"One of the best backpacks I’ve ever used!"
The shoulder pouches were very handy, the straps were comfortable, and the double sternum strap was a really nice touch.
Backpack carried weight very well. I had extra weight because of camera gear, and it still felt very good. 100% recommend.
Designed as a modular system that works together
Individual by design. Exceptional together.
Every piece of the XT Series is designed with one goal - to keep you moving. Four technically advanced layers, each with a precise role: a breathable base, an adaptive mid, insulated warmth, and full weather protection. Worn together, they form Kathmandu's most complete hiking system. Worn individually, each piece still earns its place.
LayerOne - Base Layers - Coming soon
A breathable base layer, LayerOne sits close to your skin to wick sweat, regulate warmth, and move with you.
LayerTwo - Octa Hybrid Fleece
Our versatile mid layer, sitting perfectly between base layers and shell. Soft, breathable, and built to hold warmth without holding you back.
HeatLock - Down Jacket
Warm without the bulk. HeatLock traps heat while staying breathable. Reliable from crisp mornings to cool evenings.
HydroProof - Rainwear
Fully waterproof, windproof, and seam-sealed to shield you from the storm. Breathable tech means you won't over heat when the pace picks up.
2025 ISPO Award Winner
A 2025 ISPO Award winner, the ISPO jury described the pack as “exceptionally versatile thanks to its modular design and ultralight construction,” praising Kathmandu’s use of high-tech materials and emphasis on durability without adding weight.
"With the XT Series Pack, we set out to create something that truly reflects the way people move through the outdoors today – light but tough enough to go the distance and handle whatever the trail throws at you,” says Kathmandu Head of Product Management Jaime Toothman.
