I live in MN and was looking for a baselayer for winter running. THIS IS PERFECT! I want another one so I can rotate and not do laundry since this is the only shirt I want to wear this winter. Perfect!

Awesome base layer, doesn't stink

The major pro for wool is that it hides BO stank. The con is that it can be itchy. I found the wazzie wool long sleeve to be less itchy that other wool or wool-blend fabrics, but it definitely isn't as soft as the Lux fabric. However, because of its ability to hide stank, it is my go-to shirt when traveling, camping or backpacking. I didn't shower for 10 days this summer while backpacking and I wore this shirt every.single.day without washing it. It only smelled faintly, barely unpleasant by the very end. I also run in this shirt and wear it around town, typically 5-6 times without washing, compared to Lux fabric which I wash every 1-2 times. I love the blue color and design. Like others have mentioned, the sleeves run a big long. If you're too busy to do laundry- wazzie wool is for you!

Beautiful top, interesting smell

I was so excited to grab this top on sale in the Oba Blue. It is beautiful and fits really well. I had a really hard time deciding between the 4 and 6 but went with the 4 and it fits great although I lean more toward the 6 in the sizing chart - 5'6", 135-140 depending, 34-29-38 measurements. I did read one review about the smell but wrote it off. No smell when I received it but I threw it in the wash on cold and when I took it out - WHOA! My first reaction was kitty litter, then perm (yes I had my share of perms in the 80's...). I hung it out all day to dry hoping the fresh air will help. I really love this top in every way but TBD on the smell issue. As an aside I have owned many wool items including Smartwool, Ibex and Icebreaker and never experienced this before.

Be Careful - this isn't spandex!

Love this top, and wear it as a base layer almost all the time - however I had a similar experience to one other reviewer in that I was out camping and grabbed a sleeve to pull it off, and ripped a 3 inch tear. It's currently at the cleaners being repaired, but you have to treat this more gently that your other long-sleeved tops. Sleeves can feel a bit long but it's a great fit and versatile piece.

second chance at love

Wool-it's a risk sometimes. At first try-on I lasted about 15minutes before I declared itchmania. However, I just loved the look of this and in the winter it just makes sense to don wool items. So I retried this little gem and was relieved that it remained on for a significant duration. Nothing compares to the Lux fabric, but this shirt is a fantastic layer. It's perfect under the Quill jacket or vest or solo on a not as freezing day. I may have even worn it with a little skirt and tights because, winter "dress up" as a runner and all......

Great Winter Layer!

Tried this for the first cold Buffalo run yesterday and I was astounded at how much warmth I got from this shirt. It's soft and light but kept me warmer than a lot of heavier winter running shirts.

great, but no lasting power!

I loved the shirt, I loved it completely...for a month. It was a wonderful baselayer for hiking, and quickly became my favorite winter running layer. I cared for it with caution, I'm a knitter, so I know how to care for wool. Last Saturday I wore it for a trail race, and an hour in when I started to warm up, I hiked up the sleeves, and ripped a nice quarter sized hole in the cuff. Trail running can be rough on gear, but I definitely don't expect clothing to not hold up to pulling up the sleeves!

too long

I loved the feel but unfortunately it was too long in the sleeves and just too long overall. I'm 5'0" weigh 115 and normally wear a 4. The 4 didn't work for me. Too bad, I really wanted to love this top!

Hi Pamela, sorry to hear that the Wazzie Wool Base Layer didn't work for you! You might like the Spring Wazzie Wool Taper Sweater - it features a shorter body length and 3/4 sleeves.

Pleasantly surprised

I was hesitant to purchase a piece of Wazzie wool because for all I've heard about the "magic" of wool for athletic wear, I have never had great experiences. In fact, and I know this will make me sound crazy, I have never been able to get past the distinctive smell of wool. I don't care if it resists the stink of my sweat if I can't stand the smell of the shirt in the first place! I was very pleasantly surprised to find that this shirt is wonderful in every way. The fabric is substantial, but also lightweight and comfortable. There is no "wool" smell whatsoever, even wet out of the washer. It wicks like a champ, and keeps you warm without feeling at all stifling. I've also appreciated that it has handled being thrown into the family laundry with no issues, retaining the quality of fabric and shape through many normal wash/dry cycles. (I do not have time to wash my running clothes separately.) While the cost is substantial enough to give pause for thought, it is definitely worth it to have one of these base layers in rotation.

can't take it off

I was skeptical about this shirt because I am sensitive to wool and cashmere. Everything makes me itch! What a sweet surprise when I slipped this baby on and it felt like butter. The fit and fabric are both perfect. I am embarrassed to say that i didn't take this shirt off all weekend...and that is before I actually ran in it. The Wazzie Wool kept me warm in a rainy 30 something run and is nice enough for Friday office casual days. I want it in all colors.

Oiselle at its best!!

This is possibly my favorite Oiselle purchase ever, and that is saying a lot. I would buy it in every color if I could afford to! I love to wear it so much in regular life that it is hard for me to want to get it sweaty, but actually even when I do run in it it does not get stinky (magical fabric!) and I have been guilty of wearing it, unwashed, for regular life again :) I'm usually between S and XS and S was perfect for me in this.

I have long been a lover of wool for training - and these tops pass the test with flying colours! Running, xc skiing, winter riding - they rock! Super comfy and soft, and well fitting. Sleeves are nice and long and the pattern makes it fun! I'm often a small in most Oiselle, and small fit perfect. I did order the medium in the wazzie sweatshirt for a slightly looser fit, and it's perfect!

Perfect base layer

I was a little hesitant to buy a wool base layer, but this has exceeded my expectations (I've just ordered a second one). It keeps me warm and dry, and is really soft. I was pleasantly surprised, too, after I wore it for a second run without having a chance to wash it, that it smelled much better than the (non-wool) layer I wore over it. I agree with others that if you're on the border between sizes to size down unless you want a loose fit (I'm usually S/M in a top and chose small - it fits just the way I like it). I've dried it on a low setting and also line-dried it - it came out of the drier fine. I won't usually do that, but it's a good option when short on time.

Just. Wow.

I've been into Merino for what feels like ages. I love Smartwool socks, and I've got casual wear tops from a couple different brands, all generally considered high-end. The Wazzie Wool blows them all away. It's by far the softest of the lot. It is very warm but also breathes well, so no overheating. It is expensive but worth every penny. Washes well too (I use cold cycle and line-dry). I've found it to fit the same as the Wazelle LS & the Flyte LS. The arms are snug but stretchy so not constricting. It's super-flattering.

I'm in love

I love all things wool and this baselayer is no exception! Super soft, lightweight, love the geo detailing. I have the geo red and it's amazing. I wore it skiing one day and running the next and it felt great next to skin! In my opinion it runs a little big, which I don't mind. I usually wear a small or medium in Oiselle tops and am keeping the small in this style. I probably could have gone down to XS but I like my tops to fit a touch loose.
