The Emergency Kit · Wearable Far-Infrared Warmth
품 — the Korean word for the warm space in someone's arms. Warmth where you hold it.
Litual stays on the bed. Poom goes with you. For the days the pain climbs, the nights the mind won't settle, the hotel bed that isn't yours — a matte black band that slips under your clothes and holds one place steadily warm until your body lets go.
Small enough to live in your bag. Invisible enough that nobody knows it is there.

The Old Way
When You Reach For It
Hotel rooms, guest rooms, night trains — the first night somewhere unfamiliar rarely goes well. Poom brings the one thing your body already recognizes, so the bed matters less.
A lower back that has had enough, a waist that sat too long, a belly that wants to be held. Steady warmth, exactly where you place it, for as long as you keep it there.
Some evenings the thinking does not stop on request. Warmth low on the belly or the back gives the body something else to attend to, and the shoulders usually follow.
Moments
Lower back after deadlifts. A waist that sat through leg day. Poom brings steady, deep warmth to worked muscle — recovery that happens while you shower, stretch, or do nothing at all.
First nights in unfamiliar beds — hotels, guest rooms, anywhere that isn't home yet. Wrap Poom on like the hot-water bottle you used to hug, minus the boiling and the 3am cold spot. Familiar warmth makes any bed yours.
Back-to-back calls, a chair that's winning. A warm hand at your lower back, invisible under your shirt. Nobody in the meeting knows. Your body does.
Period days. Heavy-lunch days. The days your middle just wants to be held. Steady warmth, low on the belly, for as long as you need it.
Why Poom
Far infrared sinks up to 6cm beneath the skin — past the surface, into the muscle that's been holding on all day. Deep, even, steady. Not the scalding-then-lukewarm cycle of a hot-water bottle.
No leaks, no burns, no toxic adhesives. EMF-free construction, automatic shut-off, Teflon-coated warming yarn woven — not glued — by hand in Korea.
Slim enough to disappear under a shirt or a base layer. An adjustable band that fits every body, powered by the power bank you already own.
Designed to Be Simple
Connect. Plug Poom into any USB power bank.
Place. Belly, lower back, waist — adjust the band to where today needs it.
Choose. Three levels, one smart switch.
Carry on. Wear it under your clothes and get on with your day. Warmth, for hours.
Precise, Not Complicated

Verified Reviews
I've had endometriosis for 8 years and literally couldn't function during my period without a hot water bottle. Core Comfort is a game changer — it heats up in seconds, lasts for hours, and I can wear it under my clothes to work. No more boiling water at 3am.
Lisa T. · ✓ Verified원래 생리통 완화용으로 샀는데, 허리 통증에도 너무 좋아서 매일 쓰고 있어요. 보조배터리로 돌아가니까 회사에서도 쓸 수 있고, 얇아서 옷 안에 넣어도 티 안 나요. 진짜 강추합니다.
김수진 · ✓ VerifiedJ'ai des douleurs chroniques au dos depuis un accident de voiture. Core Comfort est devenu indispensable. La chaleur infrarouge pénètre beaucoup plus profondément qu'une bouillotte. Je l'utilise au bureau, dans l'avion, même au restaurant. Personne ne le voit sous mes vêtements.
Marie L. · ✓ VerifiedI have PCOS and the cramps are brutal. My heating pad at home works but I can't exactly bring it to the office. Core Comfort solved that problem completely. Wearable, discreet, and the heat actually reaches deep. Taking off one star because shipping took a while to the US, but the product itself is 5/5.
Rachel S. · ✓ VerifiedI bought this for lower back pain from sitting at a desk all day. The far-infrared heat is noticeably different from a regular heating pad — it feels like it goes deeper. Battery lasts my entire workday. Genuinely one of the best purchases I've made.
Anna B. · ✓ Verified엄마가 허리가 안 좋으셔서 선물로 드렸는데, 너무 좋다고 하셔서 저도 하나 샀어요. 생리통에 진짜 효과 있고, 핫팩처럼 데일 걱정도 없어서 안심이에요. 충전식이라 어디서든 쓸 수 있는 것도 큰 장점.
이현주 · ✓ VerifiedI'm a yoga instructor and recommend this to all my students with chronic pain. The build quality is excellent, it's incredibly thin, and the heat distribution is even. I've now bought four — one for me and three as gifts for friends with period pain.
Sophie H. · ✓ Verified毎月激しい生理痛に苦しんでいましたが、Core Comfortを使い始めてから痛み止めの量が半分になりました。遠赤外線の温かさは貼るカイロとは全然違います。体の奥から温まる感じで、持続時間も長いです。
田中あゆみ · ✓ VerifiedI see so many women suffering with menstrual and postnatal pain. Core Comfort is the first product I genuinely recommend to my patients. Safe, effective, portable. The far-infrared tech is backed by real science, not just marketing fluff.
