Find the right weight of rucksack for every camping or hiking trip. A loaded pack should not be more than 20 percent of your body weight. Here is a good rule to follow For hikers and travellers, a comfortable range usually is between 20 and 30 percent of body weight.
Too heavy a load brings tirednes, back pain and even long term injuries.
How Heavy Should Your Rucksack Be
For new backpackers, that is around 20 to 30 pounds. Season, terrain and goals change the rucksack. Climate, year, water and landscape, all change the weight.
Traditional rucksack usually has base weight of at least 20 pounds, without food or water. Perfect for weekend trips or some miles to a near camp. Expert hikers reach 5 to 10 pounds basic, using only things they need without losing comfort.
Ultralight-bags weigh base 8 to 10 pounds, full 15 to 20. In ultralight-world, under 10 pounds is the limit.
Summer base sits around 13 pounds. Shoulder season reaches 16 to 17 pounds. Starting weight is low to mid 20s for 3-4 days, or even 30 pounds with water.
Quick trip: around 12 pounds. For five day haul: around 20 pounds.
Under 30 pounds is possible with a bit of work, maybe under 20 with fancy ultralight and cutting surplus. 40 pounds in winter beats almost all. 15 against 20 pounds does knot always matter however.
Lay heavy stuff up, for equal weight on chest, not on lower back. Waist belt bears most to hips. Well fitted rucksack loads pelvis and legs, not back or shoulders.
Short trips use heavy traditional, they are comfortable, easy to fit and versatile. Less weight equals more fun in backpackingworld.
