When choosing backpack xl size, it’s important to consider both the capacity of your pack and its comfort. Whether you’re carrying heavy school books or travelling with clothes for a week, a pack that’s too large will increase the weight you carry and cause unnecessary stress on your shoulders. On the other hand, a pack that’s too small will force you to bring extra “just in case” items, which can be both inconvenient and expensive.
Luckily, choosing the right backpack size doesn’t have to be difficult. Knack is here to help you find the perfect travel backpack that fits your needs and will allow you to travel light and comfortably.
Knack uses a simple, accurate method to measure backpacks’ capacities. We use the ASTM F2153-07 standard, which requires all fully zipped pockets and compartments to be filled with plastic balls and dumped into a graduated cylinder to determine their volume. This is the most common and reliable way to accurately compare backpack sizing across brands.
In addition to backpack sizing, we’re also careful to provide accurate fit information on our website. Our “Knack & Go” guide will give you an idea of what size backpacks work best for different types of trips and activities. This is especially helpful for first-time backpackers who may be unsure of what size packs they’ll need. We’ll tell you the capacity of each pack, how to properly fit it, and what features you should look for in a good backpack.