Emma J. · ✓ Verified자궁근종 때문에 복부 통증이 심했는데, 코어 컴포트가 많이 도움이 돼요. 약을 먹기 싫을 때 대안으로 쓰고 있고, 원적외선이라 일반 핫팩보다 깊은 곳까지 온기가 전달되는 느낌입니다.
박은지 · ✓ VerifiedThe heat therapy itself is amazing — my chronic back pain has reduced by about 50% on days I use it. The strap took some adjusting to get comfortable, but once I figured out my ideal positioning, it was great. Solid 4 stars, would be 5 with a better strap design.
Julia K. · ✓ VerifiedAntes perdía 2-3 días al mes por dolor menstrual insoportable. Core Comfort me permite funcionar normalmente. Lo llevo bajo la ropa en la oficina y nadie lo nota. La batería dura todo el día laboral. Es una revolución para las mujeres que sufrimos dismenorrea.
Claudia R. · ✓ VerifiedEndo warrior here. Core Comfort is now permanently in my bag alongside my painkillers. But the amazing thing? I'm reaching for the painkillers less and less. The deep heat genuinely helps manage the pain. This isn't a gimmick — it works.
Olivia M. · ✓ Verified장거리 비행기 탈 때 허리가 항상 아팠는데, 코어 컴포트를 허리에 대고 있으면 훨씬 편해요. 보조배터리만 있으면 되니까 비행기에서도 쓸 수 있고, 가볍고 얇아서 짐이 안 돼요.
최지은 · ✓ VerifiedI work at a desk 10 hours a day. Lower back pain was becoming chronic. Core Comfort at medium heat during work hours has dramatically reduced my evening pain levels. I barely need my weekly massage anymore. The product pays for itself.
Catherine B. · ✓ VerifiedI hike and cross-country ski regularly. Wearing Core Comfort under my layers keeps my core warm without bulky clothing. The battery lasts through a full day hike. Game changer for anyone active in cold climates.
Hanna S. · ✓ Verified제가 회사에서 허리에 대고 있으니까 동료들이 뭐냐고 물어봐서, 설명해줬더니 3명이 바로 구매했어요 ㅋㅋ 특히 생리통 심한 동료가 너무 좋다고 매일 감사하다고 합니다.
정유라 · ✓ VerifiedI was taking ibuprofen almost daily for period and back pain. Since getting Core Comfort, I've cut my painkiller use by 80%. The far-infrared heat addresses the root cause rather than just masking symptoms. My stomach thanks me.
Megan O. · ✓ Verified着物の着付けの仕事をしていますが、冬場は特に冷えがつらかったです。Core Comfortは薄くて着物の下に付けても目立ちません。お客様にも勧めていて、好評です。日本の寒い冬にぴったりです。
佐々木里奈 · ✓ VerifiedThe heating effect is genuinely therapeutic — much deeper than a regular heat pad. My only complaint is the USB cable could be slightly longer for more comfortable positioning. But the product itself delivers on its promises. Pain relief is real.
Laura P. · ✓ Verified주말마다 등산하는데, 하산 후 허리와 다리 근육통이 심했어요. 코어 컴포트로 부위별로 대면서 쉬면 다음 날 컨디션이 완전히 다릅니다. 등산 동호회 회원들에게도 추천하고 있어요.
김민서 · ✓ VerifiedJ'ai montré Core Comfort à ma gynécologue qui a été impressionnée par la technologie infrarouge. Elle m'a confirmé que c'était une excellente alternative aux anti-inflammatoires pour les douleurs menstruelles. Depuis, elle le recommande à d'autres patientes.
Isabelle C. · ✓ VerifiedPlayed rugby for 15 years, and my back is paying the price. Core Comfort gives me consistent relief without the faff of hot water bottles or messy heat patches. It just works, every single time.
Emily R. · ✓ VerifiedFinalmente un prodotto di salute che non sembra un dispositivo medico. Core Comfort è elegante, sottile e si nasconde facilmente sotto i vestiti. E soprattutto funziona davvero — il calore infrarosso è completamente diverso da una borsa dell'acqua calda.
Andrea M. · ✓ Verified생리 첫날에 항상 결근했는데, 코어 컴포트를 알고 나서는 아프면서도 버틸 수 있게 됐어요. 옷 안에 차고 있으면 아무도 모르고, 진통제를 안 먹어도 되는 날이 많아졌습니다.
조은비 · ✓ VerifiedMy physio uses infrared lamp therapy. This is essentially the same thing but portable. I use it 4-5 times a week and my chronic hip pain is the most manageable it's been in years. At €149, it's paid for itself many times over compared to physio sessions.
Helena V. · ✓ VerifiedTrabajo sentada 8 horas y los dolores de espalda eran constantes. Core Comfort ha sido mi salvación. Lo conecto a mi power bank, lo pongo en la zona lumbar y puedo trabajar sin dolor. Mis colegas ya me preguntan dónde comprarlo.
