Materials
For multiple options of loading your pet inside, there are top and side entry options. The spring wire frame allows the south side of the carrier to be pushed down several inches. The carrier itself is made from nylon and features mesh windows and a removable faux lambskin liner. Also, locking zippers will prevent your animal from accidentally escaping.

Size and Dimensions
There are a few sizes you can choose from but the largest measures 19” x 11.75” x 11.5” (L x W x H). When needed to fit under a seat, the wireframe will push down several inches.

Comfort
Your pet is sure to stay comfortable while inside with mesh panels for ventilation and a soft and comfortable lambskin liner. To add a little convenience, there is a rear pocket where you can store all sorts of accessories such as leashes, bags, snacks. If you think your pet might need it, stuff it in the compartment.

Portability
For carrying purposes, there is a non-slip shoulder strap which features padded support and adjustability.

Overall
This is an ideal pet carrier for dogs and cats alike, although another opening on the end would have been a nice addition for dogs. There are even extra coloring options if you want to travel with your pet in style.

Materials
The entry choice is yours with a top, front and side opening available. As far as the overall construction, this is as good as it gets. Tightly woven materials provide a great amount of durability, strong steel bars easily lock into place, resilient mesh casing will not fray, and the zippers are heavy-duty.

Size and Dimensions
For the extra-large option, the carrier will measure 36” x 27” x 24”. If this is too large, there is a smaller option available.

Comfort
This crate is designed with your pet’s needs in mind. It is specifically designed to provide an optimal amount of breathability throughout all seasons, in addition to a soft liner.

With as large as this crate is, some storage compartments would have been nice. Although, there probably will be excess room in the carrier.

Portability
When your pet is not inside, this crate easily folds down for convenient storage. While carrying them, though, you can do so with the dual straps.

Overall
For larger pets, or pets who love to have their space, this may be one of the best options available for you. Past the size, it helps that the construction and design are top-notch with only a few flaws present.

Materials
This is built with an extra-tough design featuring tear-resistant mesh and polyester fabric. To prevent the carrier from sagging, there is a sturdy insert inside. All in the meanwhile, it is fitted with two seat belt buckles for the safest trip possible.

Size and Dimensions
The lone size option measures 17.5” x 10” x 11.9” and note that it is a little smaller than our other entries.

Comfort
There is a clear emphasis on comfort with mesh ventilation on the sides as well as two ultra-soft fleece pads. Even though your pet may be freaking out, they will be cozy.

To carry your pet’s accessories or any snacks, there are two pockets integrated into the carrier.

Portability
When taking your pet on an airplane, this carrier will easily fit underneath major airlines’ seats. In addition, a clip-on shoulder strap and padded hand strap provide you with multiple carrying options.

Overall
A special design flaw to note is that if your pet rolls over to the side of this carrier, it may tip over due to its nature. This may or may not be a concern for you but even if it is, do not let it overshadow the greatness here.

Materials
Besides its expandable nature, the wide frame on both sides adds terrific support to the carrier. In addition, both the doors have self-locking zippers for easy and safe access. This carrier features a cloth fabric, polyester lining, and mesh windows and a fleece bed for your animal.

Size and Dimensions
When not expanded, the largest version measures 19” x 12” x 12”. However, the width can expand to 33” providing excess room for your pets. Of course, there are also smaller options if you choose.

Comfort
Coming equipped with a soft fleece mat for comfort and a mesh-design for proper ventilation, in addition to the excess room when expanded, your pet will not have an uncomfortable ride.
There are pockets on the side that can store any small goods you have. Also, the excess room can be used to store any toys or items for your pet.

Portability
The nylon woven tape hand and shoulder strap deliver reliable and easy transport.

Overall
Clearly, the expandable nature of this carrier makes it stand out. While it could have been higher, no thanks to a few flaws, beggars cannot be choosers when it comes to consumer products.

Materials
Dual-entry points, at both the front and the top, allow for easy access and stress-free loading. In addition, the zippers on both the front and the top keep the entries secure.

Size and Dimensions
There are three different size options for you to select from including small, medium and large. For the large, it measures 19.7” x 10.2” x 11.2”.

Comfort
Both a fleece pet bed and base insert are included and both can be removed for cleaning. All four sides feature mesh ventilation to prevent overheating. Although, for cats, this can actually be a hindrance as they may get spooked with the lack of closure.

Just a standard pet carrier and no additional compartments are integrated for storage purposes.

Portability
If you plan on taking your pet with you to the airport, this is a great choice as the spring wire frame can be conformed to meet under-seat dimensions on most airlines. Plus, you can carry it with an adjustable shoulder strap for hands-free carrying.

Overall
Truthfully, there is not too much to gripe about here. However, looking at it with a different eye, nothing particularly stands out either. Due to the mass amount of exposure, though, this may be best suited for small dogs.

Materials
You can think of this pet carrier as another great piece of luggage in your collection. In fact, it’s actually made from luggage-grade nylon! Its durable design allows it to be used as a pet bed, a carrier, and a car seat, all at the same time.

