How to choose a second-hand tramping pack

A good second-hand pack needs to fit you, hold your trip’s gear and still have sound working parts. The litre number is useful, but it won’t tell you whether the harness sits properly or the base is wearing through.

Litres, torso size and harness terms

• Capacity in litres: The amount of storage space. A 60 L pack carries more volume than a 30 L pack; the number is not a kilogram load limit.
• Torso size: The length of back the harness is designed to fit. Measure from the prominent bone at the base of your neck to the level of the top of your hip bones.
• Hip belt: Transfers much of the load onto your hips. Its padding should wrap your hip bones comfortably.
• Load lifters: Small straps from the upper shoulder straps to the pack. They draw the load closer for stability.
• Sternum strap: The chest strap joining the shoulder straps. Adjust it to stabilise them without restricting breathing.

How to choose: lay out your complete kit first, then try a pack that fits it with the expected load. A larger capacity does not fix a harness that is too long or a hip belt that will not tighten.

Start with the actual size and model

Ask for a clear photo of the size label and the exact model, including any torso-size or harness marking. Compare it with the manufacturer’s information for that version. Don’t assume two packs with the same capacity have the same fit.

Osprey publishes pack sizing guidance, but the correct reference is the one that applies to the pack you’re considering. If the label is missing or the model is uncertain, treat the fit information as uncertain too.

Inspect the places that take the load

Look closely at the shoulder-strap attachments, hip belt, haul loop, base and main seams. Ask for close photos of wear rather than relying on one front-on image.

• Check for torn fabric, separating seams and badly worn webbing.
• Look inside for peeling or sticky coatings and ask about persistent odours.
• Check the frame and stays for damage or missing pieces.
• Operate every buckle and zip, including pockets you expect to use.

A worn finish and a failing load-bearing seam are different buying decisions. If a structural repair is needed, get the repair assessed and priced before committing.

Try it with a realistic load

When a try-on is possible, use a representative load and adjust the pack according to its instructions. Walk around, reach for the pockets and check that adjustments stay in place. An empty pack can feel fine while telling you little about loaded comfort.

For an online purchase, ask for the measurements and evidence you need, and read the return terms before buying. A height-based guess is a weak substitute for a confirmed fit.

Count the included parts and total cost

Confirm whether the lid, rain cover, detachable straps or other model-specific parts are included. Photos of a complete new model don’t prove the used one has them.

Add repair, cleaning, replacement parts and delivery to the asking price. Then compare the whole cost with other suitable packs. Use our condition-grade guide alongside the actual listing photos and faults. A grade is a starting point, not a replacement for those details.
