Our Verdict

For ultrarunners who want to go further, the next step is fastpacking: bringing a super light camp kit to be able to travel overnight and maybe get some shuteye along the journey. The UltrAspire Bryce XT can carry all of the gear needed for a multi-day run or a multi-sport day. Heavier ripstop material adds durability, but also weight. While we didn't love this pack for running exclusively, its utility shone through on bike-to-run missions. Plenty of storage space is oddly divided up into a complicated pocket layout. But for the right person and applications, this can be a sweet little pack.

Our Analysis and Test Results

For the runner who says yes to any type of endurance outing, fastpacking, run to pack raft, bike to run, or run to climb, this pack is going to be of interest. For the runner looking for a simple hydration vest that will assist in adding some mileage to your long run, this vest might seem a little loco. But we like loco. There are just some quirks we noticed that are worth noting.

Comfort


The length and shape of the Bryce XT will not be compatible for everyone, as the pack is narrow between the shoulder blades but widens as it extends down the pack. We found that this impacted how it carries gear and weight, putting more stress on the lower back.

Elastic fit straps on the sternum and static webbing straps across the sides keep what can be a heavy load secure. This is one of the few packs we tested that doesn't permit vertical movement of the sternum straps for different preferences. These slight points of friction contributed to the general comfort of the vest.

Features


Not many running packs have helmet carry options in addition to ice axe carry systems. The feature set of this pack was what caught our attention. An insulated hydration sleeve, ice axe carry, and full water resistance scream winter adventures, and the extensive front storage options enhance fast movement over rugged trails. This pack was built for the Maroon Bells traverse in Aspen, light enough for fast travel, durable for the couple 5.9 climbing moves and forced chimney shimmy, ready for that afternoon storm, carries all of the gear, and has a helmet carry for the smooth trail run back to your bike.

A handy trekking pole fastener is tucked inside the external storage harness, which itself doubles as the helmet carry.

Hydration System


UltrAspire doesn't include a hydration system with this pack, but it is equipped with plenty of chest pockets and a bladder sleeve. We preferred to use the Bryce XT with a 2-liter bladder, and it even has a magnetic circle for assisting with hose management.

The pocket layout didn't make much sense for using soft flasks, though we tried our best to get a feel for how it would work. The most sensible solution was to place the soft flasks in the large zippered pockets on the chest.

Volume to Weight Ratio


This vest was far and away the heaviest vest we tested, weighing right below 20 ounces without any hydration system. The Bryce XT 15 goes against the trend and, even as a larger pack, still scored poorly for this criterion.

Pockets


One large rear pocket accessed with a zipper opens up to roughly 10 liters of storage with a smaller zippered organization pocket inside. On the outside of this pocket is the large rear external storage that works for carrying ice tools, poles, or a helmet.

Of the six front pockets, three are zippered, and two are magnetic, leaving one pull-cord cinch pocket. We can't get to the bottom of this design, and in this case, these features do not add function; they make it challenging to use the pack with soft flasks and certainly are not intuitive in terms of what should go where.

Value


This pack doesn't scream value to us, as it has a higher price point, doesn't come through strongly for comfort, and scores alongside cheaper options. There is a value argument to be made for durability, as this pack could last decades. But for such a feature-rich pack, it's a bummer to miss the mark on comfort and the utility of simple pockets.

Conclusion


For the right person seeking a four-season pack that won't break down under the toughest conditions, the UltrAspire Bryce XT pack will suit your needs. For the average runner and even adventurous runner, we think there are better options available.
