A gusset is essentially a liner. It’s where you’ll find our leakproof technology. It’s built into the crotch section of the underwear.

I sized up because I wanted them loose to sleep in - good descison and would recommend. Lower period protection vs dream shorts as shown on site but I must say these are sooo much more comfy compared

I'm loving my comfortable, lightweight modal boxer briefs. Fit is perfect and they stay in place under clothing. Perfect for sleeping too! Some additional colours would be fun.
