The ULA Circuit is among the hottest thru-hiking and backpacking packs accessible right now. It’s a standard ultralight model pack with an open entrance mesh pocket, a roll-top closure, a spacer mesh again panel behind the shoulder straps, and huge aspect water bottle pockets. My favourite characteristic of the pack is its vast hip belt, customary on ULA’s in a single day packs, which gives wonderful load-to-hip switch and a few vertical adjustability so you’ll be able to dial in an excellent match. For a whole breakdown of the options of the ULA Circuit, see the ULA 24 Extremely Circuit Assessment I wrote early this 12 months for the blow-by-blow. The one distinction between the Extremely Circuit and the Robic Nylon Circuit I consider beneath for winter use is the material the packs are made with.

ULA contacted me to ask whether or not I’d evaluation the suitability of the Circuit for winter backpacking since that’s one thing we’ve been doing at SectionHiker.com and writing about for a very long time. Now, winter backpacking means plenty of various things to totally different individuals by way of climate circumstances and gear wants, so let’s get particular.
Winter Backpacking and Packing Necessities
Three-season backpacking or thru-hiking is often executed in comfy climate, with good beta on the subject of path circumstances and water sources. However that’s not the case with winter backpacking the place there may be a lot much less certainty about what you’ll encounter. Temperatures are often beneath freezing, winter days have a lot much less daylight, most water sources are frozen and it’s troublesome to foretell what backcountry path circumstances will likely be like by way of snow depth or ice.
Climate circumstances also can range broadly, particularly at elevation, the place excessive wind speeds and wind chill enhance the hazard of frostbite or hypothermia except you carry further insulation and face safety. You need to count on to make frequent layer adjustments to keep away from overheating and sweating, however it’s necessary to attenuate stopping to keep away from turning into chilled since you’re not shifting. Winter meals necessities are additionally considerably totally different as a result of winter backpacking makes use of roughly twice the variety of energy as non-winter mountain climbing. Since you’ll be able to’t eat all of the energy you’ll want through the day at breakfast or lunch, it’s necessary to snack very incessantly and to have your meals simply accessible so you’ll be able to eat on the transfer.
From a packing perspective, because of this it’s a must to carry much more weight by way of meals, water, and gasoline. You’ll need to convey extra sleep insulation, dry clothes, and a number of pairs of gloves, and hats as a result of it’s troublesome to dry clothes within the chilly. Lastly, you’ll be able to count on to hold a number of very cumbersome objects that may’t match inside your pack like snowshoes, a foam sleeping pad to sit down on when melting snow and cooking, traction aids like microspikes, and in lots of circumstances extra gear together with crampons, an ice axe, avalanche shovel, climbing gear, or ski gear. This extra gear can necessitate switching to a winter backpack that may carry extra weight, has extra closed storage and entry strategies, and has higher exterior attachment factors for carrying cumbersome gear.
Fascinating Winter Backpack Options
Winter-specific backpacks and three-season backpacks which can be simple to make use of for winter backpacking include options that make it simple to hold and entry winter-specific gear.
For instance:
- A prime lid pocket is nearly essential for winter use since it might maintain further gloves, hats, goggles, and face safety that you really want prepared entry to through the day with out having to open the primary compartment of your backpack to entry them.
- A floating prime lid is an actual asset as a result of it may be used to carry gear piled on prime of the primary pack bag in place like a coil of rope, a sleeping pad, a tent physique, and even snowshoes.
- Quite a few exterior attachment factors like dual-side compression straps with glove-friendly buckles are good for carrying cumbersome gear or objects with sharp factors like a foam sleeping pad, a shovel, snowshoes, or crampons. You possibly can’t put this stuff contained in the backpack as a result of they’ll take up an excessive amount of house, they will’t match, or they’ll be coated in snow and ice (as you turn between them) and also you don’t them making all of your different gear moist.
- Backside sleeping pad straps for lasting a pad or tent physique to the bottom of a pack are helpful.
