Leakproof Contour Thigh Saver® Control Short Absorption: Light Length: 6"
The Knix Leakproof Contour Thigh Saver Control Short is a high-rise, seamless control short with light absorbency, designed to protect against period leaks, light bladder leakage, sweat, and thigh chafing. It features a silky nylon-blend microfibre with a tummy-firming control panel, a gusset with Fresh Fix Technology, and a 6-inch inseam that reduces thigh friction and helps the short stay in place. User reviews recommend the 6-inch length over shorter versions because it is less likely to ride up, making it ideal for wearing under dresses during events like weddings.

Product Insights
Knix's Leakproof Contour Thigh Saver combines anti-chafe coverage with a light-absorbency gusset for blood, sweat, and urine, while its 6-inch length stays in place under dresses to prevent ride-up. The nylon fabric stays cool and dry on 95°F days, reducing friction and generated heat. A key tradeoff: the high compression slackens after a few wears for a customized fit, so buyers should start with their regular size and not size down. Available in beige and black for discreetness, it offers a risk-free trial—wash and wear within 30 days for a full refund. Care instructions: machine wash cold, no softener, lay flat to dry.

Recommendation for Knix Thigh Saver 6-inch shorts as anti-chafing solution
I like Knix’s “Thigh saver” shorts - they come in a variety of nude colors and are very lightweight. Definitely get the 6” regular ones - I have the 4” too but they tend to ride up a bit.
