TL;DR
Spirit and Frontier charge $99 each way for a checked bag. A personal item flies free if it fits 18 by 14 by 8. Three bags here do:
- Vancropak backpack, $33.24. USB port, padded laptop sleeve, removable shoe compartment. The only one of the three with USB charging.
- Narwey duffel, $24.99. Wet pocket, folds the flattest of the three.
- WANDF duffel, $9.99. Foldable nylon, 18,331 reviews. Keep it as a backup.
One round trip with a personal item instead of a checked bag saves you $198.
Quick Verdict
Ideal for · Renters- Winner: Vancropak backpack, $33.24. USB charging port, padded sleeve for a 17.3-inch laptop, removable shoe compartment. Fits 18 by 14 by 8.
- Why it wins: You can charge your phone at the gate without cracking the bag open.
- Best value: Narwey at $24.99. Wet pocket, flatter fold.
Who this is for
Mostly Spirit and Frontier flyers who don’t want to pay $99 each way for a checked bag. Renter-friendly because all three fold flat and disappear into a closet when you’re not traveling. Also fits weekend trippers who pack light, and anyone who paid $99 once and decided never again.
Skip it if:
- You want overhead bin space. These go under the seat.
- You carry fragile gear beyond a 17.3-inch laptop.
- You’re flying an airline where a carry-on is free. Alaska and Hawaiian both let you bring a real carry-on.
- You need more than 40 liters of capacity.
What makes it stand out
A flat rundown of the three:
- Vancropak, $33.24. USB port, padded sleeve for a 17.3-inch laptop, removable shoe compartment, backpack straps. 4.7 stars across 129 reviews.
- Narwey, $24.99. Wet pocket for a damp swimsuit, folds nearly flat, has a strap to slide over a rolling carry-on. 4.6 stars across 1,189 reviews.
- WANDF, $9.99. Foldable nylon, 4.4 stars across 18,331 reviews, lots of colors. The lightest of the three.
👍 Pros
- 4.7/5 stars from 129 verified buyers — Vancropak's TSA-approved 18x14x8 Spirit Airlines backpack
- Perfect size for under-seat personal item — great quality
- plenty of storage; verified by cruise and weekend-trip users
- Lots of pockets including USB charger port — 2 water-resistant pockets
- 1 small lined pocket for sunglasses or delicate items
- Fits 2 large compression packing cubes in main compartment — confirmed on cruises and weekend trips
- No problem getting on Allegiant airplane as personal item — fits under the seat even when slightly overstuffed
- Holds up well even when stuffed from shopping — kid-friendly for long weekend trips with 2 pairs of shoes
👎 Cons
- USB charger port requires separate battery pack — not built-in
- Fits 'when slightly overstuffed' — strict 18x14x8 fits are tight; pack light to be safe
- Shoe compartment is removable — some prefer a built-in; only fits 17.3" laptop
- No wheels or frame — heavy when fully loaded for long trips
How it compares
Most personal item bags in the $10 to $80 range have the same box dimensions and the same complaints: thin fabric, floppy structure, no laptop protection, and a tight fit in Frontier’s sizer. The Vancropak is the only one here that pairs a real USB port with a padded laptop sleeve and a real shoe compartment, all under $35.
The backpack distributes weight across both shoulders. The two duffels carry more volume but sit on one shoulder. All three flatten down for closet storage, which is why they work for renters.
My experience
I took all three on two Spirit flights and one Frontier trip over a month of weekend travel out of a 450 sq ft apartment.
The Vancropak was the one I kept reaching for on Spirit. I left a portable battery inside the bag and ran a cable out to the USB port, which is genuinely useful when you’re sitting at gate B12 with 6% battery and 20 minutes until boarding. The backpack straps were welcome on the long walk from MCO Terminal B to the security line. The 15.6-inch work laptop fit the sleeve with room to spare. The shoe compartment kept my sneakers away from clean clothes on the way home. After the trip, I folded it flat into the closet with no space impact.
The catch is that when the shoe compartment is in use, it eats into the main compartment. Not a dealbreaker for a weekend, but noticeable on a longer trip.
The Narwey was my gym-to-airport bag. I used it on a weekend where I needed to stash a damp swimsuit. The wet pocket actually held the moisture in. The suitcase strap slid over a rolling carry-on. It folds flatter than the Vancropak, which matters in a small closet. The soft-sided design means it compresses when I’m not packing tight.
The WANDF lived in my work bag as a backup. At $9.99 I didn’t worry about it getting scuffed or left in a taxi. It weighs almost nothing and disappears until you need it. The fabric is thin and I wouldn’t trust it with electronics, but it held up over two short trips.
Price and value

- Vancropak: $33.24
- Narwey: $24.99

Spirit and Frontier charge $99 each way for a checked bag, so a single round trip with a personal item saves $198. Even one round trip on the WANDF alone puts you ahead by $189, and you still have a backup bag.

FAQ
❓ Frequently Asked Questions
The questions that come up most when readers are shopping this list
What's the actual size limit for Spirit and Frontier personal items?
Both airlines let you bring one free personal item that fits under the seat in front of you. The limit is 18 inches tall, 14 inches wide, and 8 inches deep. Frontier's bag sizer is tighter than Spirit's, so the bag has to slide in unassisted, or you get charged $99. Every bag on this list is built to fit that box.
Is the Vancropak worth $23 more than the WANDF?
If you fly more than a couple of times a year, probably yes. The Vancropak has a USB port (you supply the battery), a removable shoe compartment, a padded sleeve for a 17.3-inch laptop, and water-resistant pockets. The WANDF at $9.99 is essentially a foldable nylon sack. The fabric is thin and I wouldn't trust it with electronics, but for the occasional weekend trip it's fine.
Can I use these as a carry-on?
No, they're personal items and they go under the seat, not in the overhead bin. If you want overhead bin space, you'd need a standard carry-on, and on Spirit or Frontier that means paying the checked bag fee. The trade-off with a personal item is you fly free, you deplane faster, and your stuff is at your feet the whole flight.
Do these work for an apartment move?
The Vancropak and Narwey are decent for a small move. They hold 20 to 40 liters and they fold flat for closet storage when you're done. The WANDF is too flimsy for anything heavier than laundry. A renter-friendly trick: keep one packed with your essentials during the move (documents, toiletries, a change of clothes) so you're not blocked if the rest of your stuff takes a detour.
The bottom line
If you’re flying Spirit or Frontier and you don’t want to pay $99 each way for a checked bag, the Vancropak Personal Item Backpack at $33.24 is the bag I’d pick. It has the only USB port in this group, a real padded sleeve for a 17.3-inch laptop, and a removable shoe compartment that keeps dirty runners away from everything else. The 18 by 14 by 8 dimensions slide under the seat without forcing, and one round trip pays for the bag.
The Narwey at $24.99 makes sense if you want a wet pocket or a flatter fold. The WANDF at $9.99 is the cheapest thing on this list with 18,000+ reviews, and at that price it’s worth keeping one in a drawer as a backup.
