I love the Oasis 200 Crewe neck. Wanted navy for ages and it is never in the sale but got discount on the 20% off day. Very lucky. Great shape, fitted and flattering. Slim fit but plenty of room under armpits due to special shaping which makes this design better than competitors. Fit finder suggests perfect fit. I am broad shouldered but fits so well. Many other brands are too narrow on shoulders for me , then baggy. This is a sleek shapely design. Fabric superb. Washes well. Even spun these tops at 1400 in machine by mistake and they come out fine. Ironing optional. I hang on the line and the shape stays good. Colour lovely. I have 3 of these now. A turquoise and a mink scoop neck. Prefer the neck coverage of the Crewe to the scoop.

I have a crew neck 200 Oasis long sleeve that I purchased years ago. I love that they now have the option of a v neck!!! Perfect for layering under sweaters where the crew neck tends to poke out!The newer version is very nice and soft and seems to be good quality, but I like the fit of the older one more, and also the fact that it doesn't have any branding. The new version is bigger, and it also has branding on the sleeve which I dislike (though it's subtle!). I also liked that the older version had a real tag, not a painted on one. I'm worried the painted on sticker will not hold up. The slimmer fit from years past fit my shape much better too, so i'm sad this one is larger! I'm hoping the new one will shrink slightly after the first wash.

I think I have 5 of these that I've bought over the years in solids and stripes. They're thick enough to not be see-through like many of the thinner Icebreaker shirts in light colors. They are also comfortable, fitted, but not too tight. I'm a curvy C-cup, and they're very flattering. I also really like that the collars are high.The all-wool makes them not retain stink after washing like many of the mixed fabrics do. I easily can wear 1 shirt for a week without washing, assuming I don't get it dirty from mud or food and need to wash because of that.I wish these were available in short sleeve at this weight. I'd get a larger size to have slight looser t-shirt fit if those were available.

An excellent top by Icebreaker. It is on the pricier side but on the other hand, it’s 100% merino wool and for that, I think it’s well worth it. I don’t normally purchase casual clothing, but after wearing this 100% merino base layer, I can’t shop for anything less. It is lightweight and absolutely very warm. It’s perfect for travelling, especially when travelling light. I wear medium size and it fits perfectly.To start my new collection, I just purchased another two similar clothing from icebreaker.
These 200 Oasis long sleeve tops are just amazing. I would wear one all the time if I could. I've had no trouble with laundering them either, and the top gets softer with each wash. (I do not put them in the dryer, but they dry really fast when hung up.) I have black, and right now I'm sleeping in it for cold weather. But the weave is so nice and fine that it (or the short sleeved one which I also have) could be worn under a blazer or as a regular top regardless of being active wear. I expect these tops to last for many years. BTW - I am a 6' tall, middle-aged amazon female, and the XXXL fits all my curves just right. (To be fair, I can also wear the XXL a little more tight - I'm kind of right between those two sizes in the men's.) I'm no go on their women's sizes. ... MoreThese 200 Oasis long sleeve tops are just amazing. I would wear one all the time if I could.

The Men's Oasis 200 shoulders and chest fit me perfectly, but the arms are too long which is not a problem for me. My husband who is also very tall can also fit the Oasis 200 just fine. I'm not sharing - I bought him his own.
I absolutely LOVE this shirt. I have another icebreaker thermal shirt which is Merino 300 and it is way too hot for day to day high intensity outdoor activities. I got this shirt as a gift, and in contrast I find the Merino 200 perfect as a base layer for my bike commute, snow-shoeing and backcountry skiing. I also love the small details of the black pine trees and lines. So much more fun than a plain white shirt and I assume will hide stains better. My favorite part of merino / icebreaker products is that even after a day of use and sweating I find the shirts do not smell (or at least not anywhere close to as bad as a synthetic gym shirt material).Overall highly recommend for people looking for a good base layer of good quality.
I LOVE this top. I bought it as my first pair of long underwear several years ago, but it is such a comfortable top that I wear it in my day to day as well. It's a little see-through across my breasts, but I have a large chest, and it just looks a little stretched. I have a lot of sensory problems, so finding shirts that look good, feel good, and are of a quality I'm happy buying is really difficult. This one fits the ticket! I'm back on the website now to buy more in different colors.I've had this for several years and while I try to wash on cold and airdry, I'm pretty sure I've put it through the drier at least once, and it's still fitting perfectly! My whole family got these for christmas a few years back as well- There's really nothing I could say badly about ... MoreI LOVE this top.

I ordered a new Oasis LS for women directly from Icebreaker. I washed it according to the instructions and was even more careful. Result: Despite meticulously following the care instructions (double net, 20C degrees washing, no enzymes, only other Icebreakers in the washing machine) the product broke.3 big holes. Icebreaker refused to exchange the product. I did not wear it for any sports before washing, and also not afterwards.Icebreaker claimed I damaged the product which was not true at all.Icebreaker: "as this happened due to the usage of the shoe"--> Making up lies about the customer!

I bought my first Icebreaker Merino 200 Oasis Long Sleeve Crewe thermal top at a hotel gift shop in New Zealand last February when I knew I needed another layer to feel warm in the chillier-than expected weather there. I wore that top every day for the 11 days of the trip. It was on me for hikes and boat rides and walks through town. Since then, I have purchased three more. I wear them for hiking, with pants and skirts for work, or for a night on the town. I almost never have to wash them unless I spill something on them, because they never develop an odor. Having always been sensitive to wool, I was worried they would itch, no matter how subtle, but that has not been the case. They are soft and comfortable. I am fit and like my clothes to be close-fitting, so I get ... MoreI bought my first Icebreaker Merino 200 Oasis Long Sleeve Crewe thermal top at a hotel gift shop in New Zealand last February when I knew I needed another layer to feel warm in the chillier-than expected weather there.

I'll keep my eyes open as Icebreaker brings out more colors, because I expect to be wearing these tops for many years and would like to buy them in additional colors.
I've been wearing icebreaker for 9 years since I did a thru-hike on the AT. These things are expensive but well worth the price. I afford 1/year and now own about 8 of them. They are very durable, very well stitched, soft, non-itchy (and I'm sensitive), lightweight but very warm. From November to March I'm always wearing one. HINT: buy one size larger than you usually are. Because these are wool, they will shrink a bit, even in cool water, and you don't want to ruin it that one time it accidentally gets washed in warm! These work best with a little space between you and it, not skin-tight. The sizes and colors are always spot-on.
