Great fit, amazing material

Great fit, amazing material! I bought this but have not worn it until just a couple days ago, I have to say I love the fit & the way the fabric feels, really well-made!

Really Great Shirt

Received this shirt yesterday, and ran in it this morning. Very comfortable. It kept me warm, yet it is lightweight. I loved it so much I ordered another one.

Great extra layer for cold weather

The fit is great, Mercury material is very comfortable. Keeps me warm during cold weather runs/ workouts and breathes so well that is stays on.

Great running layer

Excellent running layer. Warm but lightweight. I wear a t-shirt underneath. On colder days (below 30 F), I'll wear a long sleeve t-shirt.

Fantastic addition to winter wardrobe

Super comfortable, fits perfect. I'm 5'11 and 170lb and the medium is a perfect fit. I wear a tshirt under and it keeps me warm. Super happy

Ideal!

Received the Mercury Quarter Zip and right out of the package the material(s) was soft on the inside and substantial on the outside, that I could not wait to try out on a run. However, proof was going to be on an actual run. I’ve taken this mid-layer top on two runs and I’m thinking this is one my favorites. It’s very comfortable, breathable, and insulating due to the make-up. Midwest winters are always fluctuating here and this piece is great for very low 30’s about 45 degrees depending on your layering.

Can I go out in it again, please🙏

It’s a bit awkward when an article of clothing shoves all its counterparts to the back of the closet. The Mercury quarter zip and I have been inseparable since it’s arrival. It’s smooth sleek surface has a great touch. I’ve found it a perfect top layer here in the Pacific Nortwest as it adds warmth and windbreaking ability. There are many shades of green out there and this is a favorite - in many ways. Thank you Janji.

Love it!

So nice! I’ve been looking for great winter running tops for our Minnesota winters and these so the job. The fabric is very soft and feels like it takes the bite out of the wind while also wicking sweat so I don’t get too cold or hot. Just right!

Everything I wanted

This Mercury material really is superb. I wore it on a recent run that started cold and it kept me cozy. Then the temperature quickly rose to a degree where I thought this top would get too warm. But it stayed breathable the whole time and I never felt overheated. Fit is also superb!
