It will be a bit tight for those with big heads. It feels like a swimming cap when worn. The material is comfortable.

I guess it depends on the shape of your head, mine tends to fall upwards, I have to straighten it often for my taste.

I really like it, I've used it for many sports, cycling, rollerblading, skiing, running, hiking. It's incredibly thin, at first it may not seem warm enough, it's "airy", but being merino it's absolutely great. It wicks away sweat well, since it's also airy, so I like it better than other running caps. Because of its thinness, it goes easily under helmets. I would buy it again.

Light and space-saving: it's a good product

Good quality

After good experiences with merino socks, shorts and a t-shirt from Decathlon, I am overall disappointed with this hat. It is good for low-intensity activity. The moment I start sweating a lot, the hat turns into a wet rag which is not at all comfortable and takes an extremely long time to dry - 24 hours at room temperature on a hanger and the next day it is still damp. But for normal, undemanding wear it is fine.

close to the head, good warmth and comfortable to wear

Warm and breathable at the same time. It is not very thick, just right for winter activities. I use it for running and hiking. You can put a helmet on it.

Nice hat, I use it mainly for running because it doesn't look like a swimming cap like most "running" hats.

Okay

Good for spring or fall. Too thin for winter.

The FORCLAZ MT500 Merino trekking hat is a great choice for any outdoor enthusiast! Made of high-quality merino wool, it is incredibly soft, warm and breathable. It works perfectly on cold days, providing thermal comfort while not causing overheating.
