The Mountain Hardwear Scrambler 35 offers lightweight materials and a suspension that moves with you, but lacks the durability and water-resistance of previous versions of the pack. The fabric is abrasion resistant but succumbs easily to punctures. The minimal frame scrambles better than most packs we've tested, and the gear loops are handy for skiing or climbing. While the fabric doesn't soak up water, it isn't seam-sealed, so you'll need a rain cover to keep gear dry. If you're looking for a very minimalist and light pack with some climbing-specific features, it fits the bill, as long as you can live with a few drawbacks.
The only changes to the Scrambler 35 since our test cycle are some new color options. One of the current choices is shown above.
Our Analysis and Test Results
The Mountain Hardwear Scrambler 35 is an impressively light and functional mountain-oriented pack. It nicely mixes climbing-specific features with features like side pockets that add some versatility. While it doesn't live up to expectations in terms of durability or water-resistance, like previous versions of this pack, it does a decent job for a variety of activities.
Without being so minimalist as to exclude handy features, the Mountain Hardwear Scrambler 35 is a decent pack for mixed-technique mountain adventures. Its minimalist suspension is effective, but the fabric is weaker than it looks, and some features aren't as effective as they could be.
We evaluate packs for comfort based on how well they carry a load and whether they allow complete freedom of movement. The Mountain Hardwear Scrambler 35 strikes a nice balance between minimizing weight and being able to carry heavy loads.
With only a thin webbing hip belt and a stiff foam back panel, don't expect to transfer much load to your hips. If your torso fits the pack just right (it isn't adjustable, but comes in 2 sizes), you will be able to get a decent bit of the load off your shoulders, but the lack of load lifters or hip belt padding make it less comfortable than packs that have those features. The shoulder straps can carry a small load comfortably, and don't pinch like some other models.
During our calisthenics testing, we found that the Scrambler didn't hold weight near our backs well, namely due to the lack of lower compression straps. Running or jumping caused weight to shift around, although we didn't notice any issues while climbing. The flexible frame moves with your body, making this pack nice for stretchy activities like scrambling. However, the wide shoulder straps slightly restrict upward reaching, something we didn't have problems with while wearing packs with thinner shoulder straps.
The back panel has some contouring, but isn't nearly as ventilated as suspended mesh back panels, or even grooved back panels.
Weight to Volume Ratio
The Scrambler is impressively light for its capacity, with the lowest weight to volume ratio of any large pack in this review: 0.86 oz/L. Packs with similar volume tend to have weight to volume ratios upwards of 1 oz/L, so this is pretty impressive. We appreciated being able to move fast with this pack while lightly loaded down, but also have the capacity to load up a bunch of gear for climbing or canyoneering.
The material used in the Scrambler is very thin, and it minimizes weight by excluding features like a padded hip belt, front pockets, or many zippered pockets. This pack is meant for those who prioritize simplicity and lightweight. You'll need to pack deliberately to make this pack effective.
This pack is neatly designed with abrasive activities in mind, using the same fabric in both the pack body and the side pockets. Unlike other ultralight packs, the Scrambler uses somewhat durable fabrics across much of the pack, and minimizes straps and attachments where they can often abrade and break.
The Scrambler 35 can do a lot, despite its minimal construction. With a removable top lid, you can strip it down for short or light outings. The two daisy chains make it easy to add elastic or cord to attach crampons. Ice axe loops and lower gear loops make it easy to carry ice tools, part of a climbing rack, or even skis (A-frame style). The floating lid could accommodate snowshoes, although the lone attachment point for the lid doesn't inspire confidence.
We initially didn't think we'd use the large internal gear loop much outside of climbing applications. After extensive use, we found that being able to clip small bags, stuffed jackets, or even small electronics to the top of the inside of the pack made organizing the main compartment a lot easier.
While this pack is a bit large for commuting use, we didn't mind it while travelling. It could pack down while not fully loaded, and we liked the slight peace of mind that came from the water-resistant material (however, it is not waterproof!).
With plenty of attachment options, it can carry a wide variety of gear. However, we prefer having two side compression straps.
Ease of Use
This pack has been through some revisions over the years that have mostly improved its ease of use. The haul loops near the top of the pack make it easy to toss around in a car or clip to a belay. We liked the low side gear loops, which we were able to access easily with the pack on. If you like clipping things to the outside of your pack, the double daisy chains make it very easy.
Outside pockets provide decent organization. The top lid is big enough to carry plenty of clothing accessories, snacks, and small electronics. While the side pockets aren't accessible while wearing the pack, they close decently well and are big enough to hold gloves or a small to medium sized water bottle. We especially liked the durable fabric on the side pockets for carrying out wag bags when hiking in the desert southwest.
Unlike many other top-loading packs in this review, we found that the top lid refused to stay cinched down. The metal hook that holds the lid down is prone to slipping off when fully cinched down, letting the top lid flop around freely. While the other attachment points for the top lid are sleek and effective, we found this failure to be distracting while scrambling.
The multiple attachment points for ice axes work well, but if you like to carry hiking poles, consider a more day hiking oriented pack that has pole-specific carrying options.
The Mountain Hardwear Scrambler 35 is advertised as a durable pack, but after hiking in canyon country, we found the material lacking compared to other heavier backpack fabrics. While the material is stiff and hard to pull apart, it doesn't resist small punctures or abrasion as well as other packs in this review. We often find that stiffer fabrics such as those on the Scrambler are less puncture-resistant than more flexible fabrics because they can't distribute sharp impacts across much surface area.
After just one hike through a slot canyon in the Escalante region of Utah, we punctured 6 holes in the body of the pack, just from rubbing against sandstone walls. We have taken similar-sized packs with more commonly used nylon pack cloth down canyons with maybe some abrasion to show for it, but never this level of damage. Compared to thick, coated nylon, the light fabric of the Scrambler just doesn't hold up to wear very effectively.
While the pack fabric is water-resistant, it is not seam-sealed, and will let in water as a result. During our standard rain testing, barely any water made it through the top of the bag, but the bottom of the bag got soaked on the inside as water seeped through the seam between the body fabric and the thicker fabric on the bottom of the pack.
This pack is by no means waterproof, but the face fabric on the Scrambler sheds water nicely, and doesn't soak up much water at all, so it would perform well in wet environments with an internal liner to keep your gear dry.
The Scrambler crosses over between more technical sports like climbing and sports like hiking that benefit from feature-rich packs. If you need a pack for a wide range of activities, this might be the one for you. It's on the more expensive side, but if you can live with its faults, it delivers adequate performance.
The Mountain Hardwear Scrambler 35 performs well as a versatile, fast-and-light mountain pack. It suffers from somewhat poor durability and has some minor faults, but is overall an enjoyable pack to use. If you can manage a comfortable fit with the suspension, you'll have a pack that can carry a wide variety of gear and move with you in all but the most dynamic activities.
