EXPANDABLE & LARGE CAPACITY: This extra-large travel backpack with an expandable design gives you more packing room (Size: 17.32*12.2*6.7+1.57inch). Unzip it to get 40L of storage, easily fitting packing cubes, makeup bags, outfits, camera gear, and more. It’s ideal for men, women, weekend travelers, or anyone taking an occasional vacation, and it meets airline personal-item requirements too.
LOTS OF POCKETS & LAPTOP COMPARTMENT: The Sinaliy travel backpack for men and women has a spacious laptop compartment with thick cushioning to protect your laptop well. It offers ample storage with multiple hidden pockets, plus two toiletry bags for your hair and bath products.
WITH LUGGAGE BELT & ANTI-THEFT POCKET: The luggage belt on the back lets business travelers slide this travel backpack right onto their suitcase for easier carrying. A hidden anti-theft pocket on the lower back keeps your valuables like wallet, passport, and ID card safe from thieves when you’re traveling or waiting in line.
-LONG USING LIFE: Made of lightweight, water-resistant polyester and anti-scratch material, this Sinaliy men’s travel backpack keeps your stuff dry in light rain, while still being breathable and good at heat dissipation. Sturdy zippers and solid stitching mean this personal item backpack won’t wear out on your trips, making sure your weekend getaways are hassle-free.
– CONVERTIBLE DESIGN: The carry-on backpack has hideaway padded shoulder straps that can be stored in the zippered back panel, turning this personal item bag from a carry-on duffel into a briefcase style. Use the side handle for a more flexible carrying experience.
-PERFECT PRESENT: The Sinaliy 40L travel laptop backpack is a top gift pick for Father’s Day, birthdays, Valentine’s Day, Thanksgiving, Christmas, and New Year. It’s great for gifting to your father, boyfriend, husband, son, friends, and more—perfect for anyone who travels, commutes, does business, hikes, or camps.
