MERIWOOL Mens Base Layer 100% Merino Wool Heavyweight 400g Half Zip Sweater for Men

I love this half zip and just about everything from Meriwool. I live in Minneapolis where it’s bitter cold. I toss the half zip over their 250g base layer when it’s 20 degrees out and cold no more!Seems durable. I hand wash it with Eucalan wool wash.As another reviewer mentioned, the collar folds down when zipped down. I prefer this as it gives this a more relaxed fit.Pros:- I’m close to 5’10”, 170lbs. Fits as expected (purchased a Medium). It’s not skin tight so you can wear this on it’s own or over a shirt (which was my intention). Some can argue it’s a bit long, like many of Meriwool’s clothing, as it hangs about 6” below my waist....but I like the length.- Warm. I’ve only experienced this zip in the winter so it’s perfect over a base layer when it’s 20 degrees out :). When it’s 40 degrees, it’s great on its own.Cons:- The only minor gripe I have is that it “pills” up and collects fibers (or dog hair). This doesn’t bother me much but if you wear it a bunch before a wash, which I do, then you may need to take a lint brush to it on occasion.Overall, love it!

Excellent product. Super soft, warm, slightly itchy but that is true with any wool or merino wool product. Fits perfect. I am 5’11”, 175 lbs, ordered medium

I like my meriwool products they seem to be on the less durable side of the wool products. Probably should have sized down to a medium, arms are a bit long might try and shrink it a bit.

Incredible sweater for a great price when you can find one that fits you.I'm a pretty standard Large (43 inch chest/33" sleeve/5'9"/fit) and when I purchased a size L 250gram top, it was skin tight. I ended up donating it and buying an XL that was super baggy (but cozy, so I kept it). I figured the sizing might be weird, so I tried again and got another L 250 gram top. This one was much better, but still snug. Then it came time to buy this gorgeous layer. 400 grams of merino wool love. Not having confidence in the sizing, I ordered two, one in L, one in XL. I tried the L on and it was larger than the XL 250 top. The sleeves alone were for an orangutan. I didn't even try the XL on. I returned those two and ordered the M, which is a split in size between my L and XL 250 gram tops. I'm keeping it.About the sweater. Soft, thick, luxurious merino wool. Imagine a super thick wool thermal. Compares very favorably (with the exception of the sizing issues) to the Sm@rt Wool products. Good stitching, Wicked long sleeves. I'm a 33 sleeve in a dress shirt and you could probably fit comfortably in this medium sweater if you have 36 or 37 inch sleeve.I suspect I will live in this sweater through the winter, both on and off the mountain.Good luck.

We are convinced I may soon become a spokesperson for this brand. I hated wool against my skin hated it on me. But lost my thyroid and soon ran cold a lot. These clothes are comfy, warm yet let my skin breathe. This particular one I got because I needed to bump up my layer for kayaking in the winter under my farmer John wetsuit. Today in 30 degree weather I was nice and warm out there.

This is a great shirt to wear by itself or a part of a layer idea.

I was really on the fence with my sizing choice. I’m 5’11” 200lbs. I’m always in between Large and XL. Smartwool tops I wear XL. LL Bean I wear Large. I have broad shoulders and an overall tall slender build. I went with XL as I wanted room for another base layer and prefer to wear this as a sweater. The arms are probably 2” too long. I will probably hem them. For now I just fold back inside the sleeve to test. The weight is nice. More substantial than the base layers. Definitely a sweatshirt/light sweater type of weight. I’m happy with my size choice as I don’t won’t to feel constricted in my mid section. The long sleeves aren’t bothersome even if not folded. I ordered another color in the same XL after trying the first one I received. Great product.

This is a great second layer in my fishing gear. Thin wicking layer first, next this sweater with a vest in the fall or a puffy over the top and a shell in the winter. I’ll be grabbing a second one to keep them rotating.

The garment is of excellent quality and workmanship. However, the weight is not 400g it is 350g. Over the next several years, I will be able to judge my MERIWOOL heavy sweater. I liked the first purchase so much I purchased 2 more.

Body and arm fits much more comfortably than the 320g weight shirt from Meriwool, however the neck opening is gapingly large. Zipped all the way up the collar stands erect around my head almost in front my chin, I felt like Auron from Final Fantasy X.
