Updated for the 25/26 season
The Weston Eclipse Split is the Backwoods shape scaled for smaller-footed and lighter riders. A tapered directional freeride board with a wide rockered nose, quasi-swallowtail tail, and camber underfoot — three sizes (145, 150, 155 cm) covering riders from around 39 to 84 kg. Backcountry Magazine Editor’s Select 2022. Artwork by Shannon Kennedy. Manufactured at GP87 in Colorado.
Who is the Weston Eclipse Split for?
The Eclipse Split is built for lighter and smaller-footed riders who want the same freeride DNA as the Backwoods in a shorter, lighter package. Boot sizes up to US 11 (women) or US 10 (men). It is not a beginner board — the flex 7/10 and directional shape reward confident riding. But it punches above its weight in technical terrain and is a legitimate tool for serious backcountry use.
Three sizes cover a narrower weight range (39–84 kg) than the Backwoods. If your weight is above 84 kg, look at the Backwoods Split instead.

Shape: Quasi-Swallowtail + Camber
The Eclipse combines a wide, blunt powder nose with a subtle quasi-swallowtail tail — not as extreme as the Japow’s full swallowtail, but enough to reduce tail volume and encourage float without sacrificing edge hold. Camber underfoot keeps the board locked in on sidehills and firm terrain. The 18 mm nose-to-tail taper narrows the board progressively, making directional turns fluid and reducing the effective edge length in tight terrain.
The Tip to Tail Carbon Stringers add torsional stiffness — on a board this size, that stiffness translates to direct response in hard-carving turns, preventing the board from washing out when you push it.
Ride Feel
Smaller boards are faster in tight terrain — the Eclipse moves edge-to-edge quickly, initiates turns easily, and tracks well through variable snow. The quasi-swallowtail helps in powder by sinking the tail naturally, though it is less dramatic than a full swallowtail shape. In mixed conditions (the powder turns to variable crust halfway down), the camber and slightly narrower waist keep you in control where a pure powder shape would struggle.
At flex 7/10 it is not soft — but on a lighter board, the same flex number feels more responsive than on a heavier one. Lighter riders will find it punchy and direct. Heavier riders at the top of the weight range (75–84 kg on the 155) will feel more of the stiffness.
Uphill Performance
The Eclipse is one of the lighter splitboards in Weston’s lineup: 2800 g for the 145, 3080 g for the 150, 3310 g for the 155. On long tours, that weight difference is tangible. The Karakoram UltraClip 2.1 (the newest version) transitions quickly, and the shifted touring bracket makes kick turns more natural on steep approaches.
Skin compatibility: Skin 1 for 145, Skin 2 for 150, Skin 3 for 155. The holeless base avoids drag on flat exit glide.
Eclipse vs. Backwoods: Which to Choose?
The Eclipse is the Backwoods for riders who need smaller sizes (145–155 cm) and lighter weight. The shape and construction are nearly identical — the key differences are: Eclipse uses PU sidewalls (vs UHMW on Backwoods), the UltraClip 2.1 (vs 2.0), and the quasi-swallowtail tail (vs standard directional). If you are between the two size ranges, the Eclipse’s lighter weight and tail shape give a slight advantage in powder and on long tours.
Verdict: Weston Eclipse Split
If you are a lighter or smaller-footed splitboarder who has been forced to size up into boards that feel unwieldy — the Eclipse was built for you. It delivers legitimate freeride performance in a package sized for the rider, not the other way around. Backcountry Magazine’s Editor’s Select 2022 confirms it holds up at a competitive level.
Not the right board if you weigh over 85 kg (see Backwoods Split) or if your primary use case is deep powder (see Japow Split). For mixed-terrain, all-condition freeride use in smaller sizes, the Eclipse is Weston’s strongest option.

Frequently Asked Questions
Is the Eclipse Split only for women?
No — Weston explicitly designs it for any rider who fits the size range. Boot sizes up to US 10 (men) or US 11 (women), weight up to 84 kg. If you fit those parameters and want a freeride board, the Eclipse is a legitimate choice regardless of gender.
What size Eclipse Split should I ride?
145 cm for 39–66 kg riders (height 150–160 cm), 150 cm for 48–75 kg (157–173 cm), 155 cm for 57–84 kg (170–180 cm). If you are between sizes, go longer for more float in powder and stability on steeps; go shorter for faster edge-to-edge and tighter terrain.
How does the Eclipse differ from the Backwoods Split?
Same freeride DNA, different size range and a few material differences. Eclipse runs 145–155 cm for lighter/smaller-footed riders; Backwoods runs 157–167W for larger riders. Eclipse has PU sidewalls and Karakoram UltraClip 2.1; Backwoods has UHMW sidewalls and UltraClip 2.0. Eclipse also has a subtle quasi-swallowtail; Backwoods has a standard directional tail.
