ROOT8 vs ROOT18: How Much Capacity Do You Really Need?

ROOT8 vs ROOT18 comes down to how much the route asks you to carry. An 18L pack is not automatically better, and an 8L pack is not always enough. Start with the longest unsupported section and the gear you cannot leave behind.

ROOT8 for daily training and medium loads

The LECAMO ROOT8 8L trail running pack is the current middle option in the LECAMO carry system. It suits daily training and mid-distance routes where you need hydration, food, a layer and other essentials without a full day-hiking load.

ROOT18 for longer routes and more mandatory gear

The LECAMO ROOT18 18L trail running and fast-hiking pack is for longer routes, more mandatory equipment or fast day-hiking scenarios. It gives you room when the route includes extra layers, food, water and equipment that cannot be compressed into a smaller carry list.

Use this capacity check

1. Mark the longest section without a dependable refill.
2. List water, food, warmth, navigation and mandatory equipment for that section.
3. Add only items you have a real reason to carry.
4. Load the pack and rehearse drinking, eating and adding a layer without unpacking everything.

When ROOT18 is too much

If your normal route is supported and your list stays small, unused space can encourage overpacking. Choose ROOT8 when it covers the plan cleanly. Capacity should follow the route, not the other way around.

Compare your next route with each pack

Check the ROOT8 8L product details for your daily carry list, or the ROOT18 18L product details when you need a larger single-day load.
