Fit Notes
- For optimal fit, the tie-in points should overlap by 1.5 cm (0.6 in), with the tie-in points and rear rise elastic tab centred on the body.
- The leg loops should sit high on the upper thigh and fit snugly without restricting movement.
- If you can't achieve a proper fit in one size, choose the next size smaller or larger.
- Do not use the Alpha SL if you are outside the size range in the chart, or if your waist is smaller than 67 cm (26.5 in) or larger than 107 cm (42 in).
