If you've been into ultralight backpacking for a while and have your gear finely tuned, you can handle even long-distance trails with it. The backpack is made from durable and waterproof Ecopak™ EPL Ultra 200 material. Ultralight frameless backpack made of waterproof Ultra 200 material. ## **Biggie Pack** The Biggie Pack offers you a **simple, proven design**, **7 spacious external pockets**, **waterproof material**, loops for attaching bungee cords, load-lifter straps, and a range of other features. The Biggie Pack offers a bit **more features** than a similar backpack [Elementum](/p/liteway-elementum-pack-50-l-2024). We will focus on the individual differences below in the features section. The backpack is available **in two sizes**: - **S/M** – 47 cm (mostly for individuals up to 175 cm tall) - **M/L** – 53 cm (usually for individuals taller than 175 cm) The length indicated for sizes is the distance from the top side of the shoulder straps to the bottom side of the backpack. ## Frameless construction The fact that the back of the backpack is not reinforced with a solid frame is both an advantage and a disadvantage. The main advantage is the **weight savings** on a part of the backpack that is not completely necessary. However, one must **pay more attention when packing things** into the backpack to prevent sharp objects from digging into their back. If you pack the backpack well, it is **really comfortable**. With a little practice, it will become easy for you, and you will perceive the lack of a frame as a **great positive**. Thanks to the frameless construction and minimalist design, the weight of the backpack has reached an incredible **520 grams**. We have found it effective to place a folded inflatable sleeping pad in a rectangle against the back of the backpack, [seat pad](/p/gramino-ultralight-sit-pad) or thin [EVA foam sleeping pad](/p/eva-foam-pad-3-mm). The second option for ensuring comfortable back support is to attach a seat pad or a folded foam sleeping pad **externally to the backpack**, using elastic cords that you can secure to the loops on the sides of the backpack. This way, you create **external padding** and will always have the seat pad at hand. The manufacturer states the backpack's load capacity is 12 kg. For maximum comfort, we would recommend keeping the **weight around 10 kg**. For this reason, the backpack is more suitable for more experienced hikers with well-tuned ultralight gear list. ## Features **Minimalist design** – the backpack has one main compartment with roll-top closure and a cross strap for additional compression or gear attachment. This allows you to easily adjust the height of the backpack based on its fill. **Wide shoulder straps** – especially with a frameless backpack, you will appreciate the wide, comfortable, and pleasantly padded shoulder straps. The padding is covered with a stretchy fabric that does not damage membrane clothing. **Side pockets** – the pockets on the sides are made of the same material as the body of the backpack and can easily hold a 2-liter bottle. They have an elastic rim at the top, so the contents do not fall out. At the bottom of the pockets, you will find a drainage hole to prevent water from collecting there during rain. **Sturdy kangaroo pocket** – on the front of the backpack, there is a spacious pocket made of durable ULTRA material. It is ideal for a waterproof jacket, toilet trowel, tent stakes, and similar gear. Additionally, the elastic drawstrings on the outside of this pocket provide another option for attaching lightweight gear/clothing. You can easily remove the cords and leave it at home or attach it elsewhere. **Attachment of the foam sleeping pad** – on the bottom side, the backpack has 2 paracords with a Lineloc tightening component prepared. You can easily attach a foam sleeping pad or other gear. **Comfortable hip belt with pockets** – spacious pockets on the hip belt measuring 18 cm can hold even larger smartphones. The zippers on these pockets are waterproof. In the right pocket, there is also a clip for attaching keys. **Mesh pockets on the shoulder straps** – on both shoulder straps, you will find a spacious pocket made of durable mesh fabric. These pockets are perfect for a small smartphone, sunglasses, snacks, tissues, and other small items you want to have within easy reach. **Side drawcords** – for attaching equipment to the sides, such as trekking poles, foam sleeping pads, etc., the drawcords with Lineloc can be useful. **Compatibility with hydration bladders** – inside the backpack, there is a loop for hanging the hydration bladder, and between the shoulder straps, you will find a hole for the drinking tube. **Adjustable chest strap** – you can slide the chest strap up and down, or you can remove it and leave it at home if needed. Biggie Pack differs from a similar backpack [Liteway Elementum](/p/liteway-elementum-pack-50-l-2024) with these features: - The front pocket is made of the same material as the backpack, namely **ULTRA instead of stretchy material**. - The backpack has **load-lifter straps**. - The backpack has a roll-top closure that can be **fastened to the sides** (these straps can be removed). - The pockets on the shoulder straps are made of **durable mesh**. - Inside the backpack, there are **2 straps for attaching a sleeping pad** to create the structure of the backpack. ## Technical parameters - Total weight – 440 g (520 g without all elastic cords and drawstrings) - Total volume – 45 l - Inner volume – 33 l - Volume of front stretch pocket – 5 l - Volume of side pockets – 2 x 2 l - Volume of shoulder straps pockets – 2 x 0,5 l - Volume of hip belt pockets – 2 x 1 l - Load capacity – up to 12 kg ## Materials The backpack is constructed from [**Ecopak™ EPL Ultra 200**](https://www.challenge-outdoor.com/ultra-collection) material. Stretch pockets are made of durable nylon, zippers from YKK, and buckles from Woojin Plastic. **Ecopak™ EPL Ultra 200** is a new line of waterproof fabrics for backpacks made of 67% woven UHMWPE (Ultra-high-molecular-weight polyethylene – unbranded dyneema fiber) and 33% recycled polyester blend Repreve. This layer is then laminated to a thin 0,5 mil RUV recycled film. **It is one of the strongest laminated materials for lightweight backpacks currently available on the market.** UHMWPE has a remarkable strength-to-weight ratio, making it **the strongest fiber in the world**. The fibers are 15x stronger than high-quality steel, lightweight, abrasion-resistant, waterproof, and resistant to UV radiation and chemicals. The main material 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 fully waterproof. In addition to its great properties, this fabric stands out for its **low environmental impact and high content of recycled materials**. The patented backing made from recycled Challenge RUV film is 100% recycled and 97% UV resistant. Every meter of ECOPAK™ fabric saves more than 0,5 kg of CO2 compared to nylon fabric. ECOPAK™ contains no harmful TPU, PVC, DWR, or other coatings. The CO2 emissions in the production of recycled polyester Repreve are 50% lower than those of nylon and comparable to organic cotton. **Material properties**: weight – 119 g/m²; waterproofness – 200+ psi (13,8+ bar); abrasion resistance ASTM 3884 – 4 400 cycles; fabric tear strength ASTM D2261 – 470 N / 47 kg (warp), 600 N / 60 kg (fill) ## Specs - Color: White, Black - Backpack size: S/M, M/L - Seam-sealed: No - Waterproof material: Yes - Backpack frame: Frameless - Backpack padding: No - Maximum load capacity: 12 kg - Sex: unisex - Material: Ecopak EPL Ultra 200, Woojin Plastic, YKK zipper, 3D AirMesh - Material composition: Polyester, Nylon, Ultra High Molecular Weight Polyethylene (UHMWPE) - Volume: 45 l - External volume: 12 l - Internal volume: 33 l - Weight: 520 g - Woocommerce product id: 80795 - Brand: Liteway ## Variants - Liteway Biggie Pack Ultra 45L - Small medium, White · SKU PBUSMW · €361.30 · In stock · White, S/M - Liteway Biggie Pack Ultra 45L - Medium large, Black · SKU PBUMLB · €361.30 · In stock · Black, M/L - Liteway Biggie Pack Ultra 45L - Medium large, White · SKU PBUMLW · €361.30 · In stock · White, M/L - Liteway Biggie Pack Ultra 45L - Small-medium, Black · SKU PBUSMB · €361.30 · In stock · Black, S/M ## Related - [Hyperlite Mountain Gear Unbound 40](/p/hyperlite-mountain-gear-unbound-40.md) - [Hyberg PAKKID](/p/hyberg-pakkid-dcf.md) - [Hyperlite Mountain Gear Windrider 55](/p/hyperlite-mountain-gear-windrider-55l.md) - [Liteway UL Wallet DCF](/p/liteway-ul-wallet-dcf.md) - [Liteway Choonie Apex](/p/liteway-choonie-apex.md) - [Liteway Elementum Pack Ultra 50 L (2024)](/p/liteway-elementum-pack-ultra-50-l-2024.md) - [Hyberg ATTILA ULTRA](/p/hyberg-attila-ultra.md) - [Liteway Fanny Pack](/p/liteway-fanny-pack.md) ## Shipping and returns - [Shipping and payment](/shipping-payment) - [Returns](/return-order) ## Images - ![Liteway Biggie Pack Ultra 45 L](https://media.gramino.com/medusa/4dd2f9f1e3394e6f6135eaad17c51192-01KWHVM7F2T5M2CBSHHRQJGQKH.jpg) - ![Liteway Biggie Pack Ultra 45 L](https://media.gramino.com/medusa/6b0a3b051c55285c1fb37eb0d2935912-01KWHVM7KX7QAMD9W9RWXAVPWJ.jpg) - ![Liteway Biggie Pack Ultra 45 L](https://media.gramino.com/medusa/6d55d2a15e851bd083f6869c05f2625a-01KWHVM7PV03GQ74N2FJZ0W4V1.jpg) - ![Liteway Biggie Pack Ultra 45 L](https://media.gramino.com/medusa/cf1d008bee5b0d800977719d4ebeee5f-01KWHVM7PFWEJV526TV0YSX3SB.jpg) - ![Liteway Biggie Pack Ultra 45 L](https://media.gramino.com/medusa/8404a20816fa233aa55f59ebd00c16df-01KWHVM7QMN5WDM8BQBQY2BN5K.jpg) - ![Liteway Biggie Pack Ultra 45 L](https://media.gramino.com/medusa/f781dc165563bcad818a38a8fd7a884b-01KWHVM7RJBSX65CKMJBFPKNGX.jpg) - ![Liteway Biggie Pack Ultra 45 L](https://media.gramino.com/medusa/cf6acacff4093e5f9d4b316df9432e58-01KWHVM7VJS1XC7TR5ZKKHRVQ3.jpg) - ![Liteway Biggie Pack Ultra 45 L](https://media.gramino.com/medusa/7699d0e30bb027f326b9d0e6e7454250-01KWHVM7T8XN6NHNDF22GQ9MSF.jpg) ## Identifiers - SKU: PBUSMW - Handle: liteway-biggie-pack-ultra-45-l - Brand: Liteway This product is also available as [HTML](/p/liteway-biggie-pack-ultra-45-l).
