What to Compare Before Buying
- Check that your phone fits the front pocket, particularly if it is larger than the stated iPhone 17 Pro Max reference.
- Confirm that your soft flask is no larger than the stated 500 ml capacity.
- Consider what you plan to carry across the four storage areas, including whether the side pockets suit your small essentials.
Compatibility, Size and Fit
The belt is described for men and women and for daily training, race efforts and light trail runs. It has some compression, so sizing up one size is recommended for a better wearing experience. Check the selected size and the fit of your intended phone, flask and folding poles before use.
Before You Decide
Confirm the belt size, phone fit and flask capacity for your setup. If you plan to carry folding trekking poles, check that they suit the rear elastic straps.
