Maximum Protection. Full-Coverage Comfort.

For your heaviest days, dependable protection should still feel soft, secure and comfortable to wear.

The EvaBody Super Absorbency Longline Boyshort combines a cotton-rich body with an extended boyshort silhouette for greater coverage through the hips, back and upper thighs. The longer-leg design offers a supportive, stay-put fit that moves comfortably with you, making it ideal when you want extra reassurance without sacrificing softness.

Designed for very heavy flow, overnight wear and times when maximum absorbency matters most, it provides high-performance protection to help you feel dry, supported and confident for longer. Its full-coverage shape also makes it a practical choice for long days, sleep and moments when you want your underwear to work harder for you.

It is also a supportive option for postpartum bleeding and recovery, heavier bladder leaks or urinary incontinence, offering added coverage and absorbency when comfort and reassurance are especially important.

Maximum absorbency. Extended coverage. Confidence when you need it most.

The best backup for bladder leaks

I have occasional bladder leaks and this pair gives me so much confidence when I'm out and about.

I can wear these all day confidently

I can comfortably wear these all day and forget about my period, which says everything.

This made my periods so much less stressful

Since buying these from EvaBody, my heavy days have become so much less stressful and easier to manage.

Very good but I sized up

The protection is excellent. I just went up a size on my second order because I like a roomier fit.

A genuinely high-performance pair

This pair really performs. I wore it for a long workday and felt comfortable and secure the entire time.

Bought these for my daughter and she loves them

I bought a pair for my teenage daughter because she has very heavy periods and she now asks for them every cycle.

The peace of mind is worth it

The peace of mind these give me overnight is honestly priceless.

No leaks even on day two

No leaks, no discomfort and I didn't need to layer extra products on day two of my cycle.

Comfortable but I prefer a shorter leg

Very comfortable and supportive.

I keep this pair for my toughest days

I save this pair for my toughest days because I know it can handle anything.

Exactly what I needed for post-partum recovery

This was my first EvaBody purchase after having my baby and I was genuinely impressed with how comfortable these are.

Feels like wearing soft shorts

These feel more like soft cotton shorts than period underwear, which I love.

Really good for heavy flow

They work really well for heavy flow. I just usually prefer less coverage during the day.

Perfect for long days away from home

I wore these during a full day of travel and never once worried about leaking.

Great protection but warmer than my other pairs

Really good quality and absorbency. I personally reach for this style more in cooler weather.

I slept through the night for once

I honestly slept through the night for the first time in ages because I felt so secure in these.

A lifesaver after having my baby

I bought these a few weeks after giving birth and they were amazing for post-partum recovery and light leaks.

The extra coverage is incredible

The amount of coverage is incredible and makes me feel completely protected on heavy days.

Very absorbent and comfortable

The absorbency is excellent and they're very comfortable. I just find the longer leg a little warmer in summer.

The only pair I trust overnight

This is the only pair I fully trust on my heaviest nights. I finally sleep without setting alarms to check for leaks.

Excellent for Travel Days

Used these on a long-haul flight—, so much better than relying on tampons or pads alone. Only downside is they felt a little warm after several hours. Still a great travel option.

Comfort + Function = Perfect

They feel like soft cotton boxers but work better than any pad I’ve used. Plus, no awkward rustling or shifting throughout the day.

Wish They Dried Faster

Amazing product, but because of the absorbency, they take a while to air-dry after washing.

Best for Long Workdays

I work 12-hour shifts, and these get me through the whole day. No pad changes, no worries. Just freedom.

Absorbent and Reliable, but Bulky

These hold a lot, as promised, but they do feel a bit thick. That said, I’d rather deal with bulk than leaks. Great for overnight!

No More Overnight Pads!

I used to double up pads at night—no more! These keep me dry and comfortable through the entire night. Game-changer.

My Period Superhero Underwear

Seriously, 12 tampons worth?! I didn't believe it until I tested them. I stayed dry all day, and no odour at all. Total win.

Postpartum Lifesaver

Used these after giving birth and they were perfect for managing postpartum bleeding. Comfy, breathable, and ultra-absorbent.

Ultimate Coverage and Confidence

These boyshorts are incredible! I wore them on my heaviest day and felt secure and dry for over 10 hours.

Great for Sleep and Lazy Days

Perfect for lounging or sleeping on heavy days. They’re soft, comfy, and actually stylish for a full-coverage option.

Great

I was amazed by the absorption capacity and since I am a gymnast this is just perfect for me during my period to perform. Will definitely try the other heavy flow range too.
