climbing gear or equipment for an extended expedition, you need a 90+ L expedition duffel bag. These oversized outdoor duffels are designed to be a primary gear hauler. For easier carrying, some adventurers prefer to split their equipment between two medium duffel bags.
Features that affect size choice
Beyond volume, certain features can influence which durable duffel bag you choose. Elements like compression straps and packability can make a significant difference in how you pack and travel.
Compression straps, expandable compartments
Features like compression straps are invaluable on mountain or sailing trips when gear can shift inside your bag. An expandable outdoor duffel with separate compartments allows you to stow wet or dirty gear away from your clean clothes. The Canyon Duffel Pack 50L is a great example of a gear bag designed for adaptable packing.
Packability & storage when empty
A packable outdoor duffel that stuffs into its own pouch is incredibly useful on expeditions where you might need extra gear bags for the return journey. This foldable expedition bag offers flexibility that more rigid duffels don't. A lightweight backup duffel is always a smart addition to your gear list.
How to pick the right size for you
Ready to choose your outdoor duffel size? Match your bag to your adventure. Consider your trip length, the climate (bulky cold-weather gear versus light summer layers), and your mode of transport. An expedition bag guide can point you in the right direction, but ultimately, the choice is yours.
