105 mm Women's Big Mountain Freeride Ski
Black Crows Atris Birdie
Women who ski the whole mountain hard and want one pair to do it get the full Atris shape in a size run that starts at 160.2 cm. A 105 mm waist with a double rocker profile floats in fresh snow and pivots in trees, while classic medium camber underfoot on a 19 m radius holds an edge when the snow firms up. At 1,675 g per ski in the 166.3 cm, the Black Crows Atris Birdie is a substantial freeride ski rather than a lightened women's version, which is exactly the point.

Is This the Right Ski for You?
Best For
Advanced and expert women who want one 105 mm freeride ski for powder, trees and cut-up snow, and who ski 160 to 178 cm lengths on the whole mountain.
Consider Another Ski If
You want a lighter ski to tour on, a narrower ski for firm groomers, or a softer flex, since the Atris Birdie carries the same construction and flex as the men's Atris.

Why We Like It
- The Atris Birdie is the full Atris rather than a softened version, so a strong skier is not fighting a ski that gives out before she does.
- A 160.2 cm length at 134-105-120 mm means smaller skiers get a genuine 105 mm freeride ski instead of the bottom of a men's size run.
- A 19 m radius across the first three lengths keeps the Atris Birdie quick in trees and bumps while classic medium camber underfoot keeps the edge honest on firm snow.
- At 1,675 g per ski in the 166.3 cm, the Atris Birdie has enough mass to hold its line through cut-up afternoon snow.
Best Uses
- Storm days and soft snow in bounds
- Trees, bumps and natural features
- Cut-up afternoon snow at speed
- One-ski resort quivers at 105 mm
Ski Specialist's Advice
The first three lengths run a 19 m radius and only the 178.4 cm steps to 20 m, so the Atris Birdie stays quick across most of its run. Skiers at 5 foot 4 and under who ski trees and bumps do well on the 160.2 cm or 166.3 cm, and skiers over 5 foot 8 or anyone skiing fast on open terrain should look at the 172.1 cm or 178.4 cm. The 172.1 cm and 178.4 cm are dimensionally identical to the same lengths in the men's Atris.
Black Crows sets the mount at -8 cm from center with a 3.5 mm by 9 mm drilling pattern, marked with an arrow on the sidewall, and a 110 mm brake is the narrowest that clears the 105 mm waist. Because the Atris Birdie carries the same flex as the men's ski, we do not recommend softening the setup elsewhere to compensate; a lighter skier is better served by dropping a length than by fitting a softer binding.
Black Crows specifies a 1 degree base bevel and a 1.5 degree edge bevel on a sintered base. That is a flatter base bevel than the touring range uses and it favors edge engagement, which is worth keeping on a rockered 105 mm ski that already gives up effective edge to its shape.

Compare the Black Crows Atris Birdie
Atris Birdie vs. Black Crows Atris
The Atris Birdie and the Atris share dimensions, radius and weight at the 172.1 cm and 178.4 cm lengths. The Atris Birdie adds a 160.2 cm and 166.3 cm and drops the 184.3 cm and 190.2 cm. Size run and topsheet separate them rather than performance, so choose on length availability.

Atris Birdie vs. Blizzard Sheeva 10
Skiers cross-shop these two as women's freeride skis at 102 and 105 mm. The Sheeva 10 is the damper ski through cut-up snow, while the Atris Birdie runs more rocker and a more maneuverable feel at 105 mm. Choose by whether you value damping or quickness.

Common Questions
Who should buy the Black Crows Atris Birdie?
The Black Crows Atris Birdie suits advanced and expert women who want one 105 mm freeride ski for soft snow, trees and cut-up afternoons. With double rocker, classic medium camber underfoot and 1,675 g per ski at 166.3 cm, the Atris Birdie is built for skiers who push a ski rather than ride it.
What bindings work with the Black Crows Atris Birdie?
The Black Crows Atris Birdie takes standard alpine bindings, pin/tech (low-tech) touring bindings, and hybrid bindings, because a ski carries no sole norm of its own. Match the binding to your boot sole norm rather than to the ski, and confirm the binding accepts that norm. Black Crows sets the mount point at -8 cm from center and specifies a 3.5 mm by 9 mm drilling pattern. Choose a brake that clears the 105 mm waist, so 110 mm is the narrowest that works.
Is the Atris Birdie softer or lighter than the Atris?
No, and this is worth correcting because it is widely assumed. Black Crows states that its women's and men's ski lines differ only in topsheet design, with the Vertis Birdie as the single exception. The 172.1 cm and 178.4 cm lengths carry identical dimensions, radius and weight in both models. What the Atris Birdie changes is the size run: it adds a 160.2 cm and 166.3 cm and drops the 184.3 cm and 190.2 cm.
What length Black Crows Atris Birdie should I get?
The 160.2, 166.3 and 172.1 cm all run a 19 m radius and the 178.4 cm steps to 20 m. Skiers at 5 foot 4 and under who ski trees and bumps do well on the 160.2 cm or 166.3 cm, while skiers over 5 foot 8 or those skiing faster on open terrain should look at the 172.1 cm or 178.4 cm.
How much does the Black Crows Atris Birdie weigh?
The Atris Birdie weighs 1,625 g per ski at 160.2 cm, 1,675 g per ski at 166.3 cm, 1,800 g per ski at 172.1 cm and 1,950 g per ski at 178.4 cm. Those are per-ski figures, so double them before comparing against a listing that quotes a pair.
Can the Black Crows Atris Birdie be used for touring?
It can be mounted with a pin-tech binding, but it is not a touring ski. At 1,800 g per ski in the 172.1 cm the Atris Birdie costs real effort on a climb. Skiers who want a Black Crows ski with a similar footprint that is built to be skinned should look at the Navis Freebird at 104 mm and 1,475 g per ski.
Where does the Black Crows Atris Birdie mount?
Black Crows marks the mount at -8 cm from center with an arrow on the sidewall and specifies a 3.5 mm by 9 mm drilling pattern. The brand advises mounting on that line and states that customizing the mount point transfers responsibility for resulting damage to the owner.
How does the Black Crows Atris Birdie handle firm snow?
Classic medium camber underfoot with intermediate ski and snow contact gives the Atris Birdie usable grip for a rockered 105 mm ski, and the 19 m radius keeps turns manageable. On hard ice it will wash before a narrower ski does. Skiers whose days are mostly firm groomers should look at something under 90 mm instead.
Our Verdict
The Black Crows Atris Birdie is the men's Atris in a size run built for smaller skiers, and Black Crows is explicit that the two lines differ only in topsheet. That matters, because it means a 160.2 cm buyer gets the same double rocker shape, the same classic medium camber underfoot and the same firm flex as a 190.2 cm buyer, at 1,625 g per ski. For advanced and expert women who want one 105 mm ski for the whole resort and do not want a softened version of it, the Atris Birdie is the straightforward answer.
