The Travel Duffel from Peak Design is a simple travel companion with some very useful features like weatherproof materials and killer external access pockets.
Material Choice:Sub-Par Satisfactory Excellent
Excellent dirt resistance, scuff resistance, water resistance. Custom hardware. Weatherproof, 100% recycled 400D nylon canvas. 900D bottom fabric. Silicone-coated mesh internal pockets.
Build Quality:Sub-Par Satisfactory Excellent
Solid all around. The design itself thoughtfully deals with common points of failure.
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
Two layers of external pockets on both sides of the bag. Each large enough for a water bottle. Some have simple internal org panels.
Internal Organization:Sub-Par Satisfactory Excellent
Zipped pouches inside the bag, one on either side.
Capacity:Sub-Par Satisfactory Excellent
No gimmicks or extra material on this thing, so it's just pure capacity in the main compartment. More capacity than some +40L bags.
Carry Comfort:Sub-Par Satisfactory Excellent
Shoulder strap is fine. Top and bottom handles are great. Main handles can get irritating. (More in video.) Wish there was a way to carry the bag from the pocket-side of the bag
Doesn't Look Weird:Sub-Par Satisfactory Excellent
Sleek, clean, minimal.
Shoulder strap is totally satisfactory, no problems there. But the handles can get a little irritating. You’ll get used to your own way of organizing them before you pickup the bag.
Other Bags to Check Out:
The Western Flyer from Tom Bihn is a small duffel/backpack conversion travel bag designed for quick trips or minimal travelers.
The Core Pack from Topo is a classic daily carry bag with solid organization and materials at an extremely affordable price.
A very functional eco-friendly bag, the Wayks One expands and compresses into multiple different functions, making it a great bag for daily and travel use.
An extremely solid everyday backpack suited for carrying lots of gear or compressing down to a minimal daily carry haul. One of my favorite all-around bags.
The Outbreaker backpack from Tortuga is a solid 1-bag travel pick. I personally prefer the less bulky (and more spacious) experience of traveling with the Tortuga Setout, so be sure to check out that bag too. This Outbreaker, however, has quite a bit more padding and protection around the entire bag, so if you know you'll have delicate stuff inside you may prefer this one.
