Temperature Regulation 

The most important feature about any cooler is how well it retains the temperature inside of the housing. Yeti coolers are known for their exceptional temperature regulation ability thanks to their unique design and the materials from which they are made. Both the Tundra 35 and 45 have the ability to keep your food, drinks, and other consumable items either hot or cold for a period of around 5-7 days with other high-end models and configurations being able to keep your items cool for approximately 10 days in total.

Both of these coolers do not vary much in terms of these factors however they will vary in terms of the overall amount of stuff that you can store inside of any given model and how easy they are to carry. This incredible amount of cooling power is only possible thanks to the unique material used inside of the Yeti coolers which insulates the temperature at a very efficient rate making it easier for you to stay out on your outdoor trips for extended periods of time. 

The Tundra 45 can hold about 34 pounds of ice while the 35 has a maximum capacity of about 20 pounds of ice which is more than enough if you plan on staying on your outdoor exploration or trip for a short time. The larger ice capacity is perfect for those who have large families along with them out in the wild or for those that are packing a large supply for a multi-day trip. 

The rated storage capacity makes it easy for you to ensure that you have enough food and drinks on your trips that last for more than 2 days which is why it is a wildly popular cooler with many people.

Both the Tundra 35 and 45 come with two completely different weight classes making them more optimal for certain classes of hikers and outdoor enthusiasts.

If you have a lot of people going on your camping or outdoor exploration trip, the weight may not be that important since you have a lot of assistance in terms of carrying the cooler. For those smaller outdoor trips and adventures, you will want to choose the lightest model to ensure that you’ll be able to carry it with you where you need is most. 

Size & Dimensions 

Aside from weight and storage capacity, the overall sizes and set dimensions of your chosen Yeti cooler will also play a very important role in helping you determine which model is right for your specific needs. the 35 is only about 4 inches shorter than the 45 model which means that all of the other dimensions are identical in terms of the width and height. That extra 4 inches may not seem like a drastic difference however the increase in length is very visible in terms of the amount of food that can be stored in the 45 as opposed to the 35 models. 

The 35 model is more of a cube shape while the 45 is in more of a rectangular shape which also gives you more access to food storage space. This elongated design will allow you to store and preserve wine bottles while on the go which is why the 45 models are recommended for those that are bringing a lot of food on their outdoors trip.
