Performance
Despite its ultralight 11.5 g weight, the bottle handles travel rigour well. Filling, squeezing, and hanging in hostel showers shows no leaks; the flip-cap sits secure; and the fabric acts like a mini stress ball when squeezed (). Its form factor shrinks as contents do, saving space. Some edge fraying at welds appears after months [oai_citation:0‡Pack Hacker](https://packhacker.com/travel-gear/matador/flatpak-toiletry-bottle/?utm_source=chatgpt.com) — cap hinge could be sturdier — but function stays sound.
