HigherDOSE vs MiHIGH sauna blankets, and when a blanket is enough

HigherDOSE vs MiHIGH side by side

Prices are US prices on each maker’s page, before tax, checked on October 13, 2026. The MiHIGH price is a sale price, and the HigherDOSE price is not. Every figure is the maker’s own, and none was measured independently.

Which one to buy

Both are lie-down blankets for one person, and neither publishes enough to compare heat output. So the choice comes down to price, returns and whether you can get one.

• You want to try a blanket and keep a way out: HigherDOSE. You get 120 days to return it even after use, with a prepaid label⁴. HigherDOSE says it heats up to 175°F, and its store listing includes a free towel insert^{1, 2}. The catch: it costs $520 more than the cream MiHIGH. The warranty lasts one year and excludes liquid contact, which matters for something you sweat in³. The product page also lists no wattage, size or safety listing¹.
• You want the cheapest way in and won’t send it back: MiHIGH, once it’s back in stock. It’s $179 on sale for cream and $199 for black^{6, 7}. MiHIGH publishes a temperature range in 5°C steps and a 330 lb user limit^{6, 10}. The catch: both colors were sold out on October 13, with no restock date⁶. An opened blanket can’t be returned⁹. CE is the only certification MiHIGH names⁶.

The return policies are the real difference

HigherDOSE gives you 120 days from delivery to return the blanket for a refund, even after use⁴. It has to come back in like-new condition, or the return may be denied⁴. HigherDOSE’s returns portal supplies a prepaid label⁴. Amazon purchases get a separate 45-day guarantee⁴.

MiHIGH’s product page says “Not for you after 30 days? We’ll refund your entire purchase, no questions asked.”⁶ Its refund policy says otherwise. A return must be unopened and in its original packaging⁹. You pay return shipping plus a 15% restocking fee, about $27 on the cream blanket⁹. Go by the policy, not the banner.

The warranties are close in length but differ in detail. HigherDOSE covers one year from purchase and excludes liquid contact, pet damage and normal wear³. MiHIGH covers 12 months from dispatch, not delivery, and chooses whether to repair or replace⁸. The warranty comes from MiHIGH Pty Ltd in Australia and falls under Queensland law⁸. Its refund policy also gives a shorter window to report a fault, 14 days, than the warranty’s 30^{8, 9}.

What neither maker tells you

Neither maker publishes power draw, so running costs are unknown for both^{1, 10}. Neither names an ETL or UL listing, and both make low-EMF claims with no figure or test^{1, 6, 10}. HigherDOSE doesn’t give the blanket’s size or any setting below 175°F¹. MiHIGH describes no timer or automatic shut-off^{6, 10}. If a US safety listing matters to you, ask before you buy.

Some details conflict on the makers’ own pages. HigherDOSE’s store listing includes a free towel insert, while its product page FAQ says the insert is sold separately^{1, 2}. MiHIGH’s product page lists a Poly Oxford exterior, and its FAQ says leather^{6, 10}.

Both pages make health claims without studies. HigherDOSE says it heats up to 175°F “to boost circulation, detox & relaxation at home” and cites no study¹. MiHIGH claims up to 300 to 600 calories burned per session, with no study or method⁶. MiHIGH’s FAQ says to ask your doctor first if you’re pregnant, have a pacemaker or other implant, or have heart disease¹⁰.

Is a blanket enough?

A blanket is the smallest, cheapest way to try infrared heat at home. You lie inside it alone. MiHIGH says to wipe it down and let it dry before you fold it away^{6, 10}. HigherDOSE says to wear long sleeves, pants and socks so your skin stays off the heated surface¹. A cabin lets you sit up, and a two-person cabin lets you share.

Of the cabins we cover, the cheapest with a listed price is Sunlighten’s one-person Signature I, at $4,999 on sale¹³. It needs its own 120 V, 20 A circuit and a 37.8 × 39.8 in spot with 4 in to the walls¹². For two people without an electrician, Health Mate’s Enrich 2 lists at $5,300 and plugs into a standard 15 A outlet¹⁴. Either costs more than seven times the HigherDOSE blanket, before any electrical work.

On paper, the top temperatures are close. HigherDOSE says its blanket reaches 175°F, and Sunlighten says the Signature I reaches 170°F^{1, 12}. Those are the makers’ own figures, not measurements, so they don’t tell you which session feels hotter. Our sauna evidence review didn’t find a sauna blanket among the trials it covers, so read it before buying either for a health effect.

A blanket is enough if you’ll use it alone, lying down, and want to try heat before committing to a cabin. Choose a cabin if you want to sit up or share sessions, and you have the floor space and the circuit. Our infrared cabin comparison covers ten of them.
