Torso and hipbelt fit
Use the brand's measurement guide and the exact size or Extended Fit range. Height alone is not a reliable pack-size selector.

Backpacks buying advice
Before you buy
Try your expected load
Test the loaded pack in store where possible. Check hipbelt contact, shoulder movement and access to pockets, not just the empty weight.
Protect what must stay dry
Check whether a raincover is included and how the manufacturer describes water resistance. Do not assume a raincover makes the contents waterproof.
From first use to the next trip
Use, care & repair
01Measure before adjusting
Follow the brand's torso and hipbelt sizing instructions, then adjust the harness with a realistic load.
02Check the complete packing list
Allow room for water, food, layers and emergency equipment. Try opening and closing the pack with everything inside before leaving.
03Clean and inspect
Use the model's cleaning instructions. Inspect seams, straps and buckles, and dry thoroughly before storing.

Macpac hiking-backpack fitting guideScope & source notes
General manufacturer guidance on torso measurement and hiking-pack adjustment, not a verified fit range for an exact pack. Apply only adjustments present on your harness; it is not a child-carrier, running-vest or pack-accessory manual. The original model instructions and sizing information take precedence.
Common buying questions
Good to know
Should I choose pack size from my height?
Use torso length and the hipbelt fit range first. Two people of the same height can need different harness sizes.
Does more capacity mean a better pack?
Only if you need that space and the load stays within the manufacturer's guidance. Fit, carry system and access can matter more than a few extra litres.
Is a raincover enough to protect my sleeping bag?
Check the cover and pack limitations. Keep essential dry items in appropriate waterproof protection rather than relying on a cover alone.
