Bestseller · 417 reviews · ★ 4.9

Flight Deck Boxer Brief

The one most pilots buy first. A six-inch inseam that holds position through a full duty day, a horizontal-entry pouch that stays put in a harness, and a waistband that does not print through uniform trousers.

Rotation Brief

For pilots who want nothing below the trouser line. Lighter at 180 gsm, cut high on the leg, and finished with a 28 mm waistband that disappears under a fitted uniform.

TRUE NORTH Longhaul Compression Sock in merino wool, gold compass mark on the cuff
284 reviews · ★ 4.7

Longhaul Compression Sock

Graduated 15–20 mmHg — the range clinicians recommend for prolonged seated travel. Merino blend so it manages sweat inside a leather flight boot, with a seamless toe and a reinforced heel that survives hotel laundry.

$44 single · $118 three-pack (save $14)

Compression garments are a comfort product, not a medical device. If you have a circulatory condition or a history of DVT, speak to your AME before flying in graduated compression.

Rotation bundles

Kit out a full trip.

Built around real duty patterns. Every bundle ships in a flat pack that fits a flight-bag side pocket.
