Shop Princess Kate's exact backpack that fits under airline seats and is 'perfect for hikers' 'The material is tough as old boots and it's a great colour!' We're so used to seeing Princess Kate looking glamorous in her designer coats and dresses that when pictures dropped of her completing a wet-weather Three Peaks charity hike over the weekend, we immediately wanted to know all the details. What did she wear for the occasion? Does she have a favourite waterproof? We haven't had to wait long to find out, because eagle-eyed royal fans have started sharing the exact jackets, jumpers and backpacks Kate wore for the hike. In one of the particularly soggy-looking snaps, the Princess of Wales is seen wearing a sturdy backpack that looks built to withstand all weather conditions. Now, we can confirm the exact rucksack is Fjällräven's Lapland Hike 15. Retailing at £195, it's not a cheap buy, but with glowing reviews, it's definitely one hikers and travellers will use time and time again. Described by the Swedish brand as a versatile daypack that offers maximum freedom of movement for active hunting and trekking, it's easy to see why it got the royal nod from Kate.

It's also the perfect size for popping under an airline seat – no baggage fees incurred. One happy customer who bought the Lapland Hike 15 bag pens: "I bought one this year for day walks with the dog. I pack light, know what I need, with something that’s not big enough to tempt me to add more. This pack has the pockets I use (not think I want) and even includes a great rain cover. I love the slim profile, like the design, and the layout has the straps and loops I want. Yes can get lighter, but you won’t get better. Oh yeah, the material is tough as old boots, a great colour." Another adds: "This is the very best small backpack I have ever had. It is so well designed, with lots of compartments for organisation, and is very rugged. There is room for an iPad and a Fjallraven seat pad, plus all you need for a day or two if your luggage goes missing. The ergonomics are great, too, as it fits so well and leaves lots of room for free arm and shoulder movement. The waist belt is great and I really love the way that it tucks completely out of the way when not needed. "This pack fits easily under an aeroplane seat and still leaves room to stretch your feet on either side of it! The rain cover is quick and easy to deploy and allows easy access to the pack while in use. The innovative felt back cushion is comfortable and doesn't seem to get wet even when I am sweating on a hot day. This pack looks great, too!" A third added a slight critique, noting that the waist strap is more suited to those of a taller stature. If the near-£200 price tag is a little hefty for you, we also love Passenger's Vantage 24L BackpackVantage 24L Backpack as an alternative for £79.95. Featuring a drawcord closure, G-hook lid and plenty of pockets for all your essentials. Plus, with secure zips, an internal laptop sleeve, and handy loops for your gear, it’s also ready for any adventure – Three Peaks or otherwise!