- Daisy chains are exterior gear loops for clipping objects to the skin of a backpack from further webbing straps and exterior pockets to insulated water bottle sleeves.
- An exterior crampon pocket makes it simple to hold microspikes or crampons so that they’re simply accessible whereas maintaining the sharp factors away out of your physique and different gear in case you fall.
- Facet zippers allow you to entry or stash insulation layers in the primary compartment with out having to open the highest. That is particularly helpful on a high-volume backpack over 70L in quantity.
- Ice axe loops and shaft holders to safe axes to the skin of the pack.
- A hipbelt with an enormous middle buckle that doesn’t fill with snow and can be utilized whereas sporting gloves.
- A snowshedding again panel and hipbelt padding
How Simple is the Circuit to Use for Winter Backpacking?
In case your model of winter backpacking resembles the winter backpacking necessities I listing above, the Circuit is awkward to make use of, notably when in comparison with winter-specific backpacks just like the Osprey Mutant 52 or the Black Diamond Mission 75. Different light-weight backpacks just like the Granite Gear Blaze 60 or the Granite Gear Crown3 60 are additionally considerably simpler to make use of as a result of they’ve twin compression straps on three sides and non-compulsory floating lid prime pockets than can deployed over their rolltop pack baggage, so you will have the perfect of each worlds relying on the season.

That’s to not say that you simply couldn’t hack the Circuit with third-party webbing straps to create higher attachment factors, however the present pack design remains to be restricted in that regard as we focus on beneath.
Mesh again panel and hipbelt padding
The Circuit’s again panel and the within of the hipbelt are coated with a porous mesh that picks up snow if you put the pack down. This melts in your clothes if you put the pack on and makes it moist, which may be very undesirable in winter.
Hipbelt
While you put the Circuit hipbelt on you’ll want to tighten it by pulling on 4 webbing straps that pressure the belt utilizing ladder locks. This may solely be executed by eradicating your gloves in winter since you want a wonderful diploma of dexterity to seize the ends of the webbing. A less complicated hipbelt with a a lot beefier middle buckle that doesn’t clog with snow is extra fascinating.
No exterior closed pockets
The entire storage on the Circuit is in the primary pack bag, so there’s no place to place further gloves, mittens, hats, goggles, or face safety contained in the pack with out stopping, opening the pack bag, and retrieving this stuff. You possibly can’t put the within the entrance mesh pocket as a result of they’ll get moist there and develop into ineffective. Whilst you can put snacks into the hip belt pockets, they’re not giant sufficient to carry this further accent clothes. The one different is so as to add a big third get together chest pack connected to the entrance shoulder straps.
Snowshoes
Essentially the most environment friendly strategy to carry snowshoes is alongside the edges of a backpack, near your hips. That is simple to do with backpacks which have dual-side compression straps with glove-friendly side-release buckles. Sadly, the Circuit solely has one aspect compression strap, that closes with a glove-unfriendly ladder lock and a brief webbing strap that’s solely barely lengthy sufficient to safe a foam pad to the aspect of the pack with one finish in a aspect pocket. There’s additionally no manner so as to add your personal aspect straps as a result of there aren’t any gear loops sewn into the vertical rear seams alongside the aspect of the again panel.
Evaluation
In the event you’re on the lookout for a backpack that may span four-season use and your winter circumstances dovetail with those described above, I wouldn’t advocate getting the ULA Circuit. It’s simply not arrange for versatile winter backcountry use. It’s wonderful when you solely want to hold microspikes or crampons over a brief snow-covered part of path, however it’s not simple to pack when it’s a must to carry quite a lot of snowshoes and mountaineering instruments for any size of time. I additionally don’t suppose it’s actually price making an attempt to reengineer the Circuit to be four-season prepared. There are simply too many characteristic and structural adjustments required that it’d most likely be extra expeditious to design a completely new pack on the pre-existing Circuit or the bigger ULA Catalyst body.
I hope this evaluation was at the very least helpful to present you a style of what to search for in a winter-capable backpacking pack and tips that could packs, together with light-weight backpacks, that may span four-season use.
