Planning a backpacking adventure can be both exciting and overwhelming, especially when it comes to deciding what to pack. With a limited space of a 20-liter backpack, it is crucial to prioritize your items wisely. In this article, we will discuss how to prioritize what to pack for a backpacking adventure using a scientific approach, personal experience, step-by-step process, and examples.

  • Research the climate and terrain: Before packing, it is essential to research the climate and terrain of your destination. For example, if you are traveling to a mountainous region, you will need warm clothing and sturdy footwear. Understanding the local conditions will help you prioritize your packing list accordingly.
  • Make a list of essentials: Start by making a list of essential items that you cannot do without. These may include a tent, sleeping bag, cooking gear, and personal hygiene items. These essentials should be the first priority when packing your backpack.
  • Consider multipurpose items: To save space in your backpack, think about including multipurpose items. For example, a sarong or lightweight towel can serve as a blanket, towel, or a beach cover-up. A multi-tool with a knife, pliers, and screwdriver can replace individual tools.
  • Pack the heaviest items first: When placing items in your backpack, pack the heaviest items first, near your back. This will distribute the weight evenly and provide better balance while hiking. It will also prevent your bag from feeling too top-heavy.
  • Roll clothing instead of folding: Rolling your clothing items instead of folding them can save a significant amount of space in your backpack. It also helps to prevent wrinkles in your clothes. Remember to pack clothing that is suitable for the climate and activities you will be engaging in.
  • Prioritize lightweight and compact gear: Look for lightweight and compact versions of your essential gear. For example, you can opt for a lightweight sleeping bag or a compact stove. Investing in lightweight gear will reduce the overall weight of your backpack and make it easier to carry.
  • Pack versatile clothing: Choose clothing items that can be mixed and matched for different outfits. Opt for clothing made of moisture-wicking and quick-drying materials. This will allow you to pack less clothing and do laundry on the go if needed.
  • Consider the availability of resources at your destination: If you know that certain items will be readily available at your destination, such as toiletries or food, you can prioritize packing other essential items instead. This will save space and reduce the weight of your backpack.
  • Test your packed backpack before your trip: Before embarking on your backpacking adventure, it is advisable to test your packed backpack. Take a short hike or walk with it to ensure that the weight is evenly distributed and that you can comfortably carry it for long durations.

Example: Suppose you are planning a backpacking trip to a warm coastal region. Based on your research, you know that the temperature will be hot during the day and slightly cooler at night. You need to prioritize packing lightweight and moisture-wicking clothing items, a tent, a sleeping bag suitable for warmer temperatures, a compact stove for outdoor cooking, and sunscreen. You can also pack a sarong, which can serve as a beach cover-up, towel, or a picnic blanket.

In conclusion, prioritizing what to pack in a 20-liter backpack for a backpacking adventure requires careful consideration of the climate, terrain, and essential items. By following a systematic approach, considering multipurpose items, packing lightweight and versatile gear, and testing your packed backpack, you can ensure a successful and enjoyable backpacking experience.

Are you ready to embark on a backpacking adventure with a 20-liter backpack? Packing a small backpack can be a challenge, especially if you want to maximize the available space. Don't worry, though, because we have some tips and tricks that will help you make the most of your limited packing space.

  • Roll, don't fold: Instead of folding your clothes, roll them up tightly. Rolling not only saves space but also helps to minimize wrinkles. You can stack and squeeze these rolls into any available nooks and crannies in your backpack.
  • Use packing cubes: Investing in packing cubes can revolutionize your packing game. These lightweight and compartmentalized storage bags can help you keep your belongings organized and compressed. By using packing cubes, you can separate your clothes into different categories and maximize the use of every inch in your backpack.
  • Utilize compression bags: Compression bags are a must-have for anyone packing a small backpack. These bags allow you to squeeze out excess air, effectively compressing your clothes. By reducing the volume of your clothes, you can free up precious space in your backpack.
  • Pack versatile clothing: Choose clothing items that can be mixed and matched to create various outfits. By packing versatile pieces, you can maximize your wardrobe options without sacrificing space. Consider garments made from lightweight and quick-drying fabrics, as they are easier to pack and can be hand-washed if necessary.
  • Bring multi-purpose items: Look for items that can serve multiple purposes. For example, a lightweight scarf can double as a blanket, a sarong, or a headscarf. A travel towel can also be used as a beach towel, a picnic blanket, or a bath towel. Being creative with the use of your belongings can help you pack efficiently and save space.
  • Pack small toiletries: Opt for travel-sized toiletries or transfer your favorite products into smaller containers. Avoid bringing full-size bottles that take up a lot of space. Remember, you can always replenish your supplies during your travels.
  • Wear your bulkiest items: If you have bulky items such as hiking boots or a heavy jacket, wear them while traveling instead of packing them inside your backpack. Wearing your bulkiest clothing items not only saves space but also keeps you warm and comfortable during your journey.
  • Take advantage of pockets and compartments: Utilize every nook and cranny in your backpack. Fill the outer pockets with small items like chargers, snacks, and water bottles. Use the internal compartments to store smaller essentials such as socks, underwear, and electronics. By utilizing these extra spaces, you can free up more room in the main compartment.
  • Consider the weather and destination: Pack accordingly based on the weather conditions and activities at your destination. If you're traveling to a warm and sunny location, you won't need bulky sweaters or heavy jackets. Be mindful of what you truly need and leave unnecessary items behind.
  • Practice minimalism: Finally, the key to maximizing space in a 20-liter backpack is to adopt a minimalist mindset. Take only what you genuinely need and try to avoid bringing non-essential items. Remember, necessities like a passport, money, and a phone are essential, while luxuries can often be left behind.

