Borosil Trek Black 500ml Bottle
The 500ml capacity provides a practical balance between portability and everyday hydration.
It is compact enough to carry to work, college, the gym or while travelling, while still holding a useful quantity of water, tea, coffee or other suitable non-carbonated beverages.
Borosil’s exact product specification lists the 500ml bottle at approximately 7.6 × 7.2 × 23 cm with a product weight of 330 g.
Its relatively narrow body is also designed to fit standard-size cup holders, making it convenient for car travel.

20 Hours Hot and 24 Hours Cold
One of the Trek series’ strongest features is its long temperature-retention capability.
Borosil officially rates the 500ml Black model to keep beverages hot for up to 20 hours and cold for up to 24 hours under recommended usage conditions.
For improved thermal performance, Borosil recommends pre-conditioning the bottle by filling it with hot water or ice for a few minutes before adding the final beverage.
Temperature retention can also improve when the bottle is filled appropriately rather than being left mostly empty.
Actual retention varies with starting beverage temperature, ambient conditions and how frequently the bottle is opened.
SS304 Stainless Steel Construction
Borosil’s official Hydra catalogue specifies rust-resistant SS304 stainless steel for the Trek series.
SS304 is widely used in reusable drinkware because it provides a durable, corrosion-resistant surface suitable for regular beverage contact.
The construction is also described as 100% food-grade stainless steel on Borosil’s current product page.
For best durability, the bottle should be cleaned regularly with mild detergent and thoroughly dried before storage.
Borosil specifically advises against placing the Trek bottle in a dishwasher.
Double-Wall Vacuum Insulation with Copper Coating
The Trek Black uses double-wall vacuum insulation with copper coating to reduce heat transfer between the beverage and the surrounding environment.
Vacuum insulation reduces conductive and convective heat transfer through the bottle wall, while the copper layer further supports thermal retention.
This construction also keeps the exterior comfortable to hold when hot beverages are inside and helps prevent condensation when the bottle contains cold drinks.
The result is a dry exterior that is more convenient inside backpacks, handbags and office bags.
Leak-Proof Screw-Top Lid
Borosil officially describes the Trek bottle as leak proof and confirms a screw-top lid.
A secure lid is especially important for a bottle intended to be carried inside backpacks and work bags.
The cap should always be tightened correctly before transport, and the sealing surfaces should be kept clean to maintain proper closure.
Borosil also sells replacement lids for the Trek range, although replacement spare parts are not covered under the bottle warranty.
Wide-Mouth Design
The Trek features a mouth wide enough for easy drinking, cleaning and adding ice cubes.
A wider opening can make the bottle easier to rinse than very narrow-necked flasks and can accommodate standard ice cubes for chilled drinks.
Borosil also describes the mouth design as supporting drip-free sipping.
When cleaning, mild detergent and a suitable bottle brush can be used as required.

Powder-Coated Black Finish
The Black Trek version uses a powder-coated exterior finish designed to maintain its appearance during normal daily handling.
The matte dark finish gives the bottle a clean, understated appearance suitable for office, gym and travel environments.
Although the coating is intended for durability, sharp objects and abrasive cleaning tools can still damage any painted or coated surface.
Cleaning the exterior with a soft damp cloth is therefore preferable.
Condensation-Free Exterior
The vacuum-insulated construction helps keep the outside surface sweat free with cold drinks.
Borosil specifically notes that the exterior remains condensation free, helping keep hands, desks and bags dry.
With hot liquids, the insulated body is also designed to remain comfortable to touch.
This makes the bottle useful for both chilled water and warm beverages during everyday travel.
Safe Everyday Drinkware Design
Borosil states that the plastic components used in the bottle are BPA and phthalate free and food grade.
The bottle is intended for normal hot and cold beverages but Borosil advises against storing carbonated and alcoholic drinks.
When the bottle is not in use, leaving it uncovered can help minimise trapped odours.
The bottle should also not be placed in a dishwasher.
