Is anyone familiar with this Samsonite bag?

Happy (US version) Thanksgiving!
Those backpacks are both 7.5 lbs when empty. I think it's going to be a challenge to meet weight requirements unless you are a devotee of packing very light.
What about just using a folding rolling thing? It would fit under the plane seat seat or next to your backpack/suitcase in the overhead bin.
I think the Samsonite exceeds the height dimension limits, also.

Ok have a little inside knowledge on both these brands. They are both good brands. Osprey has their all mighty guarantee. They guarantee their bags for life. They will replace or fix them. Samsonite had approx a 2 year warranty but they are well made bags. I use both.

As pointed out, the bag you linked to is bigger than most airline's carry on limits.

I have been using Samsonite bags for years. My current one has been used for full time travel for four years. I've had to make two repairs. The first was a wheel which was totally my fault and had nothing to do with the bag, the wheels or the pavement. A wheel on Samsonite spinners can be replaced with just a screwdriver.

The second, which was recent, was having the telescoping handle replaced. This too was my fault as I had extra weight on top of the bag, it fell over and the handle got bent when it
fell into a metal post.

Otherwise, I wouldn't think twice about replacing it with another Samsonite.

But Osprey also makes good bags.

I had noticed the dimensions on the bag were a little large, but on my last trip I checked my bag both ways. My current bag is 45 litres, this one is a bit bigger, but not much. I have looked at the trolley wheels you can attach to a bag without wheels, but then thought that if I don’t want to use it, it becomes one more thing I have to carry somehow. I also came across an Eaglecreek bag, gear warrior I think, that looked good until i read a review where a user said that in the rain, if using the handle, the water ran down into the inside of the bag. Major flaw, I would say. I’m really leaning towards a wheeled backpack that is about 45L, but there doesn’t appear to be too many options. I might just have to wait and see if the Osprey bag goes on sale at some point. I think the Samsonite bag is fairly new as I can’t find any YouTube reviews of it, just a few user reviews on their website. It’s fun to look at all these bags, but also frustrating that the ones I’m interested in aren’t available near me.

I have one other thought! I always carry on, so (empty) weight and size are my #1 requirements but re-reading your posts I see you don't mind checking your bag and the issue is flexibility/comfort when you walk, in transit.
I have a 35 l (expands to about 37) backpack ($$ Peak Design) as well as a July international carryon hardshell suitcase. I tend to either have more "rugged" kinds of trips (RS My Way Alps, Greenland, Patagonia coming up) or urban journeys (Berlin 5 nights).
If it's the former I use the backpack. I had the same experience you described, walking 20 minutes from the bus station in Annecy to my hotel in the old town- the backpack grew annoyingly heavy halfway! OTOH, the narrow streets were just packed with people- no cobblestones- but pulling a wheeled bag would have been more cumbersome.
I also tend to have long layovers and the wheeled option makes those easier.
So my semi- solution is...use both, depending on the trips! There's just always going to be a trade off at some point.
(That original $$ you found looks excellent!)

Bon Voyage, you bring up an idea that has crossed my mind. Just buy a wheeled bag and use that for most trips, saving my bag that converts to a backpack for when I think I will need it. The thing is, on all of my trips I have found instances where I wanted either wheels or a backpack. I’m recalling one long walk from the harbour on Hydra to the hotel where my tour mates were struggling with their wheeled bags. Places like Venice come to mind, also, where it is good to have both options. Though, I’m probably overthinking this, as other people seem to manage. Still, I think I enjoy the search for the perfect bag as I enjoy planning a trip😄

The other Samsonite bag that caught my eye is this one, but not too many reviews on it

From what I've seen on various travel forums over the years, it's not a good idea to use a combination wheeled bag & backpack. When used as a backpack, you'll also be carrying the weight of the wheels and other structural items. The form factor is also not especially good for a backpack. Most importantly most bags of that type don't have a hip belt or adjustment for torso length, which allows the wearer to adjust the pack so that most o the weight rests on the hips. I travelled with backpacks for many years and I can tell you from experience, that's important!!!

It's not a solution I'd recommend. Good luck with your decision.

Ken, I hear what are saying, and many years ago I bought my Tom Bihn bag with backpack straps because I thought getting a bag that also had wheels would not be a good idea. But, after using it on several trips, I now wish it had wheels. There are companies that make wheeled backpacks that get very good reviews. Osprey and Eagle Creek both make bags that do have the proper hip belts. My friend has an Osprey wheeled backpacks, and loves it. It’s just a bit too small for me. I’m eying the Opsprey Soujourn, but I won’t buy it without getting the chance to try it on, and I haven’t been able to find one locally. Oddly, one of the complaints about the bag from some people is that they can’t use the backpack without the hip strap. You can take the whole backpack harness off, but not just the hip strap.

Anita,

I used Backpacks from Eagle Creek and Osprey for years, but decided this year to try a 4-wheel spinner (check-in size) from TravelPro. I've only taken it on one trip so far, and overall I was quite pleased with the change. I used a small Duffel from Red Oxx for my carry-on as it's a convenient way to carry my camera gear as well as the other items I need during transit. However I will make an effort to pack lighter with both bags on the next trip.

For shorter domestic trips, I use either a Tom Bihn Tri-Star (air travel) or a Red Oxx Air Boss (road travel). The Tri-Star has backpack straps but I rarely use them.
