A long nose and the wish for tight, flowing turns: Prior makes that a deliberate powder concept with the Fissile. Comparing only total length with a conventional all-rounder can be misleading. Much of this board sits ahead of the area working on firm snow.
Is the Prior Fissile Split 26/27 right for you?
26/27 season guide: the version currently offered by the manufacturer.
Which type of splitboarder does it suit?
Freeride splitters who deliberately want a long powder nose. You want the long-nose concept and accept extra overall length on the approach. That makes the Fissile relevant. If compact handling and repeated tight kick turns define your tours, examine that compromise particularly carefully.
What does the shape offer on the descent?
Prior gives a tight 6.5 m radius and recommends riding the Fissile around 8 to 10 cm longer than your usual board. That advice belongs to its elongated nose, not to splitboards generally. It explains why the range starts at 161 cm. If you want long, open powder turns the concept deserves attention; if repeated quick changes in confined terrain are common, put the more compact Slasher alongside it.
What should you consider on the skin track?
The length is still real on the ascent, even when part of the nose has little contact on hard snow. Consider kick turns, carrying sections and attachment to your pack. Suitable skin fittings and enough space around the tail matter too. The Fissile is a deliberate powder-touring choice, not a way of making every possible tour easier with extra length.
How do you choose the right size and setup?
Current sizes are 161, 166, 172 and 178 cm. Compare effective edge and area as well as total length with your existing board. The public page does not provide a complete numerical size table, so confirm the measurements with Prior before ordering rather than applying the 8-to-10 cm recommendation blindly.
Configuration is part of buying a Prior. The shown figure is the starting price; XTC Carbon, particular connectors, topsheets, bases or other requests can change the total. Prior claims an average saving of around 500 grams against Quad-glass. That is a general manufacturer figure, not a weight prediction for your individual size.
Choose shape, length and width first, then construction and connectors that suit your binding interface. A custom graphic does not automatically change flex. For a Canadian order, confirm lead time, shipping and the full delivered amount for your country. A euro display establishes currency, not European warehouse stock or a final price including every import cost.
How should boots, bindings and board work together?
Boot and highback choice still matters as much as the long nose. On firm traverses, a supportive cuff helps transmit pressure through the binding to the edge. Choose a very soft complete setup only when you accept its limits on your usual tours.
The manufacturer’s recommendation to size up belongs to this shape. It is not a general powder-board rule or standard advice for learning to splitboard.

Which test experience helps you choose?
We have not yet tested the Prior Fissile Split ourselves. The advice on this page is based on manufacturer information and the principles in our Gear Guide. We therefore cannot yet describe the feel of this exact board from personal riding experience.
On a demo, we would focus on the points discussed above for your riding style: can your boots put enough pressure on the edge, does the board remain comfortable to move after a longer climb, and does the size work when the snow becomes heavier lower down? Use your usual boots where possible and compare a suitable length.
What has changed since 25/26 and earlier models?
Prior currently sells this shape through its custom configurator without unambiguously assigning model year 26/27 on the product page. This is our guide for the 26/27 season, not a claim of a newly developed annual version. Compare older offers by length, width, Quad or XTC construction and installed hardware; a different price or custom graphic alone does not establish a changed shape.
Earlier model page in the archive: Prior Fissile XTC 17-18.
Which other current boards fit your riding style?
Compare Prior Spearhead Split and Prior Slasher Split. The shape and usage differences are discussed above. For a demo, similar sizing, your own boots and a familiar stance help more than comparing random available lengths.
FAQ: What should you know before your first tour?
Do I really have to buy the Fissile longer?
Prior suggests approximately 8 to 10 cm extra because of the long nose. Treat that as a starting point for sizing advice rather than an obligation. Rider weight, boot width and handling on your approaches should determine the final size.
Which Prior Fissile Split size should I choose?
Currently listed sizes are 161, 166, 172, 178. Current sizes are 161, 166, 172 and 178 cm. Compare effective edge and area as well as total length with your existing board. The public page does not provide a complete numerical size table, so confirm the measurements with Prior before ordering rather than applying the 8-to-10 cm recommendation blindly.
What hands-on test experience is available?
We have not yet tested the Prior Fissile Split ourselves. Our assessment is based on manufacturer information and our Gear Guide. We do not assign our own riding scores to it.
Which current alternatives should I compare?
Prior Spearhead Split and Prior Slasher Split are the relevant comparisons discussed on this page. Choose shape, boot fit and your usual tours first. A different construction level becomes useful after those basics fit.
Which boots and bindings suit this board?
Boot and highback choice still matters as much as the long nose. On firm traverses, a supportive cuff helps transmit pressure through the binding to the edge. Choose a very soft complete setup only when you accept its limits on your usual tours.
Is this a new construction for 26/27?
Prior currently offers the shape without an unambiguous 26/27 model-year label. This is our seasonal guide. The actual configuration matters more than the year alone.
Which sizes and specifications are available?
These are manufacturer specifications, not our own measurements. The current configurator does not provide a complete public dimensional table. Confirm waist, effective edge and rider-weight range directly with Prior before ordering.
Which measurements and sizes does the manufacturer specify?
| Length (cm) | Profile |
|---|---|
| 161 | Powder Rocker |
| 166 | Powder Rocker |
| 172 | Powder Rocker |
| 178 | Powder Rocker |
