Packing Smart for the Outdoors
Getting your pack weight right is one of the most important aspects of any outdoor trip. An overloaded rucksack makes every hill harder and every mile longer, while forgetting essential gear can put you at risk. Our packing and gear calculators help you strike the right balance between comfort and safety.
The general rule for backpacking is to keep your base weight (everything except consumables and worn items) under 10kg for lightweight hiking, or under 5kg for ultralight. Our pack weight calculator breaks down your load into these categories so you can see exactly where the weight is going.
Sleeping bag temperature ratings follow the EN 13537 / ISO 23537 standard, which gives comfort, lower limit and extreme ratings. Our sleeping bag temperature calculator helps you choose the right rating based on expected conditions, altitude and whether you sleep warm or cold.
