These sleeves are incredibly convenient and work great! They get really cold, slip on easily, and stay comfortably in place while I move around. I use the large size for my knee and the smaller size for my calf and ankle. They're so much easier to use than traditional ice packs. I absolutely love them and will definitely be buying more!

Super comfortable, soft, and made with great-quality materials! The cooling sensation feels amazing, and the sleeve is lightweight, fits perfectly, and slips on and off effortlessly. So much more convenient than traditional ice packs or frozen peas! I'm really glad I discovered Thermax. It's a fantastic product for arms, knees, legs, and more. Highly recommend!

Having the Thermax has been a huge relief for me. I always make sure that I place them on both of my knees before and after my long day at work and they're a total game changer.
This nordic steam cabin is big enough for one, small enough to keep indoors without using up too much space. I take it outside during summer as it is very light. So far no issue with it. Finger crossed 🤞
I have been wanting to get a personal sauna for a long time now but didn’t want to break the bank on one as I do not have much room in my apartment for one. This thing fits nicely in my bathroom and it’s portable if I ever want to take it camping or something. Overall I would recommend this sauna, this seller, and for you to go ahead and get one for yourself.
Love our sauna. After 2 weeks of consistent use I already noticed feeling less general joint achiness and I am sleeping better for the first time years!
This thermax sleeve is great, specifically the ones I bought was for my elbows/forearms. Takes a few times to get it to as cold/hot as desired but once you have that down, it really helps!
I have used lots of different hot/cold packs. I like this brand the best. These Optimalax sleeves are form fitting and do an excellent job of covering the whole area with heat or cold. IMHO, these are superior to any others I’ve seen or used.
I have had my Thermax tub and have been consistently plunging for 28 days. I keep mine outside on the patio and it has withstood freezing temperatures with no issues. I filled the inflatable pillow thing with water and put it in the freezer to use as an ice pack when the weather doesn’t keep the water as cold as I would like it. Not sure if that’s what it’s for, but it has worked for me. I am happy with the quality of the tub and appreciate the ease of assembly along with the accessories provided. I love making cold water therapy a part of my daily morning routine.
Love using this. Works great doesn’t take up a lot of space in my apartment and really easy to set up. Have been sleeping like a baby since I started using it. I like this Thermax brand...😍
I absolutely Love this Sauna!! I’m a Stroke Survivor (from Birth Control!), so I cant wait to see how this changes my continued Journey. Ive made a full recovery from the stroke, so just continuing to try to live as healthy as possible. I notice I sleep much better on the days I use it. 🫶🏻 I’ve shared it with friends bc I’m completely impressed with the quality! Love it!
So, let me tell you about my new favorite thing: the Thermax Steam Sauna. It's like having a spa day in the comfort of your own home, and I am here for it!
First off, setting this baby up was a breeze. No complicated instructions or weird tools required. Just unpack, plug in, and you're good to go. Plus, it looks sleek and modern, so it fits right into my space without sticking out like a sore thumb.
Now, onto the good stuff – the steam! Once I step inside, it's like a warm, cozy hug from the universe. The steam gets going fast and before I know it, I'm sweating out all the stress and toxins from the day. It's seriously detoxifying and leaves me feeling like a million bucks.
But wait, there's more! I love that I can customize my sauna sesh with the adjustable temperature and timer. And don't even get me started on the aroma diffuser – it's like adding a cherry on top of an already amazing experience. Lavender oil, anyone?
Overall, the Sauna has become a non-negotiable part of my self-care routine. Whether I need to unwind after a hectic day or kickstart my morning with some zen vibes, this sauna has got my back. So, if you're looking to up your relaxation game, do yourself a favor and get one of these bad boys. Trust me, your mind, body, and soul will thank you.
I bought a Thermax hat some years ago and was very happy with the quality. Recently i purchase a similar hat that looked exactly like the Thermax. I was very disappointed with the quality, itchy fabric, way slimmer so not keeping the cold temperature long enough. I recommend to go for the original and not a replica. Maybe a bit more expensive but the quality is definitely guaranteed...
I was pleasantly surprised at how good this felt. I have not had a full blown migraine, thankfully since I bought it so the true test is pending. Overall so far I am happy with this product. Blue color and fabric is SO NICE!
I never write reviews, but this foam roller is amazing. I do triathlons so I basically need to roll everywhere, but a regular foam roller wasn't doing anything for my calves, upper back, and lats. This roller is different as it does have grooves. You can really go deep into tissues for best relief.
I had no idea it was possible to get rid of calves strain so easily. Then I saw a video of someone rolling its cave on this roller and decided to take a plunge. I noticed immediate relief after using it. Super happy!
