    Romfh ChillFactor Sun Shirt is rated 3.3 out of 5 by 8.
    Rated 4 out of 5 by from Poor Fit I really liked the quality of this shirt, but the sizing was off. I am normally a size 4-6 depending on the item, the small was just a tad too small & the medium was very big, there was a big size difference between the small & medium, otherwise I loved the quality it is a mesh material which is perfect for those hot summers. If you can get the sizing right it may work for you. I imagine this top would hold up well, I would however wash on delicate cycle due to the mesh fabric to keep it nice.

    Rated 4 out of 5 by from Sizing off from last season I bought this shirt expecting it to not fit right per the other reviews. A small in this shirt is not the same as a small of the last seasons same shirt. The small in this new shirt is tighter fitting in the shoulders and in the arms. The medium is similar through the arms and shoulders to last season's small but the bust waist and length are a bit larger than last season's small. Also, the fabric is a bit lighter weight and not as silky feeling (which is fine- just a side note). So if you are comparing this fit to last years small, order up a size. If last years small was a bit too roomy for you, this season's small will fit fine. If you've never worn ROMF shirts and are fine with how a small fits in most other brands, you'll probably need a medium. The waterfall color is beautiful

    Rated 4 out of 5 by from Opposite problem with the fit! Mine is big! I normally wear a L in most shirts but equestrian brands tend to run small. In the TS icefil shirts I wear XL and it fits snugly but good, especially in the arms. After reading reviews that this runs small I figured I would need the XL in this as well. Its actually too big. The waist is ok but it is long, the shoulders and arms are baggy too. Its not terrible but its probably a size too big. They no longer have the color in L though so I'm just going to keep it because its still wearable and I want this color. Other than the weird sizing, the material of the shirt is super nice and cooling.

    Rated 2 out of 5 by from Runs very small When I opened the box I was surprised how small this shirt is. I am 5'7, 126lb. The shirt literally looks like Child size S, for 7-8 years old. I put it on. Fabric feels very pleasant for skin and stretchy but fit was funny, short and narrow in shoulders. Quality of the shirt is great! If you are very petite person you would love it.

    Rated 3 out of 5 by from Comfortable, but sizing off This shirt is very comfortable but it’s sizing is off. I usually wear 12/14 top, which is M/L, but I read reviews and many felt the sizing was very small. I ordered an XL and it still isn’t fitted for me. It is a little tighter than I like and is shorter, also. I gave 3 stars because it is comfy and cooling and is doable for me. I just wish it was sized more normally.

    Rated 2 out of 5 by from Would be wonderful in true adult sizes The fabric felt lovely. Slight chemical smell, but nothing that would not go away after a wash or two. However, the adult large (which I purchased) would not fit a friend of mine that is 5'2" and all of 100 pounds. It had both of us flumoxed searching for the label that stated it was a childs shirt. Alas, it was labeled as an adult large but there is no way any large adult would be able to wear this and be seen at the barn much less in public.

    Rated 2 out of 5 by from Very tight fit! This is an extremely fitted shirt. Sleeves were the perfect length but it was very tight and short in the body. If you are very slim for your height and don't mind not being able to tuck in the shirt, this is probably the shirt for you. Mesh fabric felt great and the color (topaz) was lovely.

    Rated 5 out of 5 by from Beautiful fitting and a feel good riding shirt I purchased this shirt for my daughter who is a professional rider and trainer of the Hunter/Jumper circuit. She is at the barn every day all day and wants protection from the sun and to keep cool. This shirt not only looks professional but feels great after a full day of riding, training and teaching.
