The sleeve cover the whole knee it’s so comfortable and really cold when first putting on what I like you can’t be mobile while cold is applied
Excellent product, much better and comfortable than standard ice packs.
Walked 36000 steps. Only thing that hurt was my flat feet. Haha. Thermax helps with the recovery
I love it. A revolution very efficiency and practice to use every day with quality.
It’s perfect, I keep it in the freezer and take it out when I’m going to elevate my leg, I have a fractured tibial plateau plus inflammation. It just fits over my knee and does the job well
I wish they stayed icy longer. That said, I love these sleeves I use them everyday! So good! Thank You!
useful and perfect fit
It's great. It's a shame it doesn't stay cold for longer (around 10 mins) but it's easy to use and helps my knee.
Great fit. Comfortable
Pratique, reste bien en place
My wife uses one before and right after playing pickleball. With having arthritis in the knee, in combination with cortisone shot she is able to enjoy playing.
Great sleeve helps my knee pain bone on bone
Excellent
Très bonne qualité 🥇
Excellent produit 👍
Ultra confortable, on adore cette marque 🥰
Very good , I cud have done size smaller but good 🏅
Je suis très satisfait de mon achat. Très efficace pour mes problèmes aux tendons d'Achille et coude. Beaucoup plus facile d'utilisation que les poches de glace, on peut les utiliser même en travaillant.
Manchon très agréable à porter, bonne qualité et super effet sur la peau. Il est déjà froid avant même de le mettre au freezer.
2éme gaine achetée 😍🙏
Super confo, très bonne qualité et arrivée vite
Best sleeve ever 💪
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 🤞
Excellent for after workout sessions. Fast warmup of the cabin. Really enjoy it !
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.
The tub is of very good quality, I use it to cool down my body prior entering the steam booth. The combination of both is perfect. I recommend.
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!
Amazed how it worked so well. Extremely simple, just place into freezer and put on. My knee feels great thanks to your product - thank you.
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.
My daughter LOVES it! it really does help to relieve muscle soreness quickly
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.
Great company to deal with, works well very simple to set up. Steams up well keeps the heat in. Would recommend to anyone.
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!
I'm absolutely loving my new lady cave! The sauna works great, the steam is fills up great in the booth. Very happy with my purchase!
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!