By following these tips and tricks, you'll be able to make the most of the limited space in your 20-liter backpack. Happy packing and enjoy your backpacking adventure!

When embarking on a backpacking trip, it is crucial to pack efficiently and consider versatile clothing and footwear options. A 20-liter backpack does not allow for a lot of items, so it is important to select items that can serve multiple purposes and still keep you comfortable. In this article, we will discuss some versatile clothing and footwear options for a 20-liter backpacking trip.


  • Moisture-wicking T-shirts: Opt for lightweight, moisture-wicking T-shirts that can be worn for hiking, camping, or even as a base layer under warmer clothing during colder nights.
  • Convertible pants: Look for pants that can be converted into shorts by simply zipping off the lower part. These are great for adapting to changing weather conditions during your trip.
  • Merino wool socks: Merino wool socks offer excellent moisture-wicking properties and are naturally odor-resistant. They can be worn for extended periods without discomfort.
  • Fleece jacket: A lightweight fleece jacket can provide warmth during chilly evenings and can also be used as a layering piece under a rain jacket if needed.


  • Trail running shoes: Trail running shoes are a great option for backpacking trips as they provide comfort, support, and traction on different terrains. Look for shoes that are breathable and quick-drying.
  • Sandals: Consider packing a pair of lightweight sandals that can be used for lounging around camp, creek crossings, or for giving your feet a break after a long day of hiking.
  • Waterproof hiking boots: If you anticipate encountering wet or muddy conditions, it is a good idea to pack a pair of waterproof hiking boots. They offer better ankle support and protection in rough terrains.

Proper layering is crucial when packing for a backpacking trip. By selecting versatile clothing options, you can mix and match to create different outfits suitable for varying weather conditions. Here is an example of how to layer your clothing:

  • Base layer: Start with a moisture-wicking T-shirt as your base layer. This will keep you dry by wicking away sweat.
  • Mid layer: Depending on the weather, you can add a fleece jacket for insulation and extra warmth.
  • Outer layer: A rain jacket or shell should be packed for protection against rain, wind, and to trap body heat.
  • Bottom layer: Convertible pants are ideal for adapting to changing temperatures. You can zip-off the lower part to convert them into shorts when needed.

Remember, the key is to choose clothing made from lightweight, quick-drying materials that can be layered easily. By packing versatile clothing and footwear options, you can ensure that you have the necessary gear to keep you comfortable and prepared for various conditions during your 20-liter backpacking trip.

When packing for a backpacking trip, it's important to prioritize space and weight in order to make the journey more enjoyable and manageable. A 20-liter backpack is a relatively small size, so it's essential to bring only the most crucial items and leave out anything that is not necessary or can be easily obtained during the trip.

Here are some items that you should consider leaving out when packing for a 20-liter backpacking trip:

  • Extra Clothing: It's tempting to pack multiple outfits for various weather conditions, but in reality, you should only bring the bare minimum. Stick to essentials like a lightweight jacket or fleece, a versatile shirt, a pair of long pants, and a pair of shorts. Remember that you can always layer your clothing to adjust to changing temperatures.
  • Unnecessary Electronics: While it's nice to capture memories with a high-quality camera or listen to music with your favorite headphones, these items can be bulky and add unnecessary weight to your backpack. Consider using your smartphone as a multipurpose device instead. Most smartphones have decent cameras and can also function as an MP3 player.
  • Full-Sized Toiletries: Instead of bringing full-sized bottles of shampoo, conditioner, and body wash, opt for travel-sized toiletries or transfer the contents into smaller containers. You can also consider using solid toiletries like shampoo bars and solid deodorants to save space. Remember to bring only the essential toiletries like a toothbrush, toothpaste, and a small towel.
  • Heavy Footwear: It's important to have comfortable and functional footwear for your backpacking trip, but bulky hiking boots can take up a lot of space in your backpack. Unless you're venturing into rough terrains or facing challenging weather conditions, consider opting for lightweight hiking shoes or trail running shoes instead.
  • Excessive Food and Water: While it's crucial to stay hydrated and well-fed during your trip, it's unnecessary to carry excessive amounts of food and water. Research the availability of water sources along your route and plan accordingly. For food, opt for lightweight and nutritious options like dehydrated meals, energy bars, and nuts. Remember that you can restock on food and water along the way if needed.
  • Bulky Sleeping Gear: Sleeping bags and pads can be bulky and take up a lot of space in your backpack. Instead, consider investing in lightweight and compressible sleeping bags and inflatable sleeping pads. These items are specifically designed for backpackers and can significantly save space and weight.

To save even more space and weight, consider packing your backpack strategically. Utilize compression sacks to condense your clothing and sleeping gear. Place heavy items, like your tent or cookware, close to your back to distribute the weight evenly. Finally, always make sure to test your gear before your trip to ensure everything fits and functions properly.

By leaving out unnecessary items and strategically packing your backpack, you can optimize space and weight for a more enjoyable and comfortable backpacking trip. Remember that each journey is unique, so it's essential to evaluate your needs based on the specific conditions and duration of your trip.
