In anyone’s books 2.85kg is good for an 85l holdall with plenty of expedition-biased features. The tough PD620 outer material is reasonably flexible, meaning the bag doesn’t hold its shape well, but it’s tough and should shrug off a lot of bad weather.
Likewise, the zippered opening is long, with a sturdy, lockable, weatherproof zip. However, this easily catches on fabrics packed inside the bag, as there’s no zip guard.
There’s not much in the way of organisation with this bag – just a small pouch inside and a sleeve on the outside. There are daisychain loops on the outside though, which are handy if you need to strap more items to it.
The long, lockable zip is a boon, though a guard behind it would nullify the risk of snagging on the contents
The Duffle's profile is relatively short, with a correspondingly wide wheelbase. There’s lots of ground clearance and the space between the wheels has an aluminium plate for durability.
The lack of much structure means a lightly packed bag will sag a bit when pulling on the lightweight and comfortable strap-adjustable handle, even with the internal compression straps used. There are a couple of grab handles and the Duffle benefits from also having padded and adjustable shoulder straps.
