The external frame pack is back! The Ti-Arc is a first generation backpack from the company that brings us all things titanium. As an initial foray into pack design, the Ti-Arc is a solid first step, merging the best aspects of external and internal frames.
The design is innovative. The comfort is phenomenal. Vargo still has a few kinks to straighten out in the design. However, the Ti-Arc has decisively brought the external frame pack back out of obscurity. This is the pack I want with me on the trail!
- One of the lightest external frame Ppacks on the market
- Quality construction, durable materials
- Extremely comfortable

- Belt designed for wider-girthed hikers
- Small front-loading opening
Preface: I spend a good portion of this review suggesting areas of improvement. But if I were setting out on the Appalachian Trail today, this is the pack I would be carrying. Yes, it weighs a pound more than my UL internal frame pack, but that is a reasonable tradeoff for the comfort and stability it provides.
The greatest “con” to this pack is I'm not sure I can go back to using another one, knowing how good this one feels.
I spent six days hiking 85 miles of the River-to-River Trail in Shawnee National Forest. The Shawnee hills provide continuous elevation change similar to hikes in the Appalachian Mountains (although elevation is, overall, lower). I hiked roughly15-17 miles, most days.
The trail presented scores of stream crossings and climbs over fallen trees. Often times a good “jump” was needed to get across obstacles. Footing ranged from gravel roads to rocky ascents to muddy horse tracks. I set out with a pack weight of 25lbs 3oz, including all consumables.
I am a 46yo male, standing 6'2” with a 34” waist. Arthritis in both my knees has forced me towards a “Light” (but not a true “Ultra Light”) approach. I have found a baseweight of 13-15lbs keeps me comfortable both on the trail and in the campsite.
An UltraLight Pack?
The first argument any ultralightest is going to make is that 2lbs 13oz is on the heavy side for a pack claiming to be “ultralight.” Add to this the fact that Vargo gets to that weight by reducing overall capacity to 36 liters. The Ti-Arc holds to the “old school” mindset that people still want to strap their rolled up sleeping bag to the bottom of the pack.
For my own usage, I had to grab a large compression sack, thread the straps through the frame, and carry my tarp and hammock here. The compression sack weighs in at 6.2oz. So in actuality, my pack weighed 3lbs 3.2oz (versus my 60 liter internal frame pack at 1lb 13oz.)
- Suggestion #1: Forget about marketing this as UL. Increase the body of the pack to the full length of the frame to increase volume (also makes side pockets deeper). If that is too much of a design change, at least add integrated compression straps to the bottom of the pack so that any stuff sack can be strapped here.
Construction & Durability
A second, positive reason this isn't an UL pack is that the materials are too durable. Ultralightests know they sacrifice longevity in the name of saving weight. The Ti-Arc relies on 70 denier ripstop nylon for the bag. This is both light and durable. I never worried about the need to baby this pack to keep from damaging it.
Comfort, Fit & Ride
This is where the Ti-Arc blows away anything else I have ever used. I will gladly sacrifice a full pound from my internal frame pack for the comfort of the Ti-Arc. UL hiking is about feeling comfortable and fresh at the end of the day. The Ti-Arc provided this. There was never a time when I groaned as I put it on. My shoulders and back were never stiff or sore during my six days on the trail.
The mesh backing on the frame allowed air to circulate across my back, keeping me from becoming hot and sweaty.
The adjustable lumbar support was worth every ounce of weight it adds to the pack. This feature alone was the best selling point of the Ti-Arc!
- The titanium frame supported the entire pack to keep it from sagging on my shoulders. This allowed the pack to move with me, rather than push or pull me on hills.
External frame packs are known for being top heavy. However, the Ti-Arc was simply perfect. I did not need to lean back on descents or lean forward on ascents in order to maintain my center of gravity. Vargo accomplishes this with a unique approach to attaching the bag to the frame.
One “con” on fit is that I nearly bottomed-out the belt with my 34” waist. Vargo's website says this will fit someone down to a 30” waist, but I am a bit skeptical of that claim. Were I to be dropping pounds on the AT, I would be concerned about becoming too skinny for this belt.
