What makes them different

Designed to fix what you never liked about seamless

01

Stay-Put Fit

Fuller back coverage and bonded edges mean they stay in place — no riding up, no wedgies, no constant adjusting.

02

Minimal Lines

Bonded edges lie flat against your skin for softer lines than regular seams — no harsh ridges, digging, or rolling hems.

03

Silky Breathable Fabric

Premium recycled nylon that feels silky, not plasticky, with a cotton gusset where it matters for breathability.

04

Better Price

Premium materials and tested durability at a fair price. No markup for marketing — just better undies you can wear daily.

Common Questions

We recommend going with your usual underwear size. If you're between sizes, we found that it is best to size up. Our size guide has exact measurements — and if you're still unsure, email us at hello@properbasics.com.

That's exactly the problem we designed them to solve. Fuller back coverage and bonded edges create a stay-put fit that doesn't creep, bunch, or need adjusting through the day.

We wash-test every batch. Machine wash cold and tumble dry low — they keep their shape, softness, and stretch.

We accept returns for store credit within 30 days. To qualify, items must be unworn with tags attached. While undergarments are usually final sale, we try to make buying online easier for you. Read our Return Policy for more information.

Bonded edges lie much flatter than traditional seams, so visible lines are minimal under most fabrics. They're not 100% invisible under very thin or super tight bottoms (we'd rather be honest), but under everyday clothes they disappear.
