    Rated 5 out of 5 by from Great product - read my feedback to other buyers I bought 2 of these. There is no substitute for 100% wool. Previously I had purchased the Vigilante brand from Anaconda and loved the warmth. But they could not supply promptly in my recent winter purchases. I am a shift worker, working outside in the elements each and every night. I found this product interesting as it differs from Vigilante brand in terms of cut style. It has a low wide neck, I now think this is a positive as it becomes a hidden layer. You could even wear it under a nice shirt and go out for dinner and no one would see it. The sleeve has a long firm cuff, this is a positive as well - in time the product will loosen up. The Vigilante brand that I have has no cuff and slides down outside my next layer all of the time. It's great product, warm and money well spent. I can't comment on its long term durability at present. But I am happy with the purchase and my on line purchase and delivery - 1st class.

    Rated 5 out of 5 by from Great investment I bought the merino base wear long sleep to and long Johns in anticipation of a trip to Europe in December this year. I was pleased to find both items live up to its promises. The fit was comfortable (I am tall and usually find the arms and legs a bit short) but these fit perfectly. They were soft against my skin. It is really true that you can wear them for several days and they do not retain odour and once washed they dry quickly. I have practically lived in mine since buying it and have bought another pair. The items were pricey but well worth their money.

    Rated 5 out of 5 by from Good buy! I find Kathmandu Merino's more effective than other brands. I use my 195Merinos all year - effective and comfortable all year around. Because they are thin they are also quick drying so great for when you are away from a washing machine. They are easily washed in a washing machine on a wool setting.

    Rated 4 out of 5 by from A welcome variation on merino base layers Good colour, great sleeve finishing as you can have a neat cuff if the sleeves are a bit long. A bit tight around the middle for a unisex/male sizing.

    Rated 5 out of 5 by from Very comfortable and warm Worn overnight in a 150 km run in Canberra, very streamlined, no chaffing or bulking with backpack, minimal over garments required to maintain body temp, great product.

    Rated 5 out of 5 by from merinoBASE Unisex Long Sleeve Top - Raspberry I bought this for my Mum. She said it was very warm and not itchy at all (usually allergic to wool). The price was only $60 which is very good for a micro-fibre garment. I will buy the merino bottoms in your next sale. Thank you :)

    Rated 5 out of 5 by from My winter faves! Great quality merino, that doesn't peel. Lovely fit through body especially body length and snugness of cuff. Love these so much I have 4! Just wish they did more colors, like light grey, charcoal, burgundy.
