Atomic Redster Q 7.8 Review: A Wide Carving Ski That Handles Softer Snow
The Atomic Redster Q 7.8 pairs an 84.5 mm waist with the Redster Q7 construction concept, adding Revoshock C, titanal laminates, and a slightly softer flex for versatile frontside carving.
Introduction
The Atomic Redster Q 7.8 is one of the two widest models in the Redster collection, measuring 84.5 mm underfoot. That number matters because the rest of the line is built around far narrower platforms, with the narrowest Redster X9S sitting at 65.5 mm underfoot. The Q 7.8 therefore represents the wide end of a carving-focused family, and it deliberately blurs the boundary between a frontside ski and an all-mountain ski.
The construction follows the same blueprint as the narrower Redster Q7, simply on a wider platform. A power wood core is combined with titanal laminates and Revoshock C, the lighter of the two Revoshock systems. Compared with the heavier Revoshock S, this setup reacts a little more quickly to skier input while offering less damping. Atomic’s Ultra Wall concept also carries over, reinforcing the sidewall directly underfoot.

The core is not quite as thick as what you would find in a Redster G9 or a Redster X9S, which translates into a slightly softer flex pattern. Combined with the wider waist, that softer flex is the main reason the Q 7.8 holds up better than its narrower siblings once the snow stops being firm. There is also just a touch of early taper at the tip and tail, a subtle shaping change that helps the extremities release more easily.
Who This Ski Is For
This is a ski for people who carve. If most of your day is spent on firm, groomed runs and you want a platform that still behaves when conditions soften, the Q 7.8 fits that brief closely. It is approachable for an intermediate skier with reasonably accomplished technique, and it has enough headroom for advanced and expert skiers who prefer a lighter, more responsive ride over a heavier, more damp one.
The comparison that matters most is with the Redster Q 9.8. That ski is heavier and stiffer, and it asks a little more of the person on top of it. The Q 7.8 sits a step below in that regard, which makes it easier to manage for a broader range of skiers without feeling like a compromise for stronger ones. At that point the choice comes down to skiing style and personal preference rather than outright ability.
It is also worth being clear about who it is not for. Skiers who rank moguls above frontside carving will find better-matched options elsewhere in the category. The Q 7.8 can be taken into bumps, but it still reads as a carving ski rather than a genuinely versatile all-mountain tool.
Main Strengths
Grip and edge hold are the headline. With basically a hundred percent camber underfoot, titanal laminates, and the Ultra Wall sidewall reinforcement underfoot, the Q 7.8 holds an edge on hardpack with the confidence you would expect from a much narrower ski. That combination is what lets an 84.5 mm platform carve the way it does.
Turn shape is predictable and consistent with the rest of the Q family. At 173 cm the ski carries a 14.4 meter turn radius, and the turn radius figures match the Q7 models across the range. That consistency makes the transition between lengths feel intuitive rather than like learning a new ski.

Response is the other standout. Revoshock C is the lighter of Atomic’s two systems, and it gives the ski a quick, lively reaction to skier input. The trade-off is less damping than a Revoshock S build, but for many skiers that trade is a good one, because the ski stays energetic instead of feeling planted and heavy.
Things to Consider Before Buying
The most important thing to understand is that this is not a true all-mountain ski, despite the width. The Q 7.8 does quite well in softer snow, and the wider waist clearly helps there, but it still feels more like a carving ski than a versatile freeride-oriented platform.
Damping is the second consideration. Because Revoshock C is lighter than Revoshock S, the ski is a touch more responsive and a touch less damp. Skiers who prioritize a heavy, planted feel on icy groomers may prefer a different build in the line.
Flex is the third. The core is not as thick as the G9 or X9S, so the flex pattern is slightly softer. That is a benefit in soft snow and a consideration for very aggressive skiers who want maximum torsional rigidity underfoot.
Performance in Softer Snow and Packed Powder
This is where the Q 7.8 separates itself from the narrower Redster models. The wider 84.5 mm waist, the slightly softer flex, and the subtle tip and tail shaping work together to keep the ski composed when the surface is not perfectly firm. It handles softer snow conditions well, and it does not feel like it is fighting the terrain.

Packed powder is a particularly strong application. On western trails, where softer snow is the norm rather than the exception, the Q 7.8 makes a convincing case as a carving-focused daily driver. There is a reasonable argument that it handles packed powder better than the narrower Redster Q7, purely because of the extra width and the more forgiving flex.
Moguls and other soft-snow terrain remain usable, just not the ski’s priority. If carving on firm groomed runs is the focus, with occasional excursions into bumps and softer snow, the Q 7.8 covers that range comfortably.
How It Compares Within the Redster Line
Placement in the lineup is straightforward. The Redster X9S is the narrowest option at 65.5 mm underfoot and sits at the carving end of the spectrum. The Redster Q7 uses the same construction and shaping concept as the Q 7.8 on a narrower platform. The Redster Q 9.8 steps up in weight and stiffness, delivering more damping and a more demanding ride.
The Q 7.8 lands between those poles. It is wider than the Q7 and more forgiving than the Q 9.8, which makes it the natural pick for a skier who wants carving performance with a little more surface area and a slightly softer, more responsive feel. The shared turn radius figures across the Q models mean the differences come down to width, flex, and damping rather than a completely different turn character.
Buying Advice
Match the ski to the snow you actually ski most. If your home mountain is typically firm and icy, the Q 7.8 still delivers strong edge hold, and the extra width costs very little in carving precision. If you regularly ski softer trails and packed powder, the width and softer flex become clear advantages rather than a compromise.
Match it to your technique and temperament as well. An intermediate skier with solid fundamentals will find the Q 7.8 manageable and confidence-building. Advanced and expert skiers who like a quick, responsive ski will enjoy it, while those who want maximum damping and weight should look at the stiffer option in the line.

Length choice deserves a moment of thought. The 173 cm version carries a 14.4 meter turn radius, and the radius scales with length across the Q family, so the size you pick shapes how tight the ski wants to turn. Choose based on the turn shape you prefer and the terrain you ski most, not purely on height.
Conclusion
The Atomic Redster Q 7.8 is a carving ski with an unusually wide footprint, and that is precisely its appeal. It brings the Redster Q7 construction concept to an 84.5 mm platform, adds the lighter Revoshock C system for quicker response, and uses a slightly softer flex to stay composed in softer snow.
It is not a dedicated all-mountain ski, and it is not the most damp option in the range. For skiers whose days revolve around firm groomed runs, with room for packed powder and the occasional bump line, it is a well-rounded and genuinely versatile choice.
