Backpacking Rucksacks

Whether you're planning an overnight wild camp or a week-long mountain expedition, the right waterproof rucksack makes all the difference. This selection features durable backpacking packs engineered for serious outdoor use, from military-style bergens built for heavy loads to lightweight hiking backpacks designed for ultralight adventure.

How to Choose a Backpacking Backpack

Start with trip length and capacity: 35-50L suits overnight trips with minimal gear and sleeping bags. 50-70L handles multi-day mountain travel with full camping equipment. 70L+ covers extended expeditions, winter conditions, and snow camping where you'll carry extra warm clothing and stoves.

Focus on fit and frame type: Measure torso length (not height) to find the right size. Internal frame packs (3-5 lbs) work best for multi-day hiking with balanced loads. External frame options (4-6 lbs) excel at heavy loads using American-style construction. Frameless designs (1-2 lbs) suit ultralight adventure backpackers carrying under 10kg base weight.

Check comfortable load capacity: Military bergens handle 20-30kg (44-66 lbs), when the harness is set correctly. Standard hiking packs manage 15-20kg (33-44 lbs) comfortably. Lightweight options work best under 15kg (33 lbs). Published weight and usable volume matter, ripstop nylon construction and quality zippers ensure durability.

Essential features to search for: Padded waist belt (carries 70-80% of weight), hip belt pockets for easy access, sleeping bag compartment with separate bottom access, rain cover for British weather, compression straps for load balance, and multiple zippered pockets for organization on the trail.

What you get here, and what you do not

• New packs, not graded surplus, so there is no condition lottery and no grading to get wrong
• Real figures, capacity and dimensions wherever the maker supplies them, left out rather than invented where he does not
• Honest weather wording, coated fabric sheds rain but seams and zips are not sealed, so use a liner for anything critical
