These unique knapsacks are individually handcrafted and come in a variety of colors and style combinations. Each Catamaran backpack is unisex, providing both a functional and [minimalist solution to everyday storage](https://www.trendhunter.com/trends/nanobag-daypack). This collection does a tremendous job of blending industrialism and fashion into one unified piece. The bag is inspired by a traditional envelope and is opened and closed using a recognizable pointed flap. The bag even folds like an envelope when there are only a few things in it, as well as when it is not in use. The Catamaran backpack is also versatile, allowing for [different ways to carry it](https://www.trendhunter.com/trends/ultix-outdoors-superpack). The bag can be used like a traditional knapsack, or [transformed into a purse](https://www.trendhunter.com/trends/mercurius). ## Trend Insights (Trend Hunter) - Score: 3.1/10 - Popularity: 58% | Activity: 27% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Gen Z, Millennial - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Art & Design](https://www.trendhunter.com/artdesign) > [Design](https://www.trendhunter.com/design) ## Key Themes ### What Makes This Trend Stand Out - **Envelope-inspired Designs:** Incorporate the iconic pointed flap of an envelope into various products to add a recognizable and functional element. - **Functional Minimalism:** Create products that offer practicality and simplicity, without sacrificing style or aesthetics. - **Transformable Products:** Develop versatile products that can be used in different ways, such as transforming a backpack into a purse. ### Sectors Adopting This - **Fashion:** Introduce envelope-inspired designs into apparel and accessories, such as using the pointed flap as a closure feature or incorporating envelope-like folding techniques. - **Stationery:** Implement the envelope design into stationery products, such as notebooks or envelopes themselves, adding a unique and recognizable feature. - **Consumer Goods:** Apply the envelope-inspired design into various consumer goods, such as storage containers or tech cases, for both functionality and style purposes. ## Related on Trend Hunter - [Multimodal Waterproof Backpacks](https://www.trendhunter.com/trends/multimodal-waterproof-backpacks.md) - [Sophisticatedly Playful Backpack Designs](https://www.trendhunter.com/trends/fjallraven-kanken-koncept.md) - [Ultra-Compact Packable Backpacks](https://www.trendhunter.com/trends/nanobag-1.md) - [Earbud-Inspired Backpack Designs](https://www.trendhunter.com/trends/airpack-backpack.md) - [Minimalist Accordion-Style Backpacks](https://www.trendhunter.com/trends/lundi-rubens-backpack.md) - [Zipper-Free Convertible Backpacks](https://www.trendhunter.com/trends/convertible-backpacks.md) - [Ultra-Compact Backpack Designs](https://www.trendhunter.com/trends/nanobag-daypack.md) - [Chic Weekend Jaunt Backpacks](https://www.trendhunter.com/trends/carl-friedrik-72hour-backpack.md) - [Organization-Forward Backpack Drops](https://www.trendhunter.com/trends/matrix-backpack.md)
