Liteway says: 

Biggie Pack Ultra 45L – is an ultra-lightweight frameless backpack for long distance hikes.

The backpack has a simple design and an increased volume is 45 litres. Entrance to the main body compartment is on the roll top, it’s made for quick access and easy volume adjustment.

The unique design has a simple roll top construction which can be fast loading and easily adjusting the volume. There are a lot of additional pockets for quick access, convenient placement and easy packing of gear in it. 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. A feature of the backpack is the removable straps at the side of the rolltop, the central strap and the load-lifters straps can be customised backpack.

The backpack has frameless design. For the forming the frame of the BIGGIE PACK we recommend using a sleeping mat, and putting it along the back of the backpack. Unlike the Elementum, the Biggie Pack hasn’t got a front compartment made of elastic material, but it has a large front pocket made of Ultra™ 200.

There are some holes for water drainage in the bottom part of Pack.

The lacing system of the front pocket can be used for drying clothes and gear during hikes or for additional fastening of equipment on the trail.

The backpack has 7 pockets: a central large front pocket, two voluminous pockets on the backpack belt, two side pockets and two updated pockets on the straps.

New mesh pockets on the shoulders straps: increased volume, now the pocket is fixed with a tightening system, and the pocket can also be closed/opened with one hand. The backpack has a removable load-lifters system on the shoulder straps and in the upper part of the backpack. Lacing is provided for attaching additional gear on the sides and in the lower part of the backpack.

The weight of the backpack is approximately 540g, and 440g without removable straps, shock-cords and cords.

Our Verdict

The Liteway Biggie Pack 45L, with Ultra™ 200 fabric, is even lighter than the “Biggie Pack” counterpart, shedding an impressive 126g. Weighing 526g (S/M), it’s an exceptional option for long-distance hikes and multiday adventures, offering a full 45-litre capacity that can be adjusted with its roll-top design. While the pack’s minimalist design is a standout feature, it’s still packed with thoughtful details like seven pockets for gear organisation, water drainage holes, and removable straps for a customised fit.

The frameless design allows you to use a sleeping mat as back support. Internal straps help secure the mat in place, but there are also external loops on the pack for attaching a pad (you need to attach some cord), which I’d prefer. Using a textured sit pad externally would improve ventilation, helping to keep your back cooler during long hikes.

The Ultra™ 200 fabric is incredibly durable despite its low weight, and the large front pocket is ideal for stashing wet weather gear, with the lacing system keeping everything snug. The shoulder and hip belt pockets are convenient for easy access to essentials on the move, and the mesh pockets on the shoulder straps are spacious enough for a phone or water bottle, with a tightening system for added security.

One minor improvement would be the compression straps on the sides. Currently elasticated, I prefer straps with no give, but this is a simple adjustment for those who prefer a more rigid fit.

While the pack’s seams aren’t sealed, meaning it’s not fully waterproof, the Ultra™ 200 fabric is highly weather-resistant. It won’t absorb water, so the pack remains lightweight even in wet conditions.

The lightweight construction, functionality, and customisable features make this pack ideal for ultralight hikers. I might have found a new favourite backpack for multiday trips.
