Backpack vs weight vest
Backpack or weight vest for rucking? How to choose something stable, safe and beginner-friendly.
You can ruck with either. They just do not load you the same way, and the difference matters most if you have a back or a pair of shoulders that need consideration.
The short version
If you already own a backpack, start with that. It costs nothing, you can adjust the load with things you already have, and you find out whether rucking suits you before spending money.
A weight vest is worth considering if the pack chafes, if you want the load closer to your centre of mass, or if you will use the vest for other training too.
How they load you differently
A backpack puts the weight behind your line of gravity. That pulls you backwards, and the body compensates by leaning the torso forward. The lower the weight sits, the more you lean.
A vest spreads the load around the torso, front and back. That keeps your centre of mass closer to where it normally is, so less compensation is needed.
The literature is not unanimous, though. A 2022 review found mixed results for where on the back the load should sit: at 15% of body weight it could not measure a clear difference between high, medium and low placement. So treat "high and close" as a sensible default rather than proven fact.
When the vest is the right call
If you feel the pack in your lower back rather than in your legs, that is often a sign you are leaning forward to balance it. A vest can remove exactly that.
If you have broad shoulders or a short back and can never get a pack to sit without chafing, a vest often solves it, because the load does not rest on two straps.
If you combine walks with other training, a vest works for both. A backpack only works for walking.
When the backpack is the right call
When you are new. There is no reason to buy gear for a habit you do not have yet.
When you need to carry things. Water, a jacket, food and a phone have to go somewhere, and a vest has no room.
When you want fine control over the load. Water bottles can be emptied mid-walk if the route turns out to be too much - weight plates in a vest cannot.
Whichever you choose
The load must sit stable and not bounce with each step. If it bounces, the load arrives as impacts rather than as steady weight.
No hard edges directly against your back. Pack around plates, or use something soft.
Tighten the hip belt and chest strap if there is one. That moves weight from shoulders to hips, which are built to carry.
- Stable before heavy
- A backpack is fine to start
- Weight high and close
- No sharp edges

- Impact of Backpacks on Ergonomics: Biomechanical and Physiological Effects: A Narrative Review — Genitrini, Dotti, Bianca & Ferri, International Journal of Environmental Research and Public Health, 2022. Finds mixed results for load placement on the back, and recommends generally not exceeding 40% of body weight for healthy adults.
