Love it! Got everything in & very comfortable to carry

I got the underseat backpack in petrol blue (lovely teal) and it's fantastic! Really comfortable, love the dividers. Fits everything easily for a long weekend. I travel a lot (usually on trains) and I really appreciate the very secure zips. Really pleased.

Exactly what I needed, love all the sections, was perfect on a long haul flight to Mexico! Looking forward to repacking for my return trip home! Would definitely recommend.

Excellent customer service. My backpack arrived within a few days of ordering. Perfect size, and able to fit everything I need. Plenty of zipped pockets, to keep important items safe. Very good quality.

Customer photo review of The Underseat 15L

Åkte till Krakow, 4 nätter. Perfekt att ha det lilla som behövdes med. Hoppas på att kunna spara ihop till en väska till. Oklart vilken storlek. Nu packar jag den för att åka tåg med 3 övernattningar och känner att jag inte är behov av att packa så mycket som jag gjorde förr. Nu är utmaningen mer, hur lite behöver jag med mig? Syrran lär bli överraskad över hur lite jag klarar mig med nu för tiden. Grym väska! //Cina

It seems great, but I haven’t used it yet. It would be better to ask me in a year’s time

The bag is really well designed and I'm enjoying using it every time I travel. I love the flexible compartments and space for passport and wallet. There were no problems on Ryanair!

A very neat bag - could do with an extra strap to pop over a wheel-y suitcase

The perfect under seat back pack, just what I’ve been looking for. Cycling helmet fits in , with tablet and few bits and pieces Not had the chance to use it properly yet. Recommend you run the zips open and close a few times before use.

I ordered this for my trip later this year but am finding it so useful with all of its little hidden pockets etc. So adaptable.

Absolutely love my rucksack! Bit dubious after seeing it so much on social media but 100% amazing!

K L. 5/5 Verified

The Underseat 15L

Great back with plenty of pockets, practical for small flight bag. Really like it but Zips very stiff due to thickness of seams around them. Not used as yet. I thought the top pocket was separate however it has a divider to seperate it from the main part of bag.

I haven't used the 15L underseat bag yet on a flight (coming soon), but have used it for weekend car trips. The material is not as soft as other rucksacks I've used, so you can't 'stuff' as much in as, say, my CabinMax 'travel hack' bag. The dividers and multiple pockets are useful and I think will come into their own on a flight where I need access to different items at different times. It's fairly lightweight and nice to wear, and looks smart. Using it a few times will probably reveal the best way of packing it!

Just what I needed for a trip to Norway and now used for my daily carry

The bag itself is very well made and functional. I knock a star off because the purchase included free add ons but what was not clear was that two of the add ons selected did not work with this bag.

Love it - very well made

Christopher G. 5/5 Verified

The Underseat 15L

Jämfört med 20l och 30l känns denna mer genomarbetad. Där är fler fack att sortera i locket, två sidofack istället för bara ett. Båda har nät som smiter åt en vattenflaska bättre vilket gör att den inte trillar ur. Handtaget är lite längre vilket gör den lättare att bära med en hand. Dragkedjorna är betydligt lättare att öppna och stänga. Samtliga är dessutom vattentäta. Det enda problemet är att den är för liten för en vuxen människa och ser ut som en barnryggsäck när man har den på sig.

Store owner replied: Hej Johan! Tack för en väldigt genomtänkt recension, så roligt att du uppmärksammar alla detaljer 😊 The Underseat är medvetet designad för att vara kompakt och hålla sig inom måtten för “personal item”, alltså väskan som ska få plats under sätet på flyget. Det är därför den upplevs mindre än 20L och 30L. Vill man ha mer volym är Organizer 20L eller 30L bättre val, men just Underseat är framtagen för den som vill resa riktigt lätt. Smaken är olika när det gäller storlek och uttryck, men kul att du uppskattar funktionerna! Med vänlig hälsning, Noelle

Jättefin och lätt ryggsäck. Blir perfekt handbagage på flygresan.

Jenny H. 5/5 Verified

The Underseat 15L

Väldigt genomtänkt väska i ett format som inte behöver debatteras om den är för stor eller inte jämte rullväskan på flyget. Bra med extra tillbehör
