Supair ALP – Ultralight Hike & Fly Race Harness

The Supair ALP is an ultralight, aerodynamic pod harness built for high-level hike & fly and hike & fly racing. From just 1.58 kg (3.5 lb) including all accessories, it combines a full-body “submarine” fairing with an inflatable protector – bringing the performance of cross-country competition harnesses to athletes who carry everything on their back.

Supair’s designers tested more than 30 harness configurations and 30 envelope designs, in flight and with CFD (computational fluid dynamics), to find the best balance between aerodynamics, weight and ease of use. In Supair’s comparative studies, a full-body envelope like the ALP’s performed almost twice as well aerodynamically as a standard lightweight pod harness.

Who is the ALP for?

• Hike & fly racers – Supair pilot Pierre Rémy flew the ALP at the X-Pyr 2024
• High-level XC pilots who walk to launch and want competition-style glide
• Weight-obsessed adventurers who still want aerodynamic performance

The ALP is designed exclusively for hike & fly and cross-country flying by experienced pilots. Acro is not allowed – the frame is not designed for high G-loads.

Understanding your ALP

A full-body aerodynamic envelope

The ALP’s envelope wraps the whole pilot like a submarine. It takes shape in flight using the relative wind, reducing the pilot’s drag and stabilizing the harness in yaw – so more of your wing’s performance turns into glide.

Magnetic zipper

The pod closes by magnetic force alone when you straighten your legs, creating an airtight seal so the envelope can inflate. To get out, just slide a foot out or bend your legs and spread your knees – no fiddling with zips before landing.

Inflatable protector

The ALP’s protector takes up no space in your pack. It inflates in seconds at takeoff through a tube on your left shoulder, and deflates completely for storage. It includes an inflatable sub-base.

Cockpit

• Reach your instruments in flight without unzipping anything
• Removable clear visor
• Zipped pocket and cable opening for a power bank to keep your instruments charged

Hammock frame and adjustments

The frame is a hammock design with no crossbar, reinforced at the back with a fiberglass rod. You can adjust shoulder length, backrest angle, seat angle, lumbar support and speedbag length.

Storage for race days

• Back pocket: 12 L (S), 13 L (M), 15 L (L), with a hose passage
• 3 L under-seat pocket
• Pole holder for hiking poles
• Two bottle pockets
• Battery compartment under the cockpit

Frequently asked questions

Who is the ALP for?

Experienced hike & fly and high-level cross-country pilots, especially in competition. If you want a lighter all-rounder that’s easier to live with, look at the STRIKE 3; for a pressurized XC harness with more comfort, see the PULSE.

How much does the ALP weigh?

1.58 kg (S), 1.61 kg (M) and 1.64 kg (L) – including all accessories.

Which ALP size should I choose?

S fits pilots 155–175 cm (5’1″–5’9″), M fits 172–185 cm (5’8″–6’1″) and L fits 182–195 cm (6’0″–6’5″). Check the weight ranges in the Specifications tab, and send us your height and weight if you’re between sizes:  WhatsApp · ✉️ Email · 📞 (917) 359-6449

Which reserve fits the ALP?

Reserves from 2 to 4.8 L.

How does the fairing work?

The envelope is shaped by the relative wind in flight, reducing drag and stabilizing the harness in yaw. The inflatable protector can be fully deflated for storage.

Can I return or exchange the ALP?

Harnesses are final sale, but you can exchange your ALP for a different size. Ask for our free expert advice before you order:  WhatsApp · ✉️ Email · 📞 (917) 359-6449. See the Shipping & Returns tab for details.
