High quality base layer with lots of great features!
Received free product
This is a really nice midweight layer with good warmth to weight ratio and great features. Comparable to other more expensive brands! The side stitching makes the fit flattering (I did size up from Small to Medium so it wouldn’t be as fitted), there are thumb holes to keep the sleeves down, and there’s a bit of fabric around where the zipper stops at the top to guard against scratching your neck or chin. I also appreciate the generous sleeve length since I have long arms. I’ve used this on a few runs and hikes so far, and it’s been breathable and sweat wicking. The half zip is also nice for venting. I also love the color and have been wearing it as an every day piece, even when I’m not exercising!

Business casual hiking shirt for your next indoor or outdoor adventure!
Received free product
Long sleeve quarter zips are an essential part of my wardrobe - outside and inside! This long sleeve is very unassuming. Even though it is primarily polyester with some spandex, it feels and looks like a shirt made primarily with natural fibers! I like my clothes to fit more ‘relaxed’ so I got this in XL (5’9”, 178lbs) and the fit is perfect! Arms and body length are great and to top off it has well placed thumb holes! Wore it a few times in cool Wisconsin fall days walking the dogs and visiting WI Sheep & Wool Festival. Warmth was good by itself at low 60s. When in 50s, needed another layer it as it is pretty thin. It is a nice teal color and I could totally get away with wearing this at work. I’ll be getting more colors!

Versatile and core piece
Received free product
This top is super versatile and while I only wore it as a single layer, I can see myself using it as a base layer in the colder months. It’s lightweight and comfortable, with just a little bit of stretch. I also love the thumb holes that are usable but discreet.

Soft and comfortable, fits close but not tight.
Yes , I recommend this product
Very soft, comfortable long john top. Love the quarter zip neckline that doesn’t flatten my nose trying to put it on. Also looks more like a regular shirt you could wear to apres ski than the crew neck kind. Fits true to size. For reference, I am 5’8”, 149 lbs , chest 36”, and I got Medium. The arms are actually long enough for me, which is unusual, and there are thumb holes (although I confess I have never understood the point of those.)
