The ULA Circuit is likely one of the hottest thru-hiking and backpacking packs out there at the moment. It’s a traditional ultralight type pack with an open entrance mesh pocket, a roll-top closure, a spacer mesh again panel behind the shoulder straps, and enormous facet water bottle pockets. My favourite function of the pack is its broad hip belt, normal on ULA’s in a single day packs, which gives wonderful load-to-hip switch and a few vertical adjustability so you possibly can dial in an excellent match. For a whole breakdown of the options of the ULA Circuit, see the ULA 24 Extremely Circuit Evaluation 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 under for winter use is the material the packs are made with.

ULA contacted me to ask whether or not I’d overview 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 loads of various things to totally different individuals by way of climate situations and tools wants, so let’s get particular.
Winter Backpacking and Packing Necessities
Three-season backpacking or thru-hiking is often achieved in snug climate, with good beta in relation to path situations and water sources. However that’s not the case with winter backpacking the place there’s a lot much less certainty about what you’ll encounter. Temperatures are often under freezing, winter days have a lot much less daylight, most water sources are frozen and it’s troublesome to foretell what backcountry path situations might be like by way of snow depth or ice.
Climate situations may also differ broadly, particularly at elevation, the place excessive wind speeds and wind chill enhance the hazard of frostbite or hypothermia until you carry further insulation and face safety. You must count on to make frequent layer adjustments to keep away from overheating and sweating, but it surely’s essential to reduce stopping to keep away from changing 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 mountaineering. Since you possibly can’t eat all of the energy you’ll want in the course of the day at breakfast or lunch, it’s essential to snack very regularly and to have your meals simply accessible so you possibly can eat on the transfer.
From a packing perspective, which means that it’s a must to carry much more weight by way of meals, water, and gas. You’ll need to carry 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 possibly can count on to hold a number of very cumbersome objects that may’t match inside your pack like snowshoes, a foam sleeping pad to take a seat on when melting snow and cooking, traction aids like microspikes, and in lots of instances extra gear together with crampons, an ice axe, avalanche shovel, climbing gear, or ski tools. This extra tools 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 high lid pocket is just about a must have for winter use since it will possibly maintain further gloves, hats, goggles, and face safety that you really want prepared entry to in the course of the day with out having to open the principle compartment of your backpack to entry them.
- A floating high lid is an actual asset as a result of it may be used to carry gear piled on high of the principle 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 gadgets with sharp factors like a foam sleeping pad, a shovel, snowshoes, or crampons. You’ll be able to’t put this stuff contained in the backpack as a result of they’ll take up an excessive amount of area, they will’t match, or they’ll be lined 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 gadgets to the surface 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 retaining 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 principle compartment with out having to open the highest. That is particularly useful on a high-volume backpack over 70L in quantity.
- Ice axe loops and shaft holders to safe axes to the surface of the pack.
- A hipbelt with a giant heart buckle that doesn’t fill with snow and can be utilized whereas carrying 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 record above, the Circuit is awkward to make use of, significantly 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 high pockets than can deployed over their rolltop pack luggage, so you’ve got the most effective of each worlds relying on the season. (See Additionally: 10 Finest Winter Backpacking Packs)
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 talk about under.
Mesh again panel and hipbelt padding
The Circuit’s again panel and the within of the hipbelt are lined with a porous mesh that picks up snow whenever you put the pack down. This melts in your clothes whenever you put the pack on and makes it moist, which could be very undesirable in winter.
Hipbelt
While you put the Circuit hipbelt on it’s good to tighten it by pulling on 4 webbing straps that stress the belt utilizing ladder locks. This will solely be achieved by eradicating your gloves in winter since you want a fantastic diploma of dexterity to seize the ends of the webbing. An easier hipbelt with a a lot beefier heart buckle that doesn’t clog with snow is extra fascinating.
No exterior closed pockets
All the storage on the Circuit is in the principle 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’ll be able to’t put the within the entrance mesh pocket as a result of they’ll get moist there and develop into ineffective. When you can put snacks into the hip belt pockets, they’re not giant sufficient to carry this further accent clothes. The one various is so as to add a big third social gathering chest pack hooked up to the entrance shoulder straps.
Snowshoes
Essentially the most environment friendly option 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 facet 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 facet of the pack with one finish in a facet pocket. There’s additionally no method so as to add your personal facet straps as a result of there are not any gear loops sewn into the vertical rear seams alongside the facet of the again panel.
Evaluation
For those who’re searching for a backpack that may span four-season use and your winter situations dovetail with those described above, I wouldn’t suggest getting the ULA Circuit. It’s simply not arrange for versatile winter backcountry use. It’s fantastic when you solely want to hold microspikes or crampons over a brief snow-covered part of path, but it surely’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 value making an attempt to reengineer the Circuit to be four-season prepared. There are simply too many function and structural adjustments required that it’d in all probability be extra expeditious to design a wholly new pack on the pre-existing Circuit or the bigger ULA Catalyst body.
I hope this evaluation was at the very least helpful to provide you a style of what to search for in a winter-capable backpacking pack and tips to packs, together with light-weight backpacks, that may span four-season use.
