PLEASE NOTE: The measurements on our size chart are very similar to most major clothing companies. However, we generally allow for a relaxed fit - geared for outdoor activity, travel or a casual outing. Pants, skirts, blouses and polo shirts have extra room for comfort and are not body hugging. 

When fitting jackets, cover-ups or any outerwear, our fit model is wearing the appropriate under layers that we would expect you to be wearing. You do not have to "size up" - we have done that for you.


Never try to measure yourself. Seek the help of a companion and use a soft tape measure.

  • Height: Stand in stocking feet, with feet together, back to the wall. Measure from top of head to the floor.
  • Arm: Bend arm to 90 degrees. Place hand on hip. Start at center of back of neck. Measure across the shoulder to the elbow and down to the wrist. Number of inches equals your sleeve length.
  • Bust/Chest: With the arms relaxed down at sides, measure fullest part of bust/chest, keeping tape parallel to floor.
  • Hip: Stand with heels together, keeping tape straight and parallel to the floor. Measure around fullest part.
  • Neck: Measure around base of the neck (the lowest point of the neck). Number of inches equals the neck size.
  • Inseam: Take a pair of pants that fits you well. Measure from the crotch seam to the bottom hem. Number of inches equal inseam length.
  • Rise: Start the tape at the center back waist, run the tape between your legs, pulling comfortably at the crotch and up your natural waist. Total measurement is your rise.
  • Waist: Measure around your waist, against your skin (not over your shirt or pants) at the height you normally wear your pants.
  • Head: Measure around your head, from the center of your forehead, keeping tape straight and parallel to the floor. Measure around fullest part.
Rated 5 out of 5 by from Perfect as a sun cover up! I bought and used this for a recent overseas trip. I was a bit skeptical that it would really be cool in the bright sun given the dark color. It was very cool - I did not get hot at all. I suppose the material and the underarm ventilation keep it cool. One drawback is that it was the jacket I had also counted on for any cool days we encountered. We had a cloudy day in the 50s with high winds. It did not keep me warm then!

Rated 5 out of 5 by from This is my everyday jacket I'm pretty sure I wear this little jacket at least 6 times a week; to the gym, to the store, running errands, etc. I just ordered the white with black trim and I love it. Because I use it so much, it justifies the price for me. I have the black jacket and the white, and they are incredibly versatile. I noticed the new white one has slighy longer arms so that was a good fix Coolibar. I am 5'1" about 134 lbs athletic build and I like how the xs size fits me.

Rated 3 out of 5 by from Almost all right As others have mentioned, the Seaside Hoodie is too short in back. I am among those who would prefer to have her derrière under wraps. This hoodie measured 24 inches at center back. Your V-neck T-shirt measures 26.5 inches at center back, and a fleece vest I have, from a well-known manufacturer, also measures 26.5 inches. I tried your Swing Top, which measured 31 inches in back, and which I, along with other customers, deemed too long. I am returning these items, to await hoped-for revisions to Coolibar’s designs.

Rated 5 out of 5 by from Perfect sizing, lightweight for summer I was so pleased to se that the sizing on this was perfect! I was looking for something with high SPF protection that won't be hot to wear outside in the summer. This is exactly what I was looking for. I can't wait for the snow to melt and temperatures to warm up so I can wear it outside. I wish I had it in other colours, too.

Rated 5 out of 5 by from I love this jacket! I already had four of these jackets, but hesitated to buy more because of the reviews complaining of short sleeves. I took a chance, hoping that the problem had been fixed. Good news! The sleeve issue has been resolved! The jacket fits perfectly and the sleeves fit exactly as they do on the model. I love the weight of this jacket, it is comfortable in 90+ degree weather and never sticks to my skin. The pockets are a generous size - I can zip up my cell phone, keys, etc. when riding roller coasters with my son. The large inside pockets are big enough to contain my Kindle. This jacket is perfect! My only suggestion is to add more color choices.

Rated 5 out of 5 by from Favorite Sunblock Jacket with great features! Since I am not able to be in the sun at all, have purchased many of these jackets for over 3 years. Love the lightweight fabric for Florida weather. Hood ideal for full coverage protection. Sleeves fit fine. Never had any problems with the zippers. Please don't ever eliminate this jacket from your catalog.

