Very warm, slightly itchy. Tested it during recent rather cold walk around Welsh hills, it is very warm and reasonably breathable, sizing was great for me as well.
Sauni Pure Merino Wool Sauna Hat - Felted, Insulated, Beanie - One Size
I have to say this hat looks better on than it does in the pictures, It is made from a dense wool felt. Although it is sold as a sauna hat I am sure it works both ways. It is designed to keep your head cool in a sauna but I am sure there is no wind or cold going to get through this in a British winter. I like the grey colour which tends to go with most things. Alo I like the way I can roll it longer or shorter depending how far I want it to come down.

Sauni Insulated Sauna Water Bottle - Stainless Steel, 500 mL (17.6 OZ) - Black
Works well. Bottle feels really nice and has a premium feel to it which I like. Tried it a few times and works as intended. No complaints so far
Sauni Insulated Sauna Water Bottle - Stainless Steel, 500 mL (17.6 OZ) - Black
I actually bought this after scrolling through Facebook and seeing an ad. Arrived in 2 days with tracking, works well, definitely feels more premium than some other bottles I've tried. Welcome message was a nice touch.
Sauni Insulated Sauna Water Bottle - Stainless Steel, 500 mL (17.6 OZ) - Black
This bottle made me taller! - jokes aside, can honestly say this is one of the better bottles out there. Glad I took the plunge on it. No leaks in 1 month of use and just feels nice to hold. I put ice in mine and it stayed ice cold for hours!
Sauni Insulated Sauna Water Bottle - Stainless Steel, 500 mL (17.6 OZ) - Black
Great product and price. Highly recommended if you want to get the most out of your saunas
Sauni Pure Merino Wool Sauna Hat - Felted, Insulated, Beanie - One Size
Only had it a few weeks. Nice cap and by all accounts good quality and the one size works well for my average to largish head.... Will protect the hair and that is something, but I really think the notion of it actually extending sauna times through better comfort are purely subjective and perhaps placebo AND at some point in hot saunas, could then be causing trapping of built up body heat in the head!

Great bottle
Sauni Insulated Sauna Water Bottle - Stainless Steel, 500 mL (17.6 OZ) - Black
Great quality hat, works much better than the cheaper Amazon alternatives. It’s thicker and provides more heat resistance than the cheaper ones.

Does what it says on the tin. Can wear it wet or dry, and it definitely allows me to stay in the sauna longer than usual.
Sauni Pure Merino Wool Sauna Hat - Felted, Insulated, Beanie - One Size
Great beanie really, it makes my long sauna sessions much more pleasant, while not taking away the experience from getting heated up, as it’s now just more slow paced, compared to before I used it

I love my Sauni wool sauna hat. It has extended my sessions by keeping my head cooler and is so easy to maintain.
Sauni Pure Merino Wool Sauna Hat - Felted, Insulated, Beanie - One Size
Loved It. I've had the cheaper hats you find on amazon before but they've always been terrible and a bit on the flimsy side. Thought I'd try this one and no regrets! Fits well and is clearly much higher quality than the others. :)
Sauni Pure Merino Wool Sauna Hat - Felted, Insulated, Beanie - One Size
Ok, first up, we haven't worn this in a sauna . Yet. But I can tell you it is absolutely toasty on cold days and great at keeping in all of that heat which escapes from your body through your head, inside. It is 100% wool, so no doubting the quality there. But for this reason it needs gentle hand washing and on no account put it near a washer or dryer if you want it to stay looking nice . This was a good fit for one size fits all and in fact was very comfortable. It is well-made, reasonably priced and great value.

keeps your head warmer than it looks. i love wearing dark colours so this hat goes well with alot of my winter wardrobe nice material and appearance it looks visually like it would itch you after wearing it for a while however the material is so soft and doesnt itch at all! my bro keeps trying to nab it off me! very trendy highly recommend.
Sauni Pure Merino Wool Sauna Hat - Felted, Insulated, Beanie - One Size
nice quality beanie! Super soft, thick, and comfortable — this sauna hat is made from high-quality merino wool and fits really well. The idea is that it insulates your head during sauna sessions, preventing overheating and allowing you to stay in longer without discomfort. The natural materials make it breathable and gentle on the skin. It also dries quickly after use and holds its shape after getting caught in the rain this week. Stylish, functional, and durable, it’s a proper sauna essential whether you’re out walking or at a spa.
Sauni Pure Merino Wool Sauna Hat - Felted, Insulated, Beanie - One Size
The hat appears well made. It is a felt like material so feels soft. It’s comfortable to wear for extended periods and seems to do the job well. Would be good if it came in more interesting colours than grey!
Sauni Pure Merino Wool Sauna Hat - Felted, Insulated, Beanie - One Size
This sauna hat is fantastic. It’s soft, well-made, and really does a great job protecting my head from the heat in the sauna. One size fits comfortably, and the natural wool feels premium. Perfect for anyone who enjoys a sauna, spa. Cosy, practical, and durable.
Sauni Pure Merino Wool Sauna Hat - Felted, Insulated, Beanie - One Size
I ended up giving this to my wife for the winter as it's too big for my head, but with her thick hair, it's just right for her. Quality wise it's decent, the hat feels nice to wear, and not scratchy. It's thick, and well made, it'll really keep the heat in come winter time. It's well made, no loose stitching or threads, and has asturdy construction to it, so it shouldn't damage easily.
Sauni Pure Merino Wool Sauna Hat - Felted, Insulated, Beanie - One Size
I have never been in a sauna and I don't intend starting now. That didn't stop me wanting one of these hats. I was a little concerned that, being felted, the hat would be scratchy but in fact it is quite soft and comfortable to wear. The sizing also just suited me with just enough stretch to make it snug but not tight. Another nice, but not essential, touch is the leather decal. I would not have wanted a PU (fake) leather attachment but genuine leather will age well and keep looking presentable.

Bought for a birthday present for friends with a sauna. Not sure it’s been used yet but will feedback any comments
Sauni Insulated Sauna Water Bottle - Stainless Steel, 500 mL (17.6 OZ) - Black
Great bottle but I feel it needs to have a larger capacity, it needs to be a litre if you are a seasoned sauna user. Found myself having to refill it.
Sauni Insulated Sauna Water Bottle - Stainless Steel, 500 mL (17.6 OZ) - Black
Good quality bottle however only holds 500ml Metal top part of the bottle not covered with rubber like bottom half so gets really hot in sauna Great size for the car and keeps water cold for a long time
