Finding comfortable clothing during pregnancy is a challenge that every expecting mother knows well. The wrong fit can mean constant tugging, rolling waistbands, or pressure on your growing belly. After reviewing the Y25D lineup of maternity essentials, we’ve identified two products that stand out for their thoughtful design and practical features. This guide focuses on a biker shorts set and a seamless underwear set that work together to provide the support you need without sacrificing comfort or style.

What I Like

The combination of these two Y25D products creates a solid foundation for any maternity wardrobe. Starting with the biker shorts: the seamless construction is a genuine relief for sensitive skin. During pregnancy, even small seams can become irritating, and the absence of them here makes a noticeable difference. The over-belly waistband stays put without digging in, which is exactly what you want when you’re bending, walking, or sitting for extended periods.

The pockets on the biker shorts are a practical touch that many maternity shorts overlook. Being able to carry your phone while walking the dog or running errands without needing a bag is genuinely convenient. The 8-inch inseam hits a good middle ground—long enough to prevent riding up during activity, short enough to stay cool in warmer weather.

The matching underwear set complements the shorts perfectly. The seamless high-waisted design means no visible lines under the shorts, and the over-bump cut provides consistent coverage. The fabric has a soft, stretchy feel that moves with you rather than against you. With 407 reviews and a 4.6-star average, this underwear set has clearly worked well for many expecting mothers.

Both products are machine washable and hold up well to regular wear. The three-pack format for each set gives you options for mixing and matching, which is helpful when laundry days feel further apart than they used to.

Honest Caveats

No product is perfect, and it’s important to be transparent about limitations. The biker shorts set currently has only 10 reviews, which means the 4.9 rating is based on a small sample size. While the initial feedback is excellent, it’s worth noting that long-term durability data is limited at this stage.

The sizing runs consistent with typical maternity wear, but if you are between sizes, you may want to consider sizing up—especially in the biker shorts, as the over-belly band needs to accommodate growth throughout your pregnancy. The medium size in this review worked for a standard second-trimester build, but your experience may vary depending on your body shape and how your belly carries.

The underwear set, while highly rated, uses a seamless construction that may feel slightly less supportive than traditional cotton maternity underwear for some users. If you prefer a more structured fit, this might feel too lightweight. Additionally, the nude color options are limited to two shades in the three-pack, which may not match all skin tones perfectly.

Neither product is designed for high-intensity workouts or swimming. The biker shorts are best suited for walking, yoga, lounging, and light activity. For running or gym sessions, you may want to look for compression-specific maternity gear.

Who It’s For / Who It’s NOT For

Who It’s For

• Expecting mothers in their second and third trimesters – The over-belly designs accommodate a growing bump comfortably
• Moms who value convenience – Pockets on the shorts and the three-pack format reduce daily friction
• Those with sensitive skin – Seamless construction minimizes irritation
• Budget-conscious shoppers – At approximately $19.99 per three-pack, both sets offer good value
• Moms looking for layering pieces – These work well under dresses, tunics, or loose tops

Who It’s NOT For

• First-trimester shoppers – The over-belly waistbands may feel too high or loose early in pregnancy
• Those needing heavy compression – These are support garments, not medical-grade compression wear
• Athletes doing high-impact exercise – The shorts lack the compression and moisture-wicking features of performance gear
• Anyone who prefers full-coverage cotton underwear – The seamless fabric is a synthetic blend, not cotton
• Shoppers wanting a single color option – Both sets come in multi-packs with specific color combinations

Verdict

The Y25D Maternity Biker Shorts with Pockets and the Y25D Maternity Underwear Seamless High Waisted Over Bump are a practical, well-designed combination for expecting mothers who prioritize comfort and convenience. The biker shorts offer a rare pocket feature that genuinely improves daily life, while the underwear provides reliable, invisible support under any outfit.

At approximately $19.99 per three-pack, both sets deliver strong value. The underwear has a proven track record with over 400 reviews, while the shorts show early promise with near-perfect ratings. If you are looking for a no-fuss maternity wardrobe foundation that supports your bump without constant adjustments, this pairing is worth considering.
