SYTRAH Water Bottle Bag Crossbody Insulated Shoulder Purse Black — Holds 591 ml (40 oz)–1.18 L Tumblers, RFID Protection

The SYTRAH Water Bottle Bag Crossbody is a compact insulated shoulder purse that securely carries 20–40 oz tumblers while organizing essentials like phone, cards and keys.

Designed for people who want hands-free hydration and tidy storage, this black SYTRAH crossbody combines thermal insulation, RFID protection and multiple pockets in a lightweight sling. Its slim profile fits popular bottles up to 4.2" diameter and 11.5" height while offering dedicated spaces for a phone, cards and small accessories. The outer shell resists water and scuffs, and an adjustable wide strap keeps wear comfortable during long days on the move.

How does it keep drinks hot or cold?

The interior uses a high-density foam layer plus reflective aluminum lining to slow heat transfer, helping beverages maintain temperature longer than an uninsulated carrier. The drawstring and double-zipper closure also reduce air exchange for better thermal performance.

• Insulated liner: foam plus aluminum reflective layer
• Secure elastic drawstring and double zipper seal
• Wipes clean and dries quickly after use

Will my water bottle and phone both fit comfortably?

This bag is sized to hold most popular tumblers—20, 24, 32 and 40 oz—while leaving room for a phone in the front zip pocket. The phone compartment accepts smartphones up to 6.9" (including Pro Max models with a case), and side pockets store small items like earbuds or lip balm.

• Internal space fits bottles up to 4.2" diameter and 11.5" height
• Front zip pocket fits phones up to 6.9" with case
• Two side pockets for accessories and a built-in key hook

How does the bag protect my cards and personal items?

SYTRAH built RFID-blocking slots into the interior so you can carry a few essential cards without exposing them to unauthorized scans. The bag also includes multiple zipped compartments and a key hook to keep small valuables organized and easy to reach.

• Five RFID-blocking card slots for contactless card security
• Two front zipper pockets and two side pockets for organization
• Internal key hook prevents misplacing keys

Is the strap comfortable for daily use and travel?

The wide shoulder strap is adjustable and removable, extending from 28" to 52" so you can wear it crossbody or over a shoulder. The broader strap reduces pressure during long walks or commutes, making it suitable for all-day carry.

• Adjustable & removable wide strap (28–52 inches)
• Lightweight overall weight at about 0.6 lbs for all-day wear
• Durable nylon outer shell resists splashes and abrasions

Who this fits: the SYTRAH insulated water bottle crossbody is ideal for commuters, hikers, gym-goers, parents and travelers who want an organized, hands-free way to carry a tumbler and daily essentials. It’s particularly useful for anyone using popular bottle brands like Hydro Flask, YETI, Stanley or Simple Modern and for people who prefer a single compact bag with temperature retention and RFID protection. The black finish keeps the look versatile for casual outings, outdoor adventures and everyday errands, and it also makes a practical gift for active friends or family.
