OGSO Big — Review

The OGSO Big is the Chamonix boutique's big-mountain progressive freeride ski, sitting at the top of their Free Ride Series with a 108-114 mm waist range. It uses EXALTED camber, Titanal reinforcement, and OGSO's torsion and tip stabilizers. Verified sidecut per length: 136-108-123 mm at 170 cm (20 m radius, 1600 g), 139-110-126 mm at 178 cm (21 m, 1750 g), 142-112-129 mm at 186 cm (22 m, 1900 g), 145-114-132 mm at 194 cm (23 m, 2050 g).

At 108-114 mm underfoot with Titanal reinforcement and a 20-23 m radius, the Big is unambiguously a big-mountain freeride tool. Weights of 1600-2050 g per single ski are competitive for the segment. The EXALTED camber with high nose surfs powder, slashes steep chutes and threads tight trees at high speed. On piste, the long radius and wide waist make it a lazy carver — not a use case. Off piste in deep and variable snow, it delivers the power and stability typical of Titanal-reinforced freeride.

Core: mixed wood core with Titanal reinforcement, torsion stabilizer and tip stabilizer for edge control at high speed. EXALTED camber with high nose, moderate 3 mm underfoot camber and long tip (505 mm tip length, 81 mm tip height). Sidecut and radius progress per length (see above). Available lengths 170, 178, 186 and 194 cm. Manufactured at Kästle CZ.

Compared to the Blizzard Rustler 11 the Big is similar in intent but boutique-manufactured with OGSO's stabilizer package. Against the Nordica Enforcer 110 free it is comparable in waist and Titanal reinforcement — the Nordica is a mainstream reference, the OGSO a Chamonix-designed alternative. Compared to the wider OGSO Grizzly at 106 mm, the Big is 4-8 mm wider and more powder-first.

Pros

• Verified per-length data across all four lengths (dimensions, radius, weight).
• Titanal reinforcement plus stabilizers deliver stability and edge control at high speed.
• EXALTED camber with high nose surfs powder and slashes steep terrain.
• Four length options (170-194 cm) suit shorter-to-taller advanced skiers.

Cons

• 108-114 mm waist and long radius make on-piste use tedious.
• Not built for touring — resort-oriented weight and construction.
• Premium boutique pricing versus mainstream 110 mm freeride skis.
• Requires committed technique to unlock the Titanal reinforcement.

Verdict: A boutique Chamonix-designed 110 mm big-mountain progressive freeride ski for advanced-to-expert skiers who see real powder and steep terrain. Best matched to open big-mountain lines and skiers who charge through variable snow.
