Soothing Warmth That Lasts All Night
Cold feet and hands keeping you up at night? This 34-fluid-ounce heat-retention bottle with a soft knit slipcover delivers steady, comforting warmth for up to 8 hours. Crafted from odor-free PVC and wrapped in a gentle, hand-knit fabric sleeve, it's perfect for easing menstrual cramps, calming sore muscles, or simply staying cozy on chilly evenings. Unlike disposable heat packs that cool down in minutes, this refillable bottle gives you reliable, all-night relief wherever you need it—belly, back, or under the blankets.
Why You Need This
- Generous Capacity: Holds 34 fluid ounces so you enjoy 6 to 8 hours of steady heat without constant refills.
- Odor-Free Material: Medical-grade PVC construction stays neutral—no unpleasant rubber smell even after repeated use.
- Soft Knit Sleeve: Protects your skin from direct heat while adding a touch of handmade charm to your bedside routine.
- Wide-Mouth Opening: Easy, safe filling with hot tap water—no spills, no fuss, no burned fingers.
- Versatile Relief: Tuck it against your lower back during work, rest it on your abdomen during your cycle, or slide it to the foot of your bed on freezing nights.
- Reusable & Eco-Friendly: Ditch single-use heat patches and enjoy years of reliable warmth with one simple bottle.
Built for Everyday Comfort
Whether you're curling up with a book on a snowy weekend or need targeted relief after a long day, this knit-covered bottle fits seamlessly into your self-care routine. The knit fabric is removable and machine-washable, so it stays fresh season after season. Choose from five inviting colors—green, rose, orange, navy blue, or light blue—to match your bedroom palette or gift to someone who deserves a little extra coziness. And because we know winter wellness shouldn't break the bank, every order ships free across the US and comes with our 30-day satisfaction guarantee.

THE THOMLER EXPERIENCE
What Our Customers Say
Discover what makes THOMLER special.
Fills easily from the tap and stays warm through most of my movie nights.
Perfect size for tucking under the blankets without taking up half the bed.
I use this for period cramps and it's become my go-to instead of over-the-counter stuff. The removable sleeve is easy to wash when it needs refreshing, and the color I picked actually looks decent on my nightstand.
My partner was skeptical until they tried it on their lower back after yard work. Now they actually fight me for it on cold nights, so I'm thinking about grabbing a second one in the navy color.
The wide opening makes filling it straightforward without worrying about splashing hot water everywhere. It's held up well through multiple winters and the knit hasn't pilled or fallen apart like I thought it might.