- Suggestion 2: Since the belt is easily removable, offer an optional, smaller belt.
I've already mention that 36 liters is a bit sparse for the long trail. My first concern was could I really pack a week's worth of gear into this unit? I decided to over-test it, by not only packing what I planned to carry during my 6-day trip, but by adding everything I would take on a six-month trek on the Appalachian Trail.
Success! Additionally, I discovered that during my 6-day trek I became more efficient at packing and repacking this unit. By the third day of the trip, I was questioning if I even need the compression sack attached to the bottom—but that was with my food bag half empty.
I listed as a “con” that the front-loading, zippered opening is a bit small. After a couple of days I was no longer noticing this. It may be that I just prefer a top loading pack, where it is easier to stuff things in.
- Suggestion 3: Make the pack top loading, with a roll top and drawn string (Maybe that's an entirely different model in the Vargo line of packs!).
Quirks in the Top Design
The entire top of the pack strikes me as inefficient. As shown previously, the bag slides onto the frame, which is quite clever. But the prongs extend so far above the bag they create two problems.
At one point I snagged on a low hanging vine. This jerked me to an abrupt halt and required a bit of gymnastics to get myself free.
I was unwilling to carry a rain cover, as I believe the prongs would tear a hole in it.
Instead of carrying a rain cover, I simply used a trash compactor bag inside the pack to keep gear dry, but that highlights more of the problems with the top...
Notice the recessed top of the bag. This frustrated me as wasted potential storage space.
But in rain, this recessed area simply became a water catch. This insured water would slowly seep into the pack instead of shedding it. A hiking partner sarcastically told me to put a pan inside the top of the pack, and I would have a new style of water filter.
I tried to find some use for this top area. However, tie-off points are lacking. One attempt was to place my camp shoes on top and stretch the bungee net over them. However, I found that I maxed out the cord in this attempt. So much so, I was unwilling to put my rain coat under it for fear of snapping it.
- Suggestion 4: Shorten the prongs as much as functionally possible to reduce snagging.
- Suggestion 5: Include a grommetted rain cover that will slide over the prongs
- Suggestion 6: Either get rid of the recessed area and add volume to internal storage, OR...
- Suggestion 7: Add a second bungee net to the top of the pack to shove in rain gear, and etc, OR...
- Suggestion 8: Add a few grosgrain loops to the top of the pack, along the “arc” suspension bar to tie items down
Titanium is not cheap. At $300, the Ti-Arc is not the most expensive pack on the market, but it is the most expensive external frame pack I know of, with half the carrying capacity of many packs. My thought is many shoppers will compare a ratio of “cost of pack TO weight saved TO carrying capacity” and look past this pack. I feel that's a shame! Vargo is going to have to aggressively market this pack to overcome that ratio, and that marketing needs to focus on the comfort of the Ti-Arc.
- Suggestion 9: Sponsor a 46yo, fairly handsome guy with arthritis in his knees to hike long trails and be the spokesman for the comfort of the Ti-Arc. He will gladly quit his day job to do this.
While not a true ultralight pack, the Ti-Arc definitely falls into the category of “light.” It is also the most comfortable pack I have ever used. I expect future versions of the Ti-Arc to continue to improve on the initial design. In its current version, the Ti-Arc is well worth taking on the trail.
It is simply the best pack I have ever used!
Where to Buy
Finally, the next step in external frame backpack evolution—an ultralight pack with traditional external frame support. The Vargo Ti-Arc and Ti-Arc CF ultralight external frame backpacks combine the best features of internal and external frames for an unparalleled support-to-weight ratio of any pack.
At its core is a formfitting titanium alloy frame with an ergonomically designed lumber plate to provide excellent load transfer to the hips and sag-free comfort. A streamlined 36 L “Arc” bag in either ripstop nylon or cuben fiber (CF models) holds plenty of gear while leaving room for attaching bulky items to the frame.
