What Our Gearhead® Experts Are Saying:

"The Aircontact Ultra 45+5 SL is my go-to for multi-day backpacking trips where every ounce matters. It’s incredibly lightweight, but the Aircontact back system still provides great ventilation and comfort, even under heavier loads. The modular design lets me customize my carry—whether I need the extra 5L of space or want to strip it down for a minimalist setup. The ergonomic hip fins and adjustable torso length ensure a secure fit, making long days on the trail feel effortless."

Designed for serious trekkers who demand ultralight performance without sacrificing comfort, the Aircontact Ultra 45+5 SL is built to carry essential gear with ease. Its innovative Aircontact back system enhances ventilation, reducing heat buildup on strenuous ascents, while the ergonomic hip fins ensure a snug fit that effectively distributes weight for all-day comfort.

This pack’s modular design allows for versatility—remove the lid and compression straps when you need to cut weight, or expand the roll-top closure for an extra 5L of storage.
