Quick answer

Most LBL brief leaks are caused by a poor fit, a change in your flow, or residue buildup from improper washing. Check the gusset position and your wash routine first. If leaks continue, consider whether your absorbency needs have changed.

Check your wash routine first

Residue from fabric softener, dryer sheets, or bleach-based detergents can clog the waterproof layer in LBL briefs, causing liquid to bypass the absorbent core. Wash your briefs in cold or warm water with a mild, fragrance-free detergent and skip the fabric softener entirely. Air-dry only — heat from a dryer can damage the patented sealed seams and reduce absorbency over time.

Verify the gusset position and size

The absorbent panel in LBL briefs must sit directly under the urethra to catch leaks. If the brief is too large, the gusset shifts out of place; if too small, it rides up. Stand in a neutral position and check that the center of the gusset aligns with your body's midline. If it doesn't, try a different size. Love Luna's LBL Midi Briefs use 5 clever layers and sealed seams, so proper positioning is key to their performance.

Know your absorbency limit

Love Luna's LBL Midi Brief absorbs up to 40 ml (about 8 teaspoons). If your leakage exceeds that volume in a single wear, the brief will reach capacity and leak. Track how much you typically leak during your heaviest activity or time of day. If you consistently exceed 40 ml, the brief is not failing — it's simply at its limit. In that case, consider a higher-absorbency product or changing the brief more often.

Diagnosis: Is your LBL brief the problem or the solution?

  • Symptom: Leak occurs at the leg opening or waistband, not at the gusset center. Likely a fit issue — the gusset is not aligned with your body.
  • Cause: The brief is too large or too small, or the gusset shifted during wear. Try a different size or adjust the brief before putting on outer layers.
  • Corrective action: Check gusset position, wash without softener, and air-dry. If leaks persist after two wears with correct positioning, move to the next step. If the brief still leaks, your absorbency need may exceed 40 ml.
  • Stop or choose another option: If you consistently leak more than 40 ml per wear, the brief is at capacity. It is working correctly — you need a higher-absorbency product or a mid-day change. Consider Love Luna's Plus Super Full Brief for heavier needs, or change your LBL Midi Brief more frequently.
