Windhike Naturehike Rock 40L/60L+5L Internal Frame Hiking Backpack Ultralight Daypack with Rain Cover

Overview

Meet the Windhike Naturehike Rock series, a set of ultralight internal frame packs designed for day hikes, weekend treks, and light camping. Choose among 40+5L or 60+5L capacities, with an updated 60+5L version that balances roomy storage with a featherweight feel. Weighing roughly 2.33 lb for the 40+5L, 2.55 lb for the 60+5L, and 2.88 lb for the updated 60+5L, these packs aim to minimize fatigue while keeping essential gear within easy reach on trail days.

Materials and weather protection

The main shell uses rugged 420D nylon that resists abrasion and sheds light mist. It is water repellent, not fully waterproof, which is why a rain cover lives in the bottom pocket for sudden showers on the trail. The updated 60+5L version adds a polymer fabric with 6% high molecular weight polyethylene fibers, boosting abrasion resistance on rough routes and withstanding daily packs and straps.

Comfort and fit

The carry system emphasizes ergonomic design with a curved EVA back panel and double-layer EVA on the shoulder straps for comfort across longer carries. A three-dimensional internal frame maintains structure without bulk, while a two-way tension waistbelt helps customize the wrap as you move. A DIY wind rope at the top offers an adjustable touch for varying weather or gear setups.

Storage, pockets, and versatility

Storage is organized and accessible thanks to multiple pockets and a large back mesh pocket for quick items. On the outside, compression straps on the top and both sides help secure a sleeping bag, jacket, trekking poles, or a rolled mat. The layout supports easy access to snacks, maps, or a compact camera during breaks on the trail.

What you can expect on the trail

These packs suit a range of adventures from short day trips to light overnights. The ultra-light frame feels near invisible when you move, while the varied capacities let you tailor your load. Real-world setups might include a compact sleeping bag, a compact stove, water bottle, a light rain layer, and a few essentials tucked into the back mesh pocket for fast reach.
