Built for people who want a bottle that can handle rough handling, not just a desk, the Borosil Trek 500ml Black vacuum flask brings Borosil's outdoor-ready Trek design into a compact 500 ml size. The double-wall vacuum insulated steel body is engineered with the same rugged philosophy as the larger Trek 700, keeping drinks noticeably hot or cold for hours on a trail, a commute, or a long day outdoors. The matte black finish keeps scuffs from showing and gives it a sturdy, no-nonsense look.
The Trek 500 is built from BPA-free stainless steel with a secure, leak-resistant cap that holds up to being tossed into a backpack or bike pannier without worry. Its slightly smaller size compared to the Trek 700 makes it a good fit for anyone who wants the same tough build in a lighter, more compact bottle for daily carry.

The Trek 500 shares its double-wall vacuum insulated steel construction with the rest of Borosil's Trek range, designed to handle outdoor use, bumps and drops better than a standard everyday bottle.
At 500 ml, it's a lighter, more portable option than the larger 700 ml Trek bottles, suited to shorter outings, gym sessions, or anyone who prefers a smaller bottle for daily carry.
The entire body is made from food-grade steel with no BPA, keeping every sip free of plastic taste even after repeated refills.
The cap is built to stay sealed through active movement — a hike, a cycle ride, or simply being carried in a backpack — so it can be packed without worrying about leaks.
The Trek 500's tough, matte-black look makes it a fitting corporate or farewell gift for colleagues and friends with an outdoor or fitness streak, since it's a bottle they'll genuinely use on treks, runs or gym trips rather than leave on a shelf.
It holds 500 ml, matching its name exactly, making it the more compact option in Borosil's Trek range alongside the larger 700 ml version.
