Why We Like The Scepter 50L Backpack

From scaling icefalls to braving thin air for the ultimate summit grab, the Scepter 50L adapts to the mission. For increased mobility and functionality as we climb, we remove the hip belt padding for a more low-profile fit and to expose two ice clipper slots. When we're spending days postholing through deep powder, we cinch all 5 compression straps tight to pull our load in close and let the dynamic frame sheet and hip belt do the rest. However we send it, the rugged materials don't flinch at the harsh conditions we slog into.

I turned it into a multi sport bag

I really needed a 50L pack for larger trips. This bag initially looked like it was perfect but once I received the bag, the design was just too weird. I made a bunch of modifications and I think I love it now? I can put skis on the sides now, I can access the side zip access now, There are a bunch of usable pockets with some added zippers. A shovel actually fits inside the outer black pocket. this season will tell but it is much more functional than it was originally before. Mystery Ranch people, I would love to talk more about the modifications I made if you are interested!

A lot of good, some bad.

I have used this pack for five days on Mt Shasta and Mt Lassen. I like some the design features, like the shovel pocket and compression straps. I wish they made a 65 L for winter and spring ski mountaineering trips. It is a little small. I have the smaller version and love that pack. I felt like the hip belt was under sized for the 50L size. Plus, the stitching has begun to rip at the hip belt. Last I wish there was a brain pocket for easier access to headlamps, snacks or sunscreen. The small pocket is difficult to access when loaded. It's a good pack, but out if the 7 MR packs I own I'd put is at the bottom.

Fantastic alpine climbing pack

I've been using this pack for the last winter ice climbing season and it's fantastic. Carries and spreads weight very evenly around the hips and shoulders, doesn't cut in, climbs very well on mulitpitch. I'm a small-framed woman (5'2") and have the S/M size for this pack and it fits perfectly. Love the side-accessible zipper for when I need to grab something from the bottom of my pack and the pockets at the top for storing the essentials.

Great backpack! Some critical issues

Love this back in terms of design and function. Great for ice climbing and skiing. The only downside is the buckles don't work when it's freezing out, and they get only the slightest amount of snow/ice in them. In Montana, that happens more often than not, and I've had the buckles freeze and not snap during several mission-critical moments that have caused some significant issues

Nailed it

This is a perfect ice climbing pack. The product video makes it seem like this pack is oversize for a day of ice, but I usually carry a full 35-40 liters of kit and would rather compress a bigger pack than stuff a smaller one, so I think it is just right. The compression straps shrink it down and I love having extra room for my insulation, schnapps, harness… etc.

Scepter 50 Carries the Load!

I bought the Scepter 50 recently to replace a very well worn Bomb Pack. Although I don't really do any significant climbing any more, I like the larger single compartment design for carrying significant amounts of camera gear on longer day hikes. I've found that the tool carry feature on the back of the pack can be easily adapted to carry a large tripod very securely. What I really like: It carries a load very comfortably. I've probably only had 25-30 lbs in it so far, but it all goes to the hip belt and rides very comfortably. The material looks like it will hold up to a lot of abuse, which is inevitable! What could stand improvement: The small top pocket is going to take some getting used to. I'm definitely used to the roomy top pocket in the old Bomb. Guess I'll use some smaller bags in the main body to group stuff together. The buckles seem to take more effort to buckle than the old Fastex buckles; I seem to miss a lot when I go to fasten them. Probably will get better with more practice. Overall, a very high quality product that will probably outlast me. I shopped around for other brands, but they seemed to be more interested in looking pretty and having little "bells and whistles" features than carrying the load in the long run. I really appreciate that Mystery Ranch has focused on the mission of their product, and not just making them marketable to the masses.

Sweet top loader wish it had a pocket in the Brain

It does all your typical MR pack would do, but I wish it had a brain in the top flap to store stuff... shovel and probe pocket is adequate but watch out for oversized probes and shovel handles & blades that may not fit.

Suggestions for refinement

Bought this pack in size L/XL as a winter-oriented upgrade for my old Pitch 40. Pros: -Excellent materials -Great colors -Good choice of buckles -Ample volume Cons: -Blowing snow and spindrift enters pack via hydration hose openings -Pack body length insufficient to allow load lifters to function optimally for taller users; load lifters pull back and down on the shoulder yoke rather than back and up -Single stay design transfers load less effectively than older two stay designs -Single stay design contributes to load lifter dysfunction; rather than translating load lifter forces directly down to the hip harness via dual stays, the pack body sides collapse before engaging the single center stay -Unused potential space between lid fabric layers Suggestions: -Equip small hook-and-loop closure strips to close hydration hose openings -Lengthen pack body to keep load lifters above shoulder yoke for taller users -Revert to two stay design for more effective load lifter function and overall improved load carriage -Permit zipper access to potential space between lid fabric layers.

Simple Light Weight Pack

I use this pack mostly for ski touring. It fits all my gear well and has the separate pocket for my backcountry tools. This pocket is a little shallow for long shovel handles, but it still works well. The suspension system has a lot of room for adjustment. I had purchased several packs, however my longer torso (~22") didn't fit other well. This pack has plenty of adjustment. It is also very simple but large enough for all my layers, helmet, skins, food and water. An entry system that accessed the bottom of the bag (maybe a single vertical zip near the bottom on one side) would be helpful, but is large enough usually to reach down to the bottom without having to take everything out.

Awesome Ice and Mountain Pack

Super rad pack! Haven't heard much of mystery ranch but decided to buy this bag after looking into the company's reputation. Turned out to be the best climbing pack I've ever owned! Super comfy and can hold a ton of weight. Also super durable for its weight, I've beat this bag up and have yet to damage the fabric. I ice climb and mountaineer with it and their ice axe/tool attachment system works perfect, no complaints. All said super impressed with the bag, if you're looking for a durable alpine pack I highly recommend the Scepter.
