Mountainsmith Strapette Harness for Lumbar Packs – Convert to Daypack

Meet the Mountainsmith Strapette, a detachable shoulder harness that transforms a classic lumbar pack into a versatile daypack in moments. It’s designed to be feather-light and quick to fit, so you can switch between compact carry and a more expansive setup without slowing down your pace. The result is a flexible carry solution that travels with you—from first light hikes to late-night city strolls—without adding unnecessary bulk.

The Strapette uses adjustable foam shoulder straps and a configurable sternum strap to balance the weight across your torso. When you load your pack with essentials for a day trip or a longer adventure, the strap system helps keep the load centered and steady as you move, reducing shift and wobble as you walk, climb stairs, or weave through crowds. The result is a more natural, comfortable carry feel, so you can focus on your route, scenery, or itinerary rather than the tension in your shoulders.

Compatibility is straightforward. Strapette is designed to pair with Mountainsmith’s Day, Tour, and Travel Trunk packs in multiple sizes, including large, extra-large, and extra-extra-large options. Despite its versatility, the harness remains exceptionally lightweight, weighing about 0.3 ounces, so it blends with your kit rather than drawing attention to itself. This means you can adapt an existing setup for day use without sacrificing overall pack weight.
