Me fui a Europa por casi un mes con esta mochila solamente y fue perfecta. No pesa nada, se hace grande o pequeña y es súper práctica. Además de que las medidas son perfectas para no tener problemas de equipaje con las aerolíneas. La súper recomiendo.

I was able to pack enough in this for a month-long trip to Europe last year. I may never check luggage again.

Bought this for my gym stuff and accessories needed something big enough but not to big this works perfectly , love the size and different pockets for storage . Was never a big fan of back packs as they never stay on my shoulder using just one strap but this one is very comfortable and stays put . Great pack for. Y needs . And at a good price .

I bought 2 SEMSTY Hiking Backpacks for my 3 month Mexican trip. I have never regret doing that.1. The backpacks capacity can be adjusted to fit everything you need. I am a remote worker and I travelled with a 24" monitor and a small desktop NUC PC which I needed for my job. There was not problem to put the monitor in the backpack.2. The backpacks qualify as carry on items at all airlines.3. The backpack can be slimmed down to look a laptop backpack.4. It is convenient to carry for a long time even when it is heavy even for a woman.5. None of the backpacks broke after 3 months of daily use.6. And it is inexpensive.

I purchased 2 of these as a carry on bag to eliminate needing to check a bag. I absolutely love them! The backpack has tons of room and is tough. I highly recommend.

This bag overall is really good, isn't heavy and has great storage. It's super comfortable to wear especially with the chest straps and belly straps, perfect for hiking if that's what you're using it for. Unsure if it's waterproof, I use it to carry mags and my AKP. Fits nicely, overall 5/5

I recently took the SEMSTY Hiking Backpack (expandable to 40L or 50L) on a 5-day trip, and it impressed me with its capacity and versatility. Here's how it performed:Carry-On Champion:The backpack's biggest advantage for me was its ability to fit as a carry-on for my flight. Even when fully loaded for a 5-day trip, it met airline size restrictions. This saved me money on checked bag fees and the hassle of waiting at baggage claim.Packing Powerhouse:Don't underestimate the expandable design! Despite being a carry-on size, I managed to pack everything I needed for my trip, including:Snorkel gear (mask, fins, etc.)TripodClothesTowelCosmeticsThe multiple compartments helped me stay organized, and the expandable bottom compartment provided extra space when needed.Other Features:Comfort: The backpack has padded shoulder straps and a breathable back panel, which helped keep me comfortable during long walks and commutes.Durability: The material feels sturdy, and the zippers functioned smoothly throughout my trip.

I recently purchased this pack for my 10 year old son for a camping trip, and overall, I'm pretty satisfied with it. The backpack is lightweight and has a good amount of storage space, which is great for multi-day camping trips. The adjustable straps and waist belt provided decent comfort, but the waist belt has no padding, so I feel like it would be very uncomfortable on a long hiking trip. The material and construction seem durable, but the zippers can be a bit finicky at times. Overall, I think this is a good backpack for the price, but it may not be the most comfortable option for long hikes. The expandable storage is actually pretty significant, but stretches out the carrying straps on the back making it harder to put things into them. I really wish there were more attachment points for putting gear on the outside of the pack. i.e. tent/sleeping pad/etc. OR at least make the bottom straps clippable/detachable so you can wrap gear into them. Currently, you have to hope you can stuff whatever you want to go in them without pulling the straps out. I’d pay a little extra just for clips on there.If your only intention is using this for a backpack or carry-on/etc. I think you’ll be very happy. I think it needs a few minor modifications to get a full 5-stars for an inexpensive camping/hiking bag

This is a great product at a competitive price. It is the right size at 40 liters to take on s plane as carry on luggage. Then it can be expanded to 50 liters with its zip around compartment. It has a chest strap and a waist strap making it ideal for walking on rough ground or hill climbing. It is lightweight and rugged at the same time. It has six clinch straps making a nice solid pack regardless of how full it is. Nicely padded with mesh material, it it good for the long day hike.I should have ordered this earlier as it was scheduled to arrive just in time for my planned trip. Then it arrived 15 hours later than promised so I had to delay my ground transport and then pack in a rush to make my plane. Mostly my fault but still a minor inconvenience.I am using the backpack in Germany and Ireland for this trip and it is ideal in every way.
