Weighing just 102g and made from durable TPU with RF welded seams, it compresses to pocket size when empty and features a high flow nozzle with a dust cover. Compatible with 42mm backcountry filters, it’s designed for professional adventurers who demand lightweight, space-saving, and reliable hydration on every trek. ## Description Flexible bottles get an upgrade. The Flux is shaped like a hard bottle, compresses like a softflask, and cuts weight by 50%. Topped with a dust cover and twist-drink nozzle for grab-and-go hydration, plus a bail handle to keep hydration secure in your hand or on your pack. The Flux stands upright like a hard bottle but when you finish your drink, this bottle packs down to pocket size. Weights and Dims Flux 1L Capacity: 1L / 32 fl oz Weight: 102 g / 3.6 oz Dimensions: 230 mm x 90 mm / 9.1 in x 3.5 in Review: Much improved over the previous generation, love that it stands on its own - I've tried a few soft bottles because there's a lot of appeal for camping and traveling - lightweight and doesn't take a lot of space, and sometimes I don't want to deal a hydration bladder. They've all had issues - nalgene's would fall over due to the large wide mouth cap, platypus's were impossible to dry, and so on. Found an older model of the hydrapak flux that I loved for camping and traveling - super easy to pack, came in at least 32 oz, stood up on it's own, and was easier to clean and dry. Didn't super love the twist cap as it didn't release air so it would eventually flop over as you drank, and the mouthpiece was exposed. After the wife made me carry her double walled bottle during skiing, I bought her bottle, and I feel it's been improved in every way. It's wider so there's a more stable base, they added a flip cap, and now when you untwist, it lets air escape so the bottle will expand back to it's normal shape. They added clear plastic on the top so it's easier to see how much liquid is left, and the cap prevents leakage while still in the open twisted position. The loop is longer which makes it easier to roll up as in the pictures, but it's still kind of a pain, so I rarely do it. I'm undecided whether to just steal my wife's bottle, or buy a second one for myself. I still use hard bottles for sizes about 32 oz as I'm unsure of the sturdiness of the larger sizes, but this has become my go to whenever I want to take some water out of the house. Review: The best collapsible water bottle I've tried - I've never written an desertcart review but felt compelled to do so after buying many different types of collapsible water bottles at once. This is my favorite. It has some structure but also collapses. It's pleasant and fun to drink out of. It does have a bit of a rubbery/plastic-y taste that might bother some people -- personally, I don't mind it at all. Durable materials. Recommended. ## Features - LIGHTWEIGHT & COMPRESSIBLE: 50% lighter than a hard bottle and compresses down to pocket size when empty. - HIGH FLOW NOZZLE: High flow drink nozzle includes protective dust cover and can be quickly opened and closed with one hand. - FILTER COMPATIBLE: Compatible with 42mm threaded backcountry water filters including the HydraPak 42mm Filter Cap. - FITS IN PACK POCKETS: Designed to fit in pack pockets when full and to roll up when empty for space saving storage. - ULTRA DURABLE: Made of dual-layer film laminate construction, with abrasion resistant TPU & RF welded seams for superior durability and elasticity. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BRBPR3MX | | Additional Features | Collapsable, Filter Compatible, Lightweight | | Age Range Description | Adult | | Best Sellers Rank | #4,065 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #227 in Water Bottles | | Bottle Type | Collapsible Water Bottle | | Brand | HydraPak | | Brand Name | HydraPak | | Capacity | 2 pounds | | Color | Mammoth Grey | | Container Type | Flexible Bottle | | Customer Reviews | 4.2 out of 5 stars 1,782 Reviews | | Global Trade Identification Number | 00834456003038 | | Included Components | 1 Collapsible Water Bottle | | Item Dimensions W x H | 4.75"W x 9.1"H | | Item Type Name | FLUX 1L | | Item Weight | 102 g | | Manufacture Year | 2023 | | Manufacturer | Hydrapak | | Manufacturer Part Number | HYGF420MN | | Manufacturer Warranty Description | Lifetime Warranty | | Material | TPU , POM | | Material Type | TPU, POM | | Material Type Free | Bisphenol A (BPA) Free | | Model Name | FLUX 1L | | Model Number | GF420M | | Number of Items | 1 | | Product Care Instructions | Dishwasher Safe | | Recommended Uses For Product | Backpacking | | Reusability | Reusable | | Shape | Rectangular | | Special Feature | Collapsable, Filter Compatible, Lightweight | | Sport Type | Camping & Hiking, Climbing, Outdoor Lifestyle, Training, Yoga | | Style Name | 1L/32oz | | Theme | Outdoor Activities | | UPC | 834456003038 | | Unit Count | 1 Count | ## Product Details - **Bottle Type:** Collapsible Water Bottle - **Brand:** HydraPak - **Capacity:** 2 pounds - **Color:** Mammoth Grey - **Material:** TPU, POM ## Images ![Flux Collapsible Backpacking Water Bottle (750ml, 1L, 1.5L) - Image 1](https://m.media-amazon.com/images/I/71eNMvCrEoL.jpg) ## Available Options This product comes in different **Color, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Much improved over the previous generation, love that it stands on its own *by F***1 on May 2, 2024* I've tried a few soft bottles because there's a lot of appeal for camping and traveling - lightweight and doesn't take a lot of space, and sometimes I don't want to deal a hydration bladder.

I just used them on a 3 day backpack trip and really liked how the 46mm mouth adapts to my BeFree filter. This system made water management much easier. Two minor issues to be aware of… rinse multiple times before use to reduce nasty plastic taste, which is not a concern with Nalgene bottles. Secondly, because they are collapsible, they have a tendency to tip over especially when empty and your hands are being used to fill them from a water filter. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/524857281-flux-collapsible-backpacking-water-bottle-750ml-1l-1-5l](https://www.desertcart.tn/products/524857281-flux-collapsible-backpacking-water-bottle-750ml-1l-1-5l) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-10*
