|---|---|---|---|
| 27 | 34.3 | 45.1 | 15 |
| 30 | 38 | 48.5 | 16.5 |

Product questions
Are the Betty Biker jeans waterproof?
No. John Doe describes them as water repellent and breathable, but does not publish a waterproof membrane or waterproof rating.
What fit do they have?
The Betty Biker has a high-waist slim fit with a slim leg. Stretch denim and flexible panels support movement, but the cut remains close fitting.
Can the knee armour be repositioned?
Yes. The integrated knee protector pockets are height adjustable so the supplied protectors can be positioned over the knees.
