Top Y25D Maternity Biker Shorts & Seamless Underwear for Pregnancy Comfort in 2026
Introduction
Pregnancy brings a long list of physical changes, and finding clothing that actually fits comfortably—without digging in, rolling down, or leaving you constantly adjusting—can feel like a second job. Maternity wear needs to stretch with your growing belly, support your lower back, and stay put through daily activities from walking to working to resting. The wrong pair of shorts or underwear can turn a simple errand into an exercise in frustration. This guide focuses on two standout options from the Y25D brand that address these exact problems: a set of maternity biker shorts with pockets and a pack of seamless high-waisted maternity underwear. Both are designed for the over-belly fit that many expecting mothers prefer, and both have earned strong early ratings from real buyers.
What to Look For in Maternity Shorts and Underwear
When evaluating maternity bottoms for pregnancy, keep these criteria in mind:
- Over-belly coverage: The fabric should rise comfortably above your bump without tight elastic bands pressing into your abdomen. A high-waisted or over-belly design distributes support evenly.
- Seamless construction: Seams that rub against sensitive skin can cause irritation, especially as your body changes. Seamless or flat-seam options reduce chafing.
- Stretch and recovery: The material should stretch to accommodate your growing belly and then return to shape without sagging. Look for four-way stretch fabrics.
- Breathability: Pregnancy raises your core temperature. Moisture-wicking, breathable fabrics help you stay cool during exercise or warm weather.
- Pocket functionality: If you need to carry a phone, keys, or cards while walking or running, secure pockets are a major convenience—especially when you don’t want to carry a bag.
- Fit consistency across sizes: Maternity bodies change week to week. A product that fits well in one trimester should still work in the next, assuming you choose the correct size.
- Value for a multi-pack: Pregnancy is temporary, so buying a set of shorts or underwear in a bundle often makes more sense than purchasing single high-priced items.

Buying Tips
- Check the sizing chart carefully before ordering. Both products are listed in size Medium for these specific bundles. If you are between sizes or in your third trimester, measure your current belly circumference and compare it to the brand’s size guide on the product page.
- Consider buying both sets for a complete maternity wardrobe. The shorts work for exercise and casual wear, while the underwear is designed for daily layering. Together, they cover most of your bottom-half needs.
- Wash before first wear. Like most seamless activewear and underwear, these items benefit from a gentle wash cycle to remove any manufacturing residues and to help the fabric settle.
- Rotate between pairs to extend lifespan. With three pairs in each pack, you can alternate wears and washes, which helps maintain the elastic recovery of the fabric over time.
- Read recent reviews for fit updates. Since bodies change during pregnancy, look for reviews from women at a similar stage to yours. The underwear has over 400 reviews, so you can find feedback from various trimesters.
FAQ

A: The over-belly design and seamless construction help the shorts stay put during movement. Early reviews suggest good staying power, but individual results depend on your body shape and activity level.

A: Yes. The seamless edges are designed to be invisible under tight clothing, making them a good choice for layering under leggings, yoga pants, or fitted dresses.

Final Recommendation
If you are looking for comfortable, functional maternity bottoms that support your bump without constant adjusting, both Y25D products deliver solid value at an accessible price point.