The round zipper goes all the way around and the top of the Sleepypod dome can actually be taken off, making this a great animal bed for travel. There is also a vertical zipper on the dome, allowing you to easily access your pet.

Size and Dimensions
The Sleepypod is available in two different sizes. The mini is suitable for animals up to 7-pounds. The dimensions of the mini are 13” in diameter and 5” tall. The medium is suitable for animals up to 15-pounds. The dimensions are 17” in diameter and 6.5” tall.

Comfort
The inside of this carrier is quite luxurious for an animal. Seeing as how it doubles as a bed, it is understandable! The bed inside is made from plush polyester and can be removed and put in the washing machine. The mesh dome top allows your animal to receive great airflow and gives them a full view of the outside world.

Portability
The mini-version of this carrier fits under the seat of most airlines. The medium, however, is too big. When walking about with the carrier, there is a padded shoulder strap that can be attached to the dome for easy transport. There is also a top carrying handle if you prefer to carry the bed in your hands.

Overall
If you’re looking for a versatile piece that can be used every day, this is it. This carrier is available in ten different colors and has a unique style. It does come with a higher price, but for the three different products you receive in one, and the quality, we think it’s a great investment.

Materials
Petmate utilizes a plastic and steel construction for enhanced strength, safety, and visibility. With a two-door integration, it is also easy to get your pet in and out. The opening of the steel front door also has a secure latch to prevent escapes.

Size and Dimensions
The largest option measures 24.05” x 16.75” x 14.5”; although, there is a smaller option available if you do not need this much excess space.

Comfort
Rest assured, there are enough ventilation and visibility for your pet to be able to breathe and not feel claustrophobic. But, it accomplishes this in a way where your pet is not fearful of seeing too much. This carrier doesn't feature a cushioned bottom, but there is room to add a towel or favorite blanket.

This carrier is designed in a way that there are no storage compartments. If you wanted to, you could simply store the pet’s accessories inside the kennel.

Portability
While there may not be a shoulder strap, there is a durable carry handle located on top of the kennel. It is padded enough to not provide discomfort.

Overall
What is excellent about the design is the steel and plastic are as durable as it gets, but the amount of ventilation allows your pet to stay comfortable. The front door could have been a little easier to open and close, but it is not too big of a deal.

Materials
Not only are the top and the base firm for protection but they are also waterproof, as well. To prevent the cleverest of felines and canines from escaping, there is a security lock on the door zipper.

Size and Dimensions
This is suitable for small dogs and cats, but nothing overly-large. The dimensions read 17” x 13” x 14”.

Comfort
The two key features for your pet, breathability, and comfortability are present here with a padded mat on the floor and a see-through mesh door.

Unfortunately, nothing of note to speak of hearing. Honestly, it is probably not big enough to store anything inside with your pet.

Portability
While it is not in use, the soft sides can be folded down in a neat little package. When you need to carry your pet from one place to another, you can use the firm handle located on the top cover.

Overall
A clever design makes this pet carrier worth it alone, but the small flaws bring down the overall quality. Still, this is a great addition for anyone’s next trip with their beloved animal.

Materials
It is easy to get your pet inside with a top loading and side opening design. The carrier itself is made from Oxford fabric and mesh. A rigid panel is included to prevent an accidental collapse and auto-lock zipper sliders for security.

Size and Dimensions
With a medium size, this measures out 17” x 11” x 11”. Thus, making it ideal for puppies and medium-sized cats.

Comfort
To create a firm and sturdy bottom for your pet, a rigid cushion has been integrated. There is an insulated EPE insert that will provide your pet with extra-warmth in colder conditions. However, the designers kept it fairly simple in terms of extra storage, there is nothing of note to speak of.

Portability
The carrier can be firmly attached to your luggage and the strap makes it easy to carry. Plus, it can be secured in your car seat on long car rides. Other than that, it can be carried by its handles or shoulder strap.

Overall
This may not be everyone’s first choice as the lack of visibility could be a concern for both the animal and yourself. If you do not foresee any issues with this, then you should be all clear.

Materials
It is constructed from durable plastic that offers strength and security. The front door has a steel-wire and there is an additional opening at the top for double the entry options.

Also, the spring-loaded latch allows for smooth opening. But, the door mesh is a little flimsy and it may be beneficial to wire it to the poles.

Size and Dimensions
The larger size measures 22” x 14” x 13”, but there is an additional option for a slightly smaller variation.

Comfort
Sure, there are more comfortable bases out there but pet owners will take comfort in the amount of ventilation and visibility present for their animal. On the sides, top, and back of the crate, there are openings for air.

With this type of construction choice, do not expect too many options for storing pet accessories or snacks.

Portability
Being made from plastic and not fabric, it can’t fold up but the carry handle on the top does allow for easy transport.

Overall
It is not perfect, but it is hard to complain about the results. When you need to take your pet with you on a trip, this will make a great accomplice.
