How to Measure
In order to select the correct sizing, we recommend you take the following measurements using a soft tape measure. If necessary, ask someone else to help.
Waist
Measure around the narrowest part of your torso, usually just above your belly button. Keep the tape snug and level, but not tight. The number where it meets is your waist measurement.
Hip
Stand with your feet together and measure around the fullest part of your hips and buttocks. Keep the tape level and snug, but not tight. The number where it meets is your hip measurement.

How to wash
Knix underwear is 100% reusable and machine washable, just like your regular undies.
Not required. But for best results, you can rinse your leakproof with cold water in the tub or sink before washing.
Machine wash on a cold, gentle cycle with mild detergent.
For their longest life, air drying is best. Hang or lay flat to dry.
Fabric softeners, bleach, ironing, or heat from the dryer.
Reviews Summary
Generated by AI from 100 most recent customer reviews
Last updated 5 months ago
Customers say these boyshorts are exceptionally comfortable with soft, smooth fabric that feels invisible under clothing. Many reviews mention the no-show design eliminates visible panty lines, making them ideal for tight-fitting clothes. Users appreciate the true-to-size fit and coverage that doesn't ride up or roll down. However, durability concerns emerge frequently, with several customers noting seams separating and binding coming apart after just a few washes. Many longtime customers express disappointment about reduced color options, requesting more variety beyond the current neutral tones. While most praise the comfort and fit, some mention sizing issues and wish for better longevity given the price point.

- Rated 5 out of 5 stars3 minutes agoMy Underwear Must-have
I’ve been ordering Knix for years—same style, different leak levels, always perfect . They last and last—just wash and dry in the zipper bag (although I do give my soiled pairs a good rinse in cold water before laundering). To illustrate how they hold up over time, I typically order 12 pair at a go which last around two years with daily wear—they could go longer if needed, but hey, new undies are nice to have!
I’ve noticed some slight changes to their products over time, a real testament to their ability to meet customer needs and improve their product. For example, seams are reinforced at the gusset now, something that was missing early on and which caused items to wear faster. It also seemed that the absorbability and length of the gussets (on the leakproof versions) improved with each order. All of this raised Knix from a solid 4.6 to a full 5 stars in my book.
Since I’m apparently toward the end of perimenopause and not having regular cycles anymore, I’ve opted for the standard version this time and have once again been very pleased. The material feels super delicate and stretchy, but I know that I can count on it holding its shape over time. They always start out a bit snug but are sure to conform to a buttery custom fit within a few wash-and-wear cycles.
Knix is one of the most consistent companies out there, and for me, their products and customer service have stood the test of time.

Comfortable, but seems to ride up a bit, unlike the leakproof ones of the same size.
Perfect fit at the beginning, but then they stretch out- not badly, just not tight anymore.

I don't order a bra on line but decided to give it a try. Bra fits good and so does the panties. Just placed another order.

She says most comfortable underwear she has ever worn.
EHEva H.Verified BuyerReviewingEssential No-Show Boyshort Warm Sand / S - Rated 5 out of 5 stars4 months agoFinally, butt coverage…
…and a gusset that reaches far enough up the front! We ladies need protection toward the front too, but I guess makers are men who only think about their backside. I’m so tired of gussets not reaching far enough in the front and just having a 1-ply where you need it most!
And like I said—bum coverage for the non-twig female so no more wedgies.
Please give us more colors in this style!!
