When picking out a backcountry ski or splitboard, there’s a lot to consider—shape, flex, width, weight—but one factor that often gets overlooked is construction. Yet, the way a ski or board is built has a huge impact on how it tours, rides, and holds up in the long run.

At the core of this decision is the debate… cap vs sidewall construction. Cap construction is prized for its lightweight efficiency and smooth flex, while sidewall construction offers maximum edge hold and a powerful downhill feel. Some brands stick to just one method, but at Voile, we build both—because the right choice depends on your terrain, your riding style, and what you prioritize in the backcountry.

So, how do you decide? This guide breaks it all down, helping you find the best fit for your next adventure.

Cap vs. Sidewall: A Simple Breakdown

At a glance, the cap vs sidewall construction debate might not seem all that intense—but the way a ski or splitboard is built directly impacts its weight, flex, durability, and performance in the backcountry. Here’s how they stack up:

Cap Construction

• The top layer wraps over the core, seamlessly connecting to the base.
• Results in a lighter, more forgiving flex that’s ideal for long tours.
• Less material means a slight weight advantage, making uphill travel more efficient.
• Increased durability against chipping and delamination—a major perk for backcountry riders who spend a lot of time in unpredictable conditions.

Sidewall Construction

• Uses vertical sidewalls that run along the edges of the ski or board.
• Creates a stiffer, torsionally rigid ride—ideal for aggressive downhill performance.
• Sidewalls help drive more power into turns, especially in firm or technical terrain.
• Heavier than cap construction, but some riders prefer the planted, powerful feel.

Hybrid Construction

• A mix of both, combining cap and sidewall elements.
• Offers a balance of lightweight touring efficiency with increased edge hold for descents.
• A great choice if you like versatility without committing to one extreme.

When to Choose Cap Construction

Cap construction shines in the backcountry for one big reason: weight savings without sacrificing performance. If you value efficiency on the skintrack and a smooth, intuitive ride on the descent, cap might be the way to go.

Cap construction is a great choice if:

• You prioritize uphill efficiency—cap skis and splitboards are lighter, making long tours easier.
• You want a responsive, nimble feel that doesn’t feel overly stiff or punishing in variable conditions.
• You ride in soft snow or mixed conditions, where a slightly more forgiving flex can help.
• You trust Voile’s track record of durability—our cap construction isn’t fragile, and it won’t quit on you.

When to Choose Sidewall Construction

If your backcountry missions lean toward big lines, technical descents, or firm snow, you might want the added torsional stiffness and edge hold that comes with sidewall construction.

Sidewall is a great choice if:

• You mostly ride or ski steep, technical terrain, where maximum edge hold is essential.
• You want a stiffer, more powerful feel for driving energy into your turns.
• You ride in variable or hardpack conditions, where additional torsional stiffness helps keep things stable.
• You just prefer the feel of a sidewall-style ski or board—and want a bit of that extra grip and dampness.

Looking for Something in Between? Try Hybrid Construction

If you like the touring efficiency of cap construction but want a bit more stiffness and edge hold, hybrid cap construction might be your best bet.

• This design blends cap construction in the tip and tail with sidewall elements underfoot, creating a ski that stays light on the uphill but grips harder on the descent.
• Voile’s Charger ACE and Vector ACE use this method to give riders the best of both worlds.

Voile Gives You Options

No two riders are the same, and neither are their needs in the backcountry. That’s why Voile builds skis and splitboards with cap, hybrid, and sidewall construction—giving you the freedom to choose what works best for your adventures.

• If you want the lightest possible touring setup, our cap construction models are the way to go.
• If you like a balance of uphill efficiency and edge hold, our hybrid cap construction skis provide that versatility.
• If you need the most aggressive, powerful ride, our sidewall splitboards offer maximum downhill performance.

Wherever you go in the mountains, we make sure you have the right tools to get there.
