This wool beanie has become my go to hat.
I have a bunch of hats. This has become my number one choice to wear on cold days around town, working in the yard or when hiking in the mountains. First it is very comfortable. It breathes well and dries quick. It is light weight and easily fits in a pocket. I highly recommend this hat.
Great purchase for comfort in the cold!
Keeps my head warm but not to where I get hot or sweaty. If it’s really cold I’ll put another stocking hat over this one for the added warmth and moisture wicking benefits
Great beanie.
Just got back from a backpacking trip where the temps were in the mid-20’s. This hat kept me warm. It fits me well; it covers my ears and is not bulky. It did not slip off in the sleeping bag at night, either. I initially purchased because of the materials- wool and nylon. There is no polyester like so many other beanies offered today, which tends to hold odor and are reputed to have environmental hormones.
Keeps me head warm but
When I first put this beanie on, after I washed it, I really liked it. But the negative aspects of this beanie reared its head. First I don't like the tags. I have cheaper beanies that have inked tags on the inside and a logo on the outside I like those because of that. This Beanie has an outside tag and an inside tag that are annoying. I don't wear it often and the stitching is starting to come off the seams. I'm realizing this will fall apart quickly. Yeah I could've brought it back because it happened within the first 30 days but I am too busy for that. The good about the Beanie is it keeps my head very warm, and it fits very well. Would I buy another No, I'll purchase something different next time.
Too Small for Large Head
Based on a reviewer that said this fit his 7 1/2 noggin, I gave it a shot. Yes, the beanie stretches quite a bit and will cover a large head, but on me it feels noticeably too small (over stretched) and gradually creeps up and off. I have to keep tugging it down over my ears. Seems like a very nice hat otherwise. Works ok for me under a bike helmet, which keeps it in place.
"One Size" works on 7 1/2 head
This hat has many great reviews, and I agree with them. But many "one size fits all" hats are too tight for my 7 1/2 inch head, so I wondered how it would fit. While it is slightly more snug than optimal, it has never felt too tight or annoying. I wear it often and never feel like I need to try to stretch it wider. I would definitely buy it again.
Love this warm beanie
The fit is great, comfortably fitting my XL head, and is soft and super warm in cold conditions. My only complaints are this item is no longer available (I would absolutely buy again) and should be in multiple colors (i.e., blue, green, etc.).
Great beanie for hiking and biking.
Fits great, not too tight, not too bulky, and warm so far down to the 20's. I expect it will be warm at lower temps too. Fits easily under my bike helmet as well.
Very warm
This stocking cap is warm and light it allows the air to penetrate without loosing warmth so when it is cold it keeps you warm and when that sun comes out it doesn’t get to hot in my opinion and can be breazy with out getting cold. I was looking for a product as close to the military polartec stocking caps and this has been pretty close so far.
Warm and Versatile Beanie
Beanie is adequately warm, crush-able and so easy to pocket or pack; thin enough to layer under a wool knit beanie or helmet. Wife thinks it would look better on a younger man... she's probably right (I don't take it personally); but for me, knowing it won't pop out of my pocket like a bulkier knit beanie is worth not fitting "the look".
