hy 13 free vs duke pt 16

The ATK HY Free is the all-metal lightweight; the Duke PT 16 is the burliest resort-charging convertible — opposite ends of the same category.

The ATK HY Free 13 and Marker Duke PT 16 are both convertible hybrids — alpine toe in ski mode, tech-pin toe in tour mode — but they live at opposite ends of the category's weight and downhill-power spectrum. The HY Free is the lightest hybrid available (~675 g/binding); the Duke PT 16 is the heaviest and burliest (~1,050 g uphill, ~1,350 g downhill). The decision between them is mostly about how much weight you're willing to carry for how much downhill margin.

Downhill: the Duke PT 16 has decisively more reserve

The Duke PT 16 runs Marker's Jester-derived alpine toe with full DIN-certified elastic travel and a DIN 16 ceiling. The HY Free 13 has a real alpine toe — rare in the lightweight space — but the elastic envelope is smaller and the DIN ceiling is 13. ATK is explicit that the HY Free is not TÜV-certified (they told Skimo Co there are "no current plans" to certify it). For 95+ kg skiers, pushing DIN 13+ regularly, or repeated heavy compressions on big-mountain lines, the Duke PT 16 has measurably more margin. For most skiers under 90 kg the HY Free's downhill is excellent — but the gap at the top end is decisive.

Touring: the HY Free is ~375 g/binding lighter

HY Free 13 uphill weight: ~675 g/binding. Duke PT 16 uphill: ~1,050 g/binding (with the alpine toe detached and carried). That ~750 g/pair gap is substantial — and the HY Free's transition is simpler: alpine toe flips out of the way, tech toe takes over, no parts to stash in your pack. The Duke PT requires unscrewing the alpine toe with the included tool, putting it in your bag, and bolting on the touring toe; reverse at the top. For 25+ tour days a year, the HY Free returns weight and time at every transition.

Safety: the Duke PT 16's DIN/TÜV cert is the cleanest distinction

Duke PT 16: DIN/TÜV-certified ISO 5355 in alpine mode. HY Free 13: ATK publishes reference release values but explicitly not TÜV-certified. ATK's release calibration is widely respected — experienced freeriders trust it without hesitation — but for race insurance, guides, or certification-required contexts, only the Duke PT 16 qualifies.

Versatility: tied in alpine mode, both pin-only on tour

Both alpine toes accept ISO 5355 + GripWalk. Both touring toes are pin-only. Both support a one-ski-two-boots workflow in alpine mode, but in practice the HY Free is positioned and used almost exclusively with tech-insert touring boots given its lightweight intent. The Duke PT 16 is more often paired with both boot types.

Durability: tied

ATK's all-metal machined construction is benchmark — among the most durable bindings in the lightweight category. The Duke PT 16's metal-heavy construction is similarly durable in the heavyweight category. Different approaches, comparable long-term wear resistance. Neither is the binding that fails.

Pick by how much downhill margin you actually need

Pick the HY Free 13 if you tour 25+ days a year, weigh under ~90 kg, and don't need TÜV certification — the weight savings are substantial and the downhill performance is enough for the vast majority of freeriders. Pick the Duke PT 16 if you're 80% resort / 20% sidecountry, weigh 95+ kg or ski at DIN 13+, need the certification, or just want the most downhill-confident binding in the category. These two bindings target the same skier-type from opposite priorities — the answer depends on whether you value uphill efficiency or maximum downhill reserve.
