Lightweight Large Capacity Soft Collapsible Cooler Bag and Leakproof Tote Backpack for Camping Hiking Picnic

• Our backpack uses high-density thick wear-resistant insulation material inside, and 800D high-grade fabric outside to make sure it is anti-leaking and keeps food hot/ cold for 10 hours. • The inter-layer uses thick 5mm pearl cotton to extend the heat preservation/cold time. The inside is made of PEVA insulation material, and the unique sealing design can prevent water leakage. • You can use it as a lunch backpack, but also an ideal lightweight equipment for hiking, camping, fishing, traveling, hunting, biking, overnight and other outdoor activities. • Wider and thicker shoulder straps can reduce stress and make it more comfortable. The thickened sponge on the back provides maximum comfort and support. • The adjustable shoulder straps are suitable for both men and women.
