I just took this bag to Mozambique as I'm a disaster response volunteer and we responded to the devastation caused by Cyclone Idai. This pack cover was used (fully expanded) to transport around 35kg of rations and water purification kit for a 4 week deployment. It was treated extremely harshly - thrown around on rough concrete floors, survived multiple flights (including multiple helicopter flights into remote areas), dragged over rough stony ground again and again, covered in mud and dirt, transported on trailers with rough splintered wood and sharp metal cross bars, crushed under aid supplies, sat on for bumpy tractor/4x4 rides and otherwise kicked, thrown pulled and yanked across various areas of the country. It's currently absolutely covered in dirt but otherwise in perfect condition. There aren't even any abrasion marks on the material, let alone any cuts or punctures. It's remarkable. The carrying handles proved remarkably resilient and the tough but lightweight material (guessing 500D or 600D nylon/cordura type material) has handled everything without a single issue. This is a cheap pack so it was abused by various members of the team who had much more important things to worry about that taking care of a bag, and the pack cover took everything in it's stride. My own backpack used in the same environment has several cuts and punctures to the outer material and that received 1/10th the abuse. This is an extremely solid bit of kit and something I'd definitely trust to use again.

My son is off on a tour of Asia and bought this as an over bag to protect his rucksack straps whilst in flight. It will serve as a second bag on way back.

I'm really impressed with the design of the flight cover. It has a shoulder strap that unclips and folds away into a pocket. The expanding section is really well designed too. It's very spacious with smaller bags and folds away into its own pocket. The fabric feels very tough and I'm looking forward to really putting it to the test on a trip to Nepal.

This bag is perfect for car booster seats (2) when travelling by plane and fab that when not in use it folds into itself to make a small pouch - brilliant idea!

Only used on 2 flights , but seems very well made, no complaints so far

I used this for my 65ltr backpack when flying to USA to hike a section of the appalachian trail, the pack fit nicely inside with room to spare, it also weighs very little (about a pound) so I didn't notice the extra weight I was carrying for two weeks. It feels very good quality and should be good for several years!

V good quality-we got 2 for my nieces who were going travelling. We were worried that other products would too easily but the quality of this is excellent. The expandable section is a great idea so that the product stayed snug around the pack.

Like the expanding opening at the bottom allowing backpack with hip strap to be accomodated

I know this is intended for covering back packs etc, but we have brought to put our child car seat in when we go on a flight. Our seat fits perfectly in the bag so now the stress of it getting filthy is gone

My Backpack, a Quechua, fits inside well with a little room to spare. It will keep it safe and undamaged when in airports again.

Perfect for transport and protection for plane. Used for 80l.

Protect your backpack whilst travelling. Use as independent sack type luggage, of needed.
