Performance-oriented climbers pay attention! The super lightweight and comfortable Hirundos is perfect for all ambitious climbers who want to push their performance limits. Simple and sleek in design, equipped with four gear loops and constructed with Fuseframe technology, this harness brings everything you want. For precise waist belt adjustment, the Hirundos features a DoubleBack HD buckle. Fusefram TechnologyThis design uses thin thermoformed foam and dual-band construction on the inside of the hipbelt to increase comfort and reduce weight. The band construction of the hipbelt and leg loops, as well as the reinforcing elements (attachment of the gear loops), are incorporated into the foam to prevent pressure points on the inserts. In addition, the foam of the hip belt is coated with a fine fabric to ensure optimal pressure distribution. Thanks to these details, the outside of the climbing harness is a smooth, sleek, transition-free surface that ensures maximum abrasion resistance. The climbing harnesses equipped with Fuseframe technology have a sleek, high-quality, compact and comfortable design.Size &amp, WeightXS = Weight: 260 g, waist circumference: 65 - 71 cm, thigh circumference: 48 -53 cmS = Weight: 280 g, waist circumference: 71 - 77 cm, thigh circumference: 48 -53 cmM = Weight: 300 g, waist circumference: 77 - 84 cm, thigh circumference: 52 -57 cmL = Weight: 320 g, waist circumference: 84 - 92 cm, thigh circumference: 55 -60 cmXL = Weight: 340 g, waist circumference: 92 - 100 cm, thigh circumference: 57 -62 cm Material - Clasp: aluminum Dimension - Weight: 300 g Features - Special features: Fixation loop for rope/chalk bag - Number of gear loops: 4 - Number of belay loops/rings: 1 Safety - Test mark: EN 12277 Main information - Type: waist belt - Application: sport climbing Miscellaneous - Buckle type: DoubleBack HD buckle Details - Details: - Size (S): 280 g - Size (M): 300 g - Size (L): 320 g - Size (XL): 340 g.
