Pump carry: fit is a system, not a size
The pump, tubing, clothing, activity, access needs, and body measurements all affect whether a belt or pouch works.
What to compare
Exact pump
Confirm dimensions, controls, tubing position, and manufacturer compatibility.
Access
Decide whether viewing and operating the pump without removal is essential.
Body and clothing
Measure where the item will sit and test with realistic clothing.
Movement
Check bounce, rotation, pressure, and tubing under daily activity.
Care
Review seams, closures, washing, drying, and replacement expectations.
