This is perfect for under your helmet or hood during those really cold days. This 'lid' surprisingly keeps me toasty although it is quite thin. I would recommend this to those that are into the technical side of things as this does a great job at blocking the wind as advertised. I will buy another when I need it.
So, I've used this a few times. It keeps your head pretty darn warm. I also like that it's low profile. About my only complaint, and this is a nit, is that the very bottom of ear lobes are uncovered.
This hat was awesome. It's very comfortable and keeps my head nice and warm. I haven't had a chance to wear it hiking yet but I will be confident that this hat will satisfy my needs.
Really wanted to love this product, I have a crush on everything Mountain Hardwear. The good and the bad of this garment is the Airshield layer. The Airshield layer makes for a great inner layer that is windproof. Then there is an outer layer of fleece material. It seemed liked there was too much material in the outer layer compared to the inner layer. This left a lot of material at the top of the hat to bunch up. This caused two problems for me. First of all
This hat is very warm and is great in the wind. I do wish it was a little deeper to go a little further over my ears. Perhaps it is just my larger than average head.