Mercedes G. · ✓ VerifiedThe pain relief is legit — probably the best non-pharmaceutical option I've tried for cramps. Would love a waterproof version for bath time. But honestly, that's me being picky. The product does exactly what it says.
Kate W. · ✓ Verified필라테스 강사인데, 수업 전후에 코어 컴포트로 코어 부위를 워밍업/쿨다운하면 효과가 좋아요. 회원님들 중 허리 통증 있으신 분들께도 추천하고 있고, 반응이 정말 좋습니다.
이지현 · ✓ VerifiedCold climate + 9 hours at a desk was destroying my lower back. Core Comfort at medium heat for a few hours while working has eliminated my need for weekly chiropractor visits. The savings alone have paid for the product twice over.
Astrid N. · ✓ Verified札幌の厳しい冬、外出時にCore Comfortをお腹に巻いて出かけます。通常のカイロと違い、遠赤外線の温かさは深くまで届きます。バッテリーも長持ちするので一日中安心です。もう冬の必需品です。
高橋真理 · ✓ VerifiedSeriously, this product should be more well-known. I tell everyone about it. The technology is legitimate, the build quality is excellent, and it actually makes a difference in daily comfort. My period pain management has been transformed.
Jennifer L. · ✓ Verified출산 후 복부와 허리 통증이 심했는데, 코어 컴포트 덕분에 많이 나아졌어요. 수유하면서도 착용할 수 있어서 편했고, EMF 프리라 아기 옆에서도 안심하고 사용할 수 있었습니다.
신예진 · ✓ VerifiedI've spent hundreds on wellness products that sit in drawers. Core Comfort is the first one I actually use daily. Period pain, post-gym soreness, cold weather warmth — it handles all of it. Simple, effective, beautiful design.
Freya D. · ✓ VerifiedWhat sold me is how thin it is. I wear it under my blouse at work and nobody notices. The warmth keeps my chronic lower back pain at bay during long meetings. This is genuinely the most useful health product I own.
Clara S. · ✓ Verified겨울 캠핑 갈 때 꼭 챙겨요. 보조배터리만 있으면 되니까 전기 없는 곳에서도 쓸 수 있고, 등에 대고 있으면 추위를 잊을 수 있어요. 캠핑 커뮤니티에서도 화제입니다.
박소현 · ✓ VerifiedNobody talks about how cold office AC is in summer. My lower back seizes up every afternoon. Core Comfort at low heat is the perfect solution. Invisible under my dress, effective all day.
Alice T. · ✓ VerifiedTook about 2 weeks to arrive in Australia but the product itself is excellent. The far-infrared heat is noticeably different from conventional heating pads. My physiotherapist was impressed. Just wish international shipping was faster.
Nicole F. · ✓ Verified임신 초기에 복부 불편감이 있었는데, 의사 상담 후 낮은 온도로 사용했어요. 약을 못 먹는 시기라 비약물적 방법으로 통증을 관리할 수 있어서 정말 감사했습니다.
윤채원 · ✓ VerifiedI was spending €40/week on physiotherapy for chronic back pain. Core Comfort at €149 has reduced my physio visits to once a month. It's literally saving me over €100/month. The product paid for itself in 6 weeks.
Petra K. · ✓ VerifiedI bought this for myself, then for my mom, my sister, and my best friend. The reaction is always the same: 'Why didn't I know about this sooner?' Period pain management should not involve boiling water in 2024.
Lena M. · ✓ Verified2023년에 구매해서 2년째 쓰고 있는데, 성능 저하 없이 잘 작동합니다. 내구성도 좋고 세탁해도 문제없어요. 주변에 10명 넘게 추천했고 다들 만족하고 있습니다. 가성비 최고의 건강 투자예요.
장서윤 · ✓ VerifiedBefore You Ask
No. Poom is slim by design, and the power bank tucks into its own pocket. In a meeting, at the gym, on the metro — it's your secret.
Between sessions. Warmth is the recovery you don't have to work for: wrap it on a worked lower back or waist after training and let deep, steady warmth do its quiet job while you get on with your evening.
Warmth on the belly is one of the oldest comforts there is, and Poom was designed with exactly those days in mind — steady, deep, and with you wherever the day goes. No boiling water required.
Depends on the level: up to 6.5 hours on Low, 3.5–4 on High. It runs on any standard USB power bank — the one in your bag works.
Poom is EMF-free, shuts itself off against overheating, and its warming yarn is Teflon-coated and woven without adhesives. It's certified (CE, UKCA, OEKO-TEX® fabrics) and built for daily wear. If you're pregnant or have a specific health condition, check with your doctor first.
Wipe the shell clean; the breathable lining keeps it fresh against the skin. Full care instructions come in the box.
