Great bag! Lots of space
I loved this bag as it has great storage space and some really practical compartments. It is also great to carry as it has a strap system to keep it in place. It is great quality too and is a nice colour (navy blue). It was also a great price. I would definitely buy it again.

Nice.
Comes with 3 compartments and a chest clip so you don't have to hold on to the draw strings just needs to be a little bigger and it's perfect.

Tough, roomy, and clean-looking—solid sackpack for gym gear, van stash, or shift-ready carry.
Built for daily use—drawstring closure’s smooth and secure, and the chest clip adds stability when walking or cycling. Material’s water-resistant and easy to wipe down, so it handles site dust, gym sweat, or light rain without fuss. Fits trainers, towel, bottle, and extras without bulking out. Logo’s bold but clean, and the graphite/black/white combo keeps it sharp without looking flashy. Ideal for gym runs, van stash, or keeping a spare kit ready for shifts. Folds flat when empty—easy to store in a drawer, locker, or glove box. Stitching’s solid, and the straps don’t dig in even when loaded. Minor gripe: no internal pockets—just one main compartment. 👍 Pros ✅ Lightweight and durable—built for daily use ✅ Chest clip—adds stability on the move ✅ Water-resistant fabric—easy to clean ✅ Compact design—folds flat when empty ✅ Fits essentials—trainers, towel, bottle, etc. 👎 Cons ❌ No internal pockets—just one main compartment ❌ No zip closure—drawstring only ❌ Limited padding—not ideal for heavy loads

Strong and sturdy
Great bag, used for my daughter for pe at school. Some of the other brands have fell apart after a few days weeks but this one Is doing great 6 ish months in. Fits loads in and straps are comfortable to wear

Quality Bag
Excellent build quality and materials used. Loads of room in the main compartment and the 2 additional pockets are very useful. Very lightweight and functional.

Cords came out in a matter of days
It's very well priced but it's neither a simple "pe bag" or a rucksack, it's too bulky to fold away but not strong enough to be an everyday bag...
