As a skier, you often run into a big problem: getting all of your supplies from point A to point B. Skiing requires a lot of equipment, from goggles and gloves to clothing and more. Probably the most important piece of equipment (other than your skis, of course), is your boots. In order to take your ski boots with you, you need something to carry them in. What you need is the Best Ski Boot Bag.
TLDR: I’ve used the Kulkea Boot Trekker for 3 seasons, and it’s been a delight. It has a large capacity, nice handles, and is well constructed. I have the ski bag from Kulkea as well. They pair nicely for flying to your next ski destination.

1. Best Large Ski Boot Bag: Kulkea Boot Trekker
The 69-liter Kulkea Boot Trekker is the most innovative, high-quality, and technically featured boot bag on the market. There’s a lot going on here, but let me try to give you a little overview of some of the bag’s features.
First, it’s a compartmentalized solution, adding more space on the inside. Keeping helmets on the outside allows them to ventilate properly--plus what was once just a 69-liter bag suddenly feels much larger.
The front pocket is perfect for hand warmers, lip balm, and other small items. In the top pocket, you can put your face mask, balaclava, bandanna, or whatever you want right there. The front main compartment can easily hold a water bottle or goggles in a microfiber-lined pouch. Additionally, there is a very large top pocket for your ski pants, base layer, and even your jacket – all the big base layer items can fit right in here! Boots go in the sides, one in each pocket. They can also go in the back by just sliding in. The pockets are built so that the boots are ventilated while they’re in the bag. The Kulkea Boot Trekker also has what are called sock pockets that run down the side of each pocket, while the front of the bag includes storage areas for one glove on the left and one glove on the right.
The bag itself, made from a high six denier ballistic nylon, is made of the highest quality material, with only YKK zippers used. There’s a sternum strap that attaches to a hiking grade support system at the back and a heavy duty waist belt that is attached by Velcro, thereby making it removable if necessary. The bottom of the bag is fully lined with waterproof tarpaulin. Double grommets are included where the boot pockets are to assist with drainage.
There are many more awesome features we could share, but suffice to say that the Boot Trekker is by far the best bag in the market!
Conclusion
Looking for a massive boot bag to carry just about all of your ski equipment? If so, the Kulkea Boot Trekker is the bag for you. With 69 liters of total storage capacity, it can easily fit your boots, clothing, gloves, goggles, valuables, and more!
The dimensions of the bag are 18 x 14.5 x 18 inches, making it big enough for boots up to approximately a size 13.
Made out of durable yet lightweight polyester, it weighs in at just 4 pounds when empty, making it very easy to carry around. Water-resistant and equipped with drainage grommets, it ensures that water doesn’t settle inside.

General FAQ
What is the best heated boot bag?
All sorts of issues can crop up when you involve heat in the cold. Or electricity in the cold. This pick is a great bag that adds heat to your feet…err, boot.
Our favorite ski boot bag overall is the Kulkea Boot Trekker. The “best heated boot bag” is the Kulkea Thermal Trekker. The Thermal Trekker is nearly the same bag, with almost identical dimensions. It just adds heat! So you get the same quality bag, but with heat, and at a higher price point. You’ll pay nearly twice as much for this heated boot bag vs. the non-heated one.
You usually use a heated boot bag overnight, after a day skiing. Putting your frozen boots in the heated bag will dry them off. The next morning, you’ll have nice, dry, warm boots to start your ski day off! Warm boots are much easier to put on as well. Stay toasty, my friend!

Buyer’s Guide – Ski Boot Bags of 2021
While most ski boot bags look similar from a distance, upon closer examination, you can actually see that they’re all quite different. Before making a final purchase on one, you must take these things into consideration. They include the bag’s capacity, its storage options, its overall construction, and its overall carrying comfort.
Capacity
A boot bag is designed to fit quite a few pieces of skiing equipment. While obviously, it’s supposed to store your boots, it’s also meant to store clothes, valuables, gloves, and, in some cases, a helmet. Most ski boot bags range between 50 and 70 liters in volume. Make sure that all of your skiing equipment can fit in the bag before making a final purchase.
Storage Options
In terms of storage capabilities, not all ski boot bags are created equally. They possess different numbers and orientations of pockets and flaps, from valuables pockets to clothing pockets and more. Get an idea as to what you’re going to be storing in your bag so that you can decide how the pockets will accommodate your gear.
Construction
You’ll be taking your boot bag to a number of places, probably subjecting it to quite a bit of wear and tear. In order to withstand this wear and tear, your bag must possess top-notch construction quality. Most ski boot bags are made out of tough but lightweight polyester. Read online user reviews in order to get an idea as to each bag’s construction quality and durability.
Comfort
Depending on how you use it, you might have to carry your boot bag around with you quite a bit. The majority of these bags are equipped with shoulder straps so that you can wear them like backpacks. If you’re going to carry your bag around a lot, you must ensure that it’s going to feel comfortable on your back.
Taking a Ski Boot Bag on Airplanes
If you’re buying a boot bag, there’s a reasonably good chance that you’re planning on taking it with you during air travel. Before you do this, you should know that different airlines have different luggage size restrictions. Let’s review the luggage size limits of the biggest airlines in the United States, shall we?
Continental Airlines allows carry-on bags up to 51 inches in total length (length+width+height) and 40 pounds in total weight. For checked bags, this airline allows 62 inches in total length (length+width+height) and 50 pounds in total weight.
Delta Airlines allows carry-on bags up to 45 inches on total length (length+width+height) and 40 pounds in total weight. Like Continental, they allow checked bags up to 62 inches in total length and 50 pounds in total weight.
Southwest, United, and US Airways are a little stricter about their carry-on maximums. While their carry-on weight maximums are the same at 40 pounds, their lengths differ. Southwest allows carry-ons up to 24 x 16 x 10 inches, United allows carry-ons up to 22 x 14 x 9 inches, and US Airways also allows carry-ons up to 22 x 14 x 9 inches. All three of these airlines allow checked bags up to 62 total inches (length+width+height) and 50 pounds in total weight.
Conclusion
Skiing is fun, but lugging ski equipment around isn’t. However, that doesn’t mean that it has to be as difficult as possible. By purchasing a ski boot bag, you’ll enable yourself to carry your ski equipment around with as much ease as possible!
The two best ski boot bags currently on the market are the Transpack TRV Pro and the Kulkea Boot Trekker. Both bags possess tons of storage capacity and are extremely comfortable to carry. If you want ski equipment transport to be as simple as possible, these are the bags for you.

Tristen says
I am a skier on a low budget right now so the Athalon Everything seems like the best choice for me. I do have a big boot size though so I’m hoping it will still fit. I’m also not the strongest individual so I hope the bag doesn’t get too heavy.
Reed says
I love how the helmet holder part of the bag is on the outside of the Kulkea Boot Trekker. It makes it a lot easier to get your helmet in and out of quickly and without hassle. Plus, sometimes I like to switch my helmet up and they’re differently shaped so having a pocket might not work for all of them.
Trent says
I am a newbie to skiing and I totally didn’t even think about getting a bag to put my helmet and boots in for the drive up there and moving stuff around. I almost completely forgot it and we leave in a week. Since most of these are Amazon are they all eligible for the two-day shipping?
