A 16 kg backpack before adding water can spoil even a well-planned route. Shoulder pain, a slower pace, and reluctance to cover more kilometers are usually not the result of poor fitness, but of gear chosen without weight control. Ultralight backpacking is not about sacrificing safety or buying the most expensive gear. It is a way of assembling a kit where every item has a specific purpose and its weight is justified.
For one hiker, an ultralight kit will mean a 6-7 kg base weight for a summer trek in the Beskid Mountains. For another, it might be 9 kg for a multi-day route with cold nights, rain, and sections without reliable access to water. The numbers are helpful, but the trip scenario is more important: season, forecast, route length, the possibility of buying food along the way, and the participants' experience.
Ultralight backpacking begins with base weight
Base weight is the weight of all the equipment carried in the backpack, excluding food, water, and fuel. This includes the tent, sleeping bag, sleeping pad, backpack, spare clothing, cooking gear, electronics, and first aid kit. Things worn on the body are not included, but it is not worth artificially improving the result by stuffing a heavy jacket or a knife into your pockets. The goal is a comfortable and safe hike, not a record on a chart.
Most of the weight usually comes from four categories: the transport system, shelter, sleep system, and food/water. Before you swap a spoon for a titanium one or cut the tag off your t-shirt, check these exact elements. Replacing a heavy, 75-liter backpack with a model suited to the actual volume of your gear can have a greater effect than a dozen small purchases.
Light does not mean minimal. If you are hiking in the mountains in autumn, a warm insulating layer, a full first aid kit, and an effective rain jacket are essential equipment. Skimping on protection against hypothermia or navigation is not ultralight backpacking; it is unnecessary risk.
Start with what you already have
The most practical method is to spread your current kit out on the floor and weigh each item. All you need is a standard kitchen scale and a note on your phone. Record not just the weight of the product, but also the stuff sack, batteries, cords, stakes, and packaging. It is precisely these extras that often make the manufacturer's stated weight irrelevant.
For every item, ask yourself three questions: do I use it every day, does it serve an emergency function, and does other equipment already fulfill the same task? A second mug, a separate plate, and a large knife might be useful at a family campsite, but during a solo hike, they usually duplicate the use of your pot, spoon, and multitool. On the other hand, a headlamp, water filter, or thermal blanket weigh very little but solve real problems in the field.
Do not remove emergency gear just because you use it rarely. A first aid kit, a light source, a moisture-proof lighter, offline maps, and a basic repair kit should remain in your pack. However, their contents should be adjusted to the specific route, rather than packing the same "all-purpose" kit for every overnight trip.
An ultralight backpack must fit the load
Buy your backpack after assembling the main components, not the other way around. Once you have your tent or tarp, sleeping bag, pad, and cooking set, it is easier to determine the capacity you need. For summer trips with light gear, 35-45 liters is often enough. Multi-day expeditions, colder months, or the need to carry a larger supply of water may require 50-60 liters.
Low backpack weight must not mean poor load-bearing. With a total weight of about 10-12 kg, a minimalist model without an elaborate frame can be comfortable. If you regularly carry more, choose a design with a hip belt and a carrying system that transfers the weight from your shoulders to your hips. Try on the backpack with a load similar to what you will take on the trail.
Pack soft items against your back, heavier items close to the center and as high as possible, and gear needed during the day on top or in pockets. Your rain jacket, filter, snacks, map, and headlamp should not require unpacking the entire main compartment. Well-organized luggage reduces the number of stops and helps maintain order even in the rain.
Sleeping without extra kilograms
Treat your sleep system as a whole. A tent, tarp, or hammock, sleeping bag or quilt, sleeping pad, and sleep clothing must match the conditions, not just look light in the product description. In the Polish mountains, a summer night after a thunderstorm can be significantly colder than the forecast for a nearby town suggests.
A one-person tent is a reasonable choice for a solo hiker who needs protection from rain, wind, and insects. A tarp reduces weight but requires skill to set up and a good choice of campsite. A hammock works well where there are trees and where the user can protect themselves from cold from below. It is not a universal solution for every route.
For a sleeping bag, pay attention to the comfort temperature, not just the limit value. Down offers an excellent warmth-to-weight and volume ratio but requires protection from moisture. Synthetic will usually be heavier but handles damp conditions better and is easier to dry. A sleeping pad is not an accessory—its insulation from the cold ground often determines the quality of your sleep more than an extra sweatshirt.
Water, cooking, and food on the trail
Water is the heaviest part of the kit, as a liter weighs a kilogram. This does not mean you should take too little. Before you leave, check the location of springs, mountain huts, streams, and any restrictions on the route. Where water access is regular, a practical hiking filter or purification tablets allow you to carry a smaller supply. In uncertain places, you must have a backup supply and an emergency plan.
An ultralight kitchen should match your menu. If you eat no-cook products for two days, a stove and pot may be unnecessary. If you plan on freeze-dried meals, coffee, and hot food, a simple gas stove, canister, lightweight pot, and lighter will make a functional set. On a longer route, also assess fuel consumption and the possibility of buying a canister along the way.
Choose food with a high energy-to-weight ratio: nuts, dried fruit, peanut butter, energy bars, instant porridge, freeze-dried meals, and powdered products. Repacking portions into lightweight, airtight bags reduces volume and waste. However, do not pack just the bare minimum of food. Delays, changes in weather, or increased physical effort quickly raise your energy requirements.
Layered clothing instead of a set for every day
A heavy backpack is often the result of packing a full set of clothes for every day. For trekking, a layered system works better: a moisture-wicking base layer, an insulating layer, and a jacket that protects against wind and rain. In addition, you need a dry set for sleeping, spare underwear, socks, and a hat suited to the temperature.
Material matters, but the ability to use one item in several situations is even more important. A light fleece sweatshirt can be used while hiking and during breaks, and a rain jacket also shields you from strong wind. In the cold, a separate insulating jacket is useful because stopping your hike immediately changes your perceived temperature.
Protect all water-sensitive items in waterproof bags or sturdy dry sacks. This especially applies to your sleeping bag, electronics, spare clothing, and documents. A rain cover for your backpack helps, but it does not replace protecting the contents during hours of heavy rain.
Where not to cut weight
There are elements that should be reduced with caution. These include footwear, sleep insulation, rain protection, a first aid kit, lighting, and communication or navigation devices. Lightweight shoes can be great for an easy trail with a light load, but they may not provide stability to everyone on wet, rocky terrain. The choice depends on the condition of your joints, your walking technique, and the weight of your pack.
The same applies to electronics. One phone with offline maps, a power bank matched to the length of the route, and a headlamp are usually more practical than separate devices for every task. Do not, however, give up on power just to lower the weight by a few hundred grams. A dead phone after dark in bad weather comes at a much higher price than the extra weight.
When assembling your kit, compare parameters by usage: backpack capacity, sleeping bag comfort temperature, sleeping pad R-value, filter efficiency, headlamp runtime, and the actual total weight of the entire kit. At BeOnWin, it is easier to organize such purchases by equipment category rather than picking random items separately.
For your first light hike, do not change everything at once. Take your current, reasonably lightened kit on a day hike or an overnight trip close to the starting point. Upon returning, immediately write down what you didn't use, what you lacked, and what hindered your packing. It is your own experience that allows you to shed more grams without depriving yourself of comfort and safety.
