Rata 40 Fit Guide
The Rata 40 comes in three back lengths - the volume stays the same across all three sizes, only the harness geometry changes. To find your size, you need to measure your torso length.
How to measure your torso length
You'll need a flexible tape measure and a friend.
- Tilt your head forward slightly and find the bony bump at the base of your neck where it meets your shoulders. This is your C7 vertebra - your top measurement point.
- Run your hands down your sides from your ribcage until you feel the top of your hip bones - the firm shelf that your hands naturally rest on. This is your iliac crest. Draw an imaginary line across your back connecting the top of both hip bones - where this crosses your spine is your bottom measurement point.
- Stand up straight and have your friend measure from your C7 down to that point along your spine.
Take your time getting this right - the Rata 40 is made to order and custom sized packs can't be resized after the fact. If you are unsure about your measurements, get in touch before ordering.
Torso size chart
| Size | Torso length |
|---|---|
| Small | Up to 420mm |
| Medium | 420mm - 470mm |
| Large | 470mm - 520mm |
If you are between sizes, size up. If your torso length is outside this range, get in touch - custom back lengths are available on request.
Hip belt sizing
The padded hip belt comes in three sizes. The size refers to the length of the padded section - every hip belt also has enough webbing adjustment to accommodate an additional 50cm of hip circumference beyond the recommended range if needed.
How to measure your hip size
Wrap a tape measure around your hip bones at the point where you would normally wear a hip belt. Note the measurement and refer to the chart below.
| Size | Padded section | Hip circumference |
|---|---|---|
| Small | 650mm | 80cm - 95cm |
| Medium | 700mm | 85cm - 100cm |
| Large | 750mm | 90cm - 105cm |
If you are outside these ranges the webbing adjustment may still accommodate you - get in touch and I can help. Custom sizes are available on request.
Note: the simple webbing hip belt is one size and adjusts to fit most hip sizes.
