The Duffelpack from Peak Design expands from 45L to 65L (a little too large for carry-on on most airlines), has backpack straps that hide away, is made of weatherproof material and is a durable and organized companion for LOTS of different kinds of adventures.
Material Choice:Sub-Par Satisfactory Excellent
Excellent dirt resistance, scuff resistance and all around protection for your gear in this thing. Custom hardware. This stuff is very unique. Weatherproof, 100% recycled 600D nylon canvas. 900D Ottoman-weave Poly bottom fabric. Silicone-coated mesh internal pockets.
Build Quality:Sub-Par Satisfactory Excellent
Peak works with excellent factories. The build on this thing is great. They're innovating so much with this thing.
Water Resistance:Sub-Par Satisfactory Excellent
Great protection from weather for your gear. Water sealed zips, totally water resistant fabric.
External Access:Sub-Par Satisfactory Excellent
I was surprised these side pockets are so useful in transit! One on each side, large enough for a water bottle.
Internal Organization:Sub-Par Satisfactory Excellent
Solid zipper pouches up against the inside of the bag on both sides. Travel docs, accessories, etc.
Capacity:Sub-Par Satisfactory Excellent
Expandable from 45-65L. I love how the main compartment opens like an old doctor's medicine case. If you leave lots of room you may be able to sneak this on as a carry on on bigger airlines. For car camping and general adventuring, this has plenty of capacity for multiple family members.
Carry Comfort:Sub-Par Satisfactory Excellent
Excellent grab handles (so cushy and robust). Straps are solid. Wider-necked people may find some rub on their necks if the bag isn't packed out fully.
Doesn't Look Weird:Sub-Par Satisfactory Excellent
It's the bag Elon Musk should be using as the "team bag" for mars missions. Futuristic. Techy.
Extra Score:Sub-Par Satisfactory Excellent
Gotta give it an extra point for being a bag you buy once and use for a LONG time for LOTS of activities. Extremely useful bag.
The handles around the entire bag are easy to grab and leverage when you’re in “streamlined mode.” Straps may be a little tight on the neck if bag isn’t fully packed.
Can maybe get away with it as a carry-on if you don’t fill it up. Soft panels means you can stuff it into lots of different spaces. Plenty of room in here for both my wife and I whenever we travel. Could probably fit our 2yo’s stuff in there as well.
The zippers, handles, clips and straps all instill a bit of confidence in this bag as you’re strapping, pulling, hauling, etc.
Some people are going to wish there was more padding. Some people may notice a little rub on the neck with the straps. But these straps make this one of the best travel duffels around.
