Koolertron’s canvas cross-body bag is a compact bag ideal for carrying a number of essentials on a regular basis. It is lightweight, made from a durable, understated lined fabric with zipped pockets and an adjustable shoulder strap. It has a generous central pocket – big enough to fit a few items including a small water bottle – that also has a small internal zip pocket. The second pocket is a smaller zip pocket that comfortably fits a wallet and change purse. The third pocket is tall and slim with a popper fastening and fits both my Kindle and phone.

The zippers is the weakest point in the design, but although not top quality, mine has lasted 6+ weeks and haven’t shown any signs of wear. The cotton canvas is durable and the stitching is neat and tidy. The strap isn’t padded, but as it is wide and ajudstable on a bag that is small and light, it fits comfortable on the shoulder or cross-body.

It’s a budget choice for a surprisingly durable bag. It isn’t the high quality design of a top of the line brand, but it neither markets or prices itself as such. A cost-effective choice.

I have been looking for a regular daily bag for a while. A bag that is large enough to carry all my essentials – phone, wallet, keys, Kindle, small water bottle, essential medication, Epi-Pen, inhaler, tissue pack, hand sanitizer, sunglasses, pen, small note-book – without feeling overfull or become too heavy to carry. A bag that doesn’t have to be waterproof, but is thick enough to withstand a few raindrops on the walk to school.

A bag I can hand off to my husband without him giving me that look of horror as he starts humming “Alone at Home”* by Jonathan Coulton.

This is that bag. It’s a good quality bag at a low cost and it’ll last a while. Recommended for anyone also looking for a decent medium-sized bag that fits all the essentials without becoming uncomfortable to cart around everywhere.
