Sego Wave BC 104 — Review

The Sego Wave BC 104 is the versatile mid-fat tourer in Sego Ski Co.'s hand-built backcountry range, made in Victor, Idaho. With a 104mm waist it lands in the sweet spot for a one-ski touring quiver: wide enough to float soft snow, narrow enough to stay light and quick edge-to-edge. The whole point of this ski is efficiency without giving up the down. At weights as low as roughly 1375 g per ski it climbs like a dedicated tourer, yet the extra width and edge let you ski powder and variable conditions with real confidence.

On the up, the Wave BC 104 feels light and willing. The low swing weight makes kick-turns easy and long skin tracks far less tiring than a heavier resort ski would be. On the down, the 104mm platform floats surprisingly well in fresh and cold smoke, and the tip rocker keeps the shovel from diving in deeper snow. Underfoot camber gives you a defined edge for firm skin-track descents, spring corn and the inevitable variable snow you meet in the backcountry. It is a ski that rewards a centered, dynamic stance rather than brute force. Push it in soft snow and it planes; ease off and it drifts and pivots happily through tight terrain. The turn radius runs long, from 20.5m at 157cm out to 26m at 185cm, so it prefers medium-to-large arcs and open faces over slalom-tight trees.

The Wave BC 104 uses a light full wood core with UHMW sidewalls — a construction that keeps grams down while retaining enough torsional life to hold an edge. The sidecut measures 135/104/115mm, a mid-fat profile with a generous shovel for float and a moderate tail. Profile is tip rocker with camber underfoot: the classic backcountry touring shape that balances powder float against firm-snow grip. Lengths run 157, 165, 175, 181 and 185cm, with per-ski weights of 1375, 1480, 1550, 1650 and 1700 g respectively, and turn radii of 20.5, 22, 23.5, 24.5 and 26m. The weights are genuinely low for a 104mm ski, which is exactly where this shape earns its keep.

This is a ski for the human-powered skier who wants one board for most days: efficient climbing plus enough width to enjoy powder and manage variable snow. If you want a touring-oriented alternative, the Atomic Backland 107 offers similar float with a slightly wider platform, while the DPS Pagoda Tour CFL 105 trades some grams for carbon-laminate liveliness. The Armada Locator 104 is a close width match with a more all-mountain lean. Within Sego's own line, step down to the Sego Wave BC 94 for a lighter, more efficient climber, or up to the Sego Wave BC 112 for deeper-day float.

Pros

• Genuinely light for a 104mm ski, so it climbs efficiently.
• 104mm width with tip rocker floats soft snow well.
• Underfoot camber gives dependable grip on firm skin tracks.
• Hand-built full wood core with a versatile mid-fat shape.
• Balanced one-ski touring quiver for most backcountry days.

Cons

• The light build gives up damping and stability versus heavier skis in chop.
• Touring-first design, not a resort charger.
• Long turn radius feels less nimble in tight trees.

Verdict: The Sego Wave BC 104 is a smartly balanced backcountry all-rounder that prioritizes efficient climbing without giving up too much on the descent. Its low weight and 104mm rockered-camber shape make it an excellent one-ski touring choice for skiers who value float and grip over resort-grade damping. If you spend most of your days earning turns and want a single versatile mid-fat, it belongs on your shortlist.
