Outdoor Research Women’s Oasis Sun Sombrero (Review 2021)

Outdoor Research Women’s Oasis Sun Sombrero

We regarded the Oasis Sun Sombrero by Outdoor Research as the best sun hat for women in the list of the best sun hats that we have reviewed. Apart from the stylish looks, this is also a reliable hat to shield you from UV rays with its UPF 50 rating. The hard wide brim can cover you to prevent the winds and sunlight from ambushing you in the midst of your adventure.

What we don’t recommend is the structure of the hat’s body which obstructs the comfort and breathability features. The head size is limited and there are no holes or mesh panels on the hat but the fabric is made from nylon and polyester materials which are known to be breathable.

Let’s further discuss the features and performance of this sun hat based on the following topics: comfort, breathability, protection, durability, and value for money. Keep reading our review to know whether this equipment is good for you or not.


Sun hats are one of the most crucial components of anyone’s hiking apparel. Whether you’re effortlessly hiking your favorite trail or trekking a challenging mountain, using protective equipment is very important. We listed our top hat picks in our “Best Hiking Sun Hat” article to help you find the perfect hat for you. 



There are many types of outdoor hats for your camping needs. One type of hat that we are going to review is more focused on sun protection and this is the Outdoor Research Women’s Oasis Sun Sombrero. This equipment made its way from our selection of sun protection hats however, there are some drawbacks that we need you to comprehend first.

Before you are able to arrive at this review, you may have read the manufacturer’s description that this is a comfortable hat. Let’s say that there may be users who are satisfied with the fit of this hat however, we discovered that the capacity to cater to head sizes is limited. That’s why we suggest you should test this hat first before buying it.

From the perspective of our campers, who have tested the small version, they revealed that it is uncomfortable to wear for a lengthy amount of time. It feels that the inner parts of the hat are so tight that resulted in the formation of marks on their foreheads.

So, in this condition, if you are apprehensive about the size of this hat, it’s better to measure your head size. That method can help you in choosing the best fit for you.

But if you are looking to assure comfort, you can check the features of Sunday Afternoons Unisex Ultra-Adventure Hat. Almost all of our testers left positive feedback after they used it. That does not make the Oasis Sun Sombrero inferior. All you need to do is find the correct size for your head.

In this area of the Oasis Sun Sombrero, we can say that it will leave the users unimpressed. If you judge the look of this hat, you can see that there are no mesh panels or any elements for breathability. That will leave your head hot and sweaty.

Although there are no visible breathable features you can spot in this hat, the manufacturer, Outdoor Research has designed it with a sweatband inside the hat but we presumed that this will not contest the drawback on its breathability aspects.

The fabric used to make this hat is nylon and polyester. These materials are considered to bear breathable texture which may lower the tension on the no ventilation sides of the hat. That is somewhat a good thing to support this feature.

On the other hand, there are also attributes in this hat that we commend and this is the One-Handed Drawcord Adjustment and Removable Chin Cord. It allows you to tighten the hat to prevent it from falling if ever a strong wind blows. This is a common feature that outdoor hats possess.

Another thing we would like to highlight is the inability of Oasis Sun Sombrero to be packed. This is due to the huge and stiff brim wherein it is hard to fold it gradually however the drawstring on your chin can also be used to hang this hat on your neck.


Nobody wants to experience a quick day hike trip with excessive weight on their shoulders. Imagine the heavy load and muscle pains you’ll go through by the time you get back home. To help you avoid this situation, read our article to learn how to pack for a day hike.



This hat has redeemed its performance in this section of features. We may have found some downside on the breathability and comfort areas but in terms of protection, the Oasis Sun Sombrero can shield you in many conditions. How big is this sombrero to make sure it can cover you properly under the sun?

The brim of Oasis has a measurement of 3.25 inches on the front while 4.5 inches on the rear part. If you notice the front and back brims have different sizes. This is due to the purpose of the hat to protect the nape area of your neck.

The size of the brim feels really big because of the hard design. The manufacturer called this feature a Floating Foam-Stiffened Brim. With such, you can trust this to protect you from the harmful effects of direct sunlight and winds.

Aside from the wide brim, a certain fabric should have ultraviolet(UV) protection for complete protection. Similar to Sunday Afternoons Unisex Ultra-Adventure Hat, this has also a UPF (Ultraviolet Protection Factor) 50 rating. This rate is already considered as excellent protection.

The figure of this hat looks stylish and it can definitely defend your head and neck from UV rays. No what kind of activities you are planning to do outside, this hat can provide you admirable protection.



Outdoor Research Women’s Oasis Sun Sombrero showed off its sturdiness when our campers tested it during their camping. The stiff structure of its brim is what makes the whole body dependable. Let’s scrutinize the other elements that the manufacturer placed in this outdoor hat.

Oasis weights for about 3.4 ounces which are less than a pound. We consider this also as a lightweight gear that is best to carry around. The materials used to manufacture this hat is 89 percent nylon and 11 percent polyester. Its main shell is a double weave ripstop.

The materials that Outdoor Research combined are more than enough to protect you with a great foundation. Some hats have the best features on other grounds but not on protection and durability aspects. Maybe this is the answer to your search for a potential outdoor hat with defense from the sun.

Value For Money

Our opinion will be based on the experience and comments from our hikers and campers. If we collate them, we can conclude that the price is quite expensive if you level to the features it can provide.

As we have mentioned, comfort and breathability are the downsides of this hat’s body. Those features are the key points of the outdoor hat that should be given some focus. What we mean is that there are numerous hats that can give you more of these attributes at a cheaper price.



Even if we found some disadvantages, we listed the Oasis Sun Sombrero as the best sun hat for women. We can see that Outdoor Research would like to highlight the sun protection features which are also similar to other outdoor hats.

There may be other types of sun hats that give attention to all sides of specs however, they are not that excellent.  So if you are going to the beach, hiking, fishing, camping, boating, or any other activities, this hat can accompany you and shield you from several situations.
