Australian bag maker Bellroy just released a major upgrade to a few of its best styles. The Premium Collection — made up of a backpack, a sling and a tote — features environmentally certified leather and contrast details. Each bag is available in two versatile colors, Black Sand and Desert, and is backed with the brand’s three-year warranty.

Each bag pairs hard-wearing woven nylon with leather tanned under gold-rated Leather Working Group environmental protocols. “We designed our Premium bags for those who take pleasure in fine aesthetic detail,” said Bellroy designer Rowan Dinning in a statement. “That bit of extra care makes all the difference. We even specially developed a leather for this that’s softer and more robust than our wallet leather, with extra body to hold its shape.”

Ideal for everyday use, the bags have capacities that range from 7 liters for the sling to 20 liters for the backpack. Both the tote and the backpack are designed to hold laptops or tablets and each bag has a range of functional details including water-resistant pockets, soft-lined sunglasses pouches and key clips. Starting at $159, these bags are well worth investing in and will serve you well for years to come.