Rated 3 out of 5 by from Sleeves are too short! I love the fabric....but I bought this jacket for myself and my husband, but the sleeves are short. I had to go up a size for the arms to fit, but now the body is large. Haven't had a chance to wear yet, so cant comment on the zippers. I hope they are okay.

Rated 1 out of 5 by from So disappointed So disappointed in this jacket. Sleeves too short and I am a short person with short arms. Zippers are terrible. Zipper on right side pocket is stuck closed. Husband can't even get it to open. Left side pocket zipper keeps getting stuck. When I pay this kind of money for a jacket, I expect it to be perfectly made. I have a white jacket like it that I purchased a few years ago that I love. I expected the same quality with this new jacket. Very disappointed and will look at other places for sun prevention clothing.

Rated 1 out of 5 by from Terrible zippers I bought two of these jackets for a trip. Having purchased them before, I didn't think to try them out before traveling. The two-way zippers are terrible! They consistently get stuck when trying to zip them up from the bottom. Very frustrating. And yes, the sleeves are short. I would not recommend this jacket, which is unfortunate because I have loved other Coolibar lightweight jackets!

Rated 1 out of 5 by from Sleeves way too SHORT !! I got this jacket because it's the perfect weight and has all the features I want but I regret getting it because for some reason they shortened the sleeves and it looks silly. ---Do not get this jacket --- I will have to wear my sun sleeves in addition to the jacket to get proper protection ... that doesn't make much sense. No idea why they changed something that was fine & by the reviews I'm not the only person who thinks this way. Buy something else !

Rated 1 out of 5 by from Frustrating The sleeves are too short and trying to get the zipper up will make you want to kill yourself. Ok, I'm being dramatic but, seriously, the zipper is so effing hard to zip up. Arrgggg!!!

Rated 5 out of 5 by from Love that the sleeves are shorter! Finally , a jacket I don't have to roll the sleeves up with!!!! I am short so I just factor in the cost of having the sleeves shorten , or have pants hemmed ! How all I ask it that y'all make this jacket in a pretty summer pink !!

Rated 2 out of 5 by from Why did they shorten the arms? I've been wearing coolibar full zip hoodies for years. Size L has fit fine. But now the sleeves are too short on my latest purchase. I called Customer Service while said they shortened the sleeves by one inch. Why? Did women's arms get shorter? Sleeves are too short and I'm now getting more sun exposure than I should.

Rated 4 out of 5 by from Sleeves too short It feels great, just like every other coolibar jacket I've owned...but i don't know why the sleeves are so short. When I'm driving with the jacket and sun gloves on, the sleeves keep rolling so far back that I'll actually have to wear arm sleeves in addition to sun gloves if I want my arm fully covered.

Rated 1 out of 5 by from Still looking for something to cover up my arms. I bought this jacket two weeks ago to wear for base ball games. I usually wear a size L so chose the size XL so it would cover up more. The jacket was large. My complaint is with the length of the sleeves. They are way to short, fitting 4 inches above my wrists. Sun protecting blouses and jackets usually come with longer sleeves to cover top of hands. I also thought for the price it would be made a little bit better. I have lupus and need to stay covered up in the sun. I sure don't want to miss my grandson's base ball games either. The color was not pretty either wish I picked the white one now. I spend a lot of money at Coolibar.

Rated 2 out of 5 by from short sleeves I bought this jacket for an upcoming trip. I usually wear a size 8 so chose the size medium. The jacket was smaller than expected, but fit. My complaint is with the length of the sleeves. They are short, fitting just above my wrists. Sun protecting blouses and jackets usually come with longer sleeves to cover top of hands. I also thought the price was a little steep.

Rated 5 out of 5 by from Terrific Jacket - but I need packing instructions! I wear this jacket in high sun. It keeps me protected, and I'm no warmer/hotter than if I didn't have it on. Very nice. But I can't figure out how to pack the jacket in the left pocket, as described. Sure would love a video!

Rated 5 out of 5 by from My go to "in the sun" jacket! This jacket is fairly true to size. I bought an X-Large, but could have used Large. I did this because I like a looser fit and sometimes like to wear bulky close underneath. I expect to wear this jacket spring through fall. I have an autoimmune disease that causes me to be sun sensitive and some days I need more protection than sunscreen and extra sleeves provide. The hood ties down comfortably to give me extra protection covering a good portion of my forehead, cheeks and neck. This jacket is a life saver! I keep it folded into it's own pocket, place it in my purse or backpack and off I go. I highly recommend it!!!!
