Dynafit Blacklight 88 Flex 90 Touring Ski

Dynafit Blacklight 88 Flex 90 Touring Ski

The stiffer Blacklight 88 for powerful descents without giving up a lightweight approach. The Dynafit Blacklight 88 Flex 90 is designed for ambitious backcountry skiers who want to travel efficiently uphill and still drive a ski with confidence on the way back down. Built around a lightweight Paulownia core and carbon construction, it offers the weight savings of a speed-oriented touring setup with the more supportive flex of Dynafit's Flex 90 layup.

This is the Flex 90—not the Flex 70. Both share the Blacklight 88 shape and intended touring character, but the Flex 90 has a stiffer layup, distinct manufacturer style number and a slightly higher weight in every length. That extra support is designed for skiers who apply more pressure through the shovel, prefer a firmer feel, or ski faster and more assertively in variable alpine snow. The softer, lighter Flex 70 is a different model and should not be treated as an interchangeable color or size option.

Why choose the Blacklight 88 Flex 90?

• Efficient touring weight: from 970 g per ski in 151 cm to 1,230 g in 184 cm, depending on length.
• Supportive Flex 90 construction: a more powerful feel than the Flex 70 for decisive turning and stronger downhill input.
• Paulownia wood core: keeps ski weight low for sustained climbs and longer approaches.
• Carbon reinforcement: Dynafit's Full Carbon Technology aims for stability and efficient energy transfer without unnecessary mass.
• 3D Sidewall-Cap construction: balances edge performance with lightweight touring design.
• Tip and tail rocker: helps the ski maneuver through mixed terrain and makes it easier to initiate turns away from groomed snow.
• Touring-focused waist: nominally 88 mm, with the actual waist varying from 85 to 90 mm according to length.

How it compares with Flex 70

At 172 cm, the Flex 90 weighs approximately 1,130 g per ski; the corresponding Flex 70 weighs approximately 1,090 g. Both use a 122–88–110 mm sidecut and an 18.7 m turn radius at that length. Flex 90 is the more supportive option, while Flex 70 favors skiers who want a softer and lighter ride. Choose based on skiing style, weight sensitivity and how much power you bring to your turns—not simply the shared Blacklight 88 name.

Which length should I choose?

Dynafit offers six lengths: 151, 158, 165, 172, 178 and 184 cm. The radius, weight, sidecut and rocker length vary across the range, so an 88 mm model name does not mean every length measures exactly 88 mm underfoot. For example, the 172 cm ski measures 122–88–110 mm with an 18.7 m radius, while the 178 cm measures 123–89–111 mm with a 20 m radius. Ski length should reflect your height, experience, preferred terrain and the balance you want between maneuverability and stability.

CCBB shop advice: this is a strong direction for experienced skiers seeking efficient ascents and precise downhill handling. Match the length to your skiing style and have an appropriately compatible touring binding mounted by a qualified technician. Ask the shop about skin compatibility and your intended conditions before completing a setup.
