Liteway says: 

Ultra light backpack GRAMLESS PACK 35L.

The main material (fabric) of the backpack is 100% waterproof, but please, note that the seams of the backpack are not sealed. This means that the backpack is not waterproof.

The unique design has simple roll top construction which can be fast loading and easily adjusted. There are a lot of additional pockets for quick access, convenient placement and easy packing of gear. The backpack helps to improve your speed, efficiency, increase hiking distance on the trail. Ideally for those who want to save every gram in their gear.

Our Verdict

The Liteway Gramless Pack 35L is a fantastic option for ultralight hikers who want to minimise pack weight without sacrificing functionality. Weighing just 404g for the small/medium size, this frameless backpack offers a solid 35-litre capacity, making it ideal for shorter multiday trips or minimalist adventures. The roll-top design allows for quick access and easy adjustment of the pack’s volume, while five additional pockets—including large side pockets—make gear organisation simple and efficient.

One standout feature is the durable X-Pac fabric, which is 100% waterproof. However, the seams are not sealed, meaning the pack isn’t fully waterproof. However, it won’t absorb water, so the pack remains lightweight even in wet conditions. The pack’s design also includes loops for securing a sleeping pad along the back, providing structure in an otherwise frameless pack. 

The Gramless Pack’s lightweight design, minimalistic features, and ability to carry up to 12kg make it perfect for ultralight hikers who value speed and efficiency. It’s a reliable, no-frills pack for those who want to save every gram on the trail.
