The Btoop 17-inch backpack utilizes a synthetic polyester velvet shell, providing a unique soft-touch texture that reduces potential skin irritation on bare shoulders. Because the material is a "pile" fabric, it is susceptible to "balding" at high-wear contact points like the base or shoulder areas. At approximately 0.5kg unladen, it is exceptionally light, making it a comfortable choice for light-duty transit.
Features include a dedicated sleeve for larger laptops, though the 5mm foam provides basic scratch protection rather than high-impact shielding. It is important to note that the velvet material acts as a sponge in wet weather; the bag is best used in dry environments or with an external waterproof cover. The structural limits are best respected by avoiding heavy gaming laptops or dense stacks of textbooks, as the velvet material relies on the internal 210D liner for its primary strength.
The zinc alloy zippers provide a smooth glide, provided the velvet pile is kept clear of the zipper teeth to prevent jamming. Without a sternum strap, weight distribution is most comfortable when the bag is not filled to its maximum 17-inch capacity.
If you need a bag that handles moisture better, the Lxygd Oxford fabric model might be a suitable alternative. You can view more large-capacity student bags in our cute backpacks collection.
