YETI Rambler 18oz Straw Bottle in Navy - Our FAQs

1. Is the bottle fully leakproof?
   When the straw cap is closed, the bottle is leakproof. However, it is not recommended for loose packing inside bags as jostling may cause the cap to open.

Cost Per Wear - A Rough Guide

YETI products are synonymous with extreme durability and are designed to outlast several cheaper alternatives. Based on 2026 standards for premium stainless steel drinkware, we estimate a lifetime of at least 1,500 uses for a well-maintained bottle.

• Retail Price: £30.00
• Estimated Uses: 1500
• Cost Per Use: £0.02

Our CPW calculation is purely speculative and based on a loose idea of expected use over its lifetime. If you really give the item some prolonged, hard, regular wear then the numbers are likely to change.
