MERIWOOLMens Base Layer 100% Merino Wool Midweight 250g Half Zip Sweater for Men

Meriwool so far the only brand I've come across that not only comes close but equals the fit and finish of more expensive merino clothing brands. It has a ribbon around the inside of the neck for sturdiness and comfort, the fabric is woven just tightly enough not to snag, and it shows no signs of pilling, as some of the cheaper brands sometimes do. I'll be ordering another.

Keeps me warm

These are the most comfortable and best fitting thermal tops and bottoms. Within one week of receiving my first pair of tops and bottoms I ordered a second pair.The quality of the product is outstanding.

Besides holding quite a bit of sweat, it feels good and is warm for fall weather. That said, I'll get the lightweight base layer next time.

UPDATE: My warranty replacement top also quickly developed giant holes all over the place no matter how gently treated, hand-washed, and stored (while my other brands are fine; it's not moths). My brand new Meriwool beanie ALSO has similar holes. I'm done with this company; their products are too fragile. I advise everyone to pay a little more for quality name brands like Smartwool and Icebreaker.OLD REVIEW:I bought this top for use as a base layer on colder runs (under 20F) due to wool outperforming polyester in warmth, comfort, wicking, and smell. The medium fits my 5'11" 165lb body well, being almost but not quite skin tight, and with a perfect arm length. Love having the half-zip option as it makes regulating temperature while running that much easier.Unfortunately, I discovered a dime-sized hole in the top after a single wear, and I was outside of Amazon's 30-day return window having bought it earlier in summer. FORTUNATELY, Meriwool has a 1-year warranty, and they actually honored it instead of weaseling out of it, which earns major respect in my book and is the impetus for leaving this 5-star review. You simply need to send them a photo of the defect, your order number, a screenshot of the order, and then they'll provide you a RMA pdf form to fill out for the exchange. You pay return shipping, and that's it.While I was waiting for the exchange, I ordered a nearly identical half-zip from Meriwool's competition -- Smartwool -- at nearly double the price to compare. Turns out I actually prefer Meriwool's half-zip for two reasons besides just being a better value: 1) Meriwool is a tighter fit for sweat wicking vs Smartwool (also a medium), and 2) Meriwool's collar doesn't awkwardly flop around when unzipped like Smartwool's does. Will definitely be buying more in the future for casual wear vs only winter running.

Fits well, my husband is 150 ish pounds, about 5"10". He wears at least one of the many wool 1/4-1/2 zip sweaters every day in the cooler weather. These wash well, I use cool water, all natural detergent, no softener and I dry them by pulling them over the backs of our kitchen chairs. We have several MeriWool brand items and I've never had a problem with shrinking. No issues with odor on something that is worn frequently between washes.

Me gusta que sea un producto natural, de lana de oveja y que a la vez sea tecnológico, fineza del tejido y con diseño. Igual que se atrevan a poner colores.

I liked that it was cozy.
