Best for: Lifters who want a compact backpack with a laptop sleeve, and anyone who trains before or after work.
Our recommendation
Buy the Under Armour Hustle 5.0 if you want the bigger, plainer backpack: 29 litres, a padded 15 inch laptop sleeve, and a water-repellent finish for the commute. Buy the Gymreapers Gravestone 21L if you want a compact, tougher pack built for the gym floor, with a water-resistant shell and a smaller footprint. Both cover training and work, so the choice is size and plainness against compactness and toughness.
Capacity: 29 litres against 21 litres
The Hustle holds a full session plus a laptop, with room to spare. The Gravestone holds a session and a laptop, but the load has to be chosen carefully, since a belt, straps, and shoes fill it fast. For a light session the Gravestone is the neater bag, and for a full session the Hustle is the safer pick.
Weather and toughness
Both are water-resistant, but the Gravestone shell is the tougher of the two, with a structured shape that holds up on the gym floor. The Hustle finish sheds rain on the walk, and the base handles daily use. Neither is waterproof, so neither should stand in a puddle.
Looks and branding
The Hustle is plain black with a silver logo, which suits the office as well as the gym. The Gravestone carries a skull logo and a tougher look, which suits the gym floor and will not suit every office. Buyers who want one bag for both should weigh the branding as much as the capacity.

Strengths and limitations
Under Armour Hustle 5.0 Backpack
Strengths
- The two-strap carry spreads the load across both shoulders, which beats any duffel on a long walk or a bike ride.
- The padded laptop sleeve takes a 15 inch laptop, so the same bag covers the gym and the office.
- The water-repellent finish and the tough base keep the bag dry and clean through daily use.
Limitations
- There is no separate ventilated shoe compartment, so trainers go in the main compartment with everything else.
- At 29 litres it holds a session, but not a weekend of kit, and bulky items have to be left out.
- The front organisation pocket is shallow, and a thick wallet or a large phone fills it fast.
Gymreapers Gravestone 21L Backpack Travel Gym Bag
Strengths
- The water-resistant shell and the structured shape hold up on the gym floor and in the rain on the way home.
- The laptop sleeve and the organised pockets mean the same bag covers training and the office without a second bag.
- At 21 litres it is compact enough to sit on a bench or in a small locker, and it never feels oversized.
Limitations
- At 21 litres it holds a session but not a weekend, and a belt, straps, and shoes fill it fast.
- There is no separate shoe compartment, so trainers share the main space with clean clothes.
- The skull branding is loud, and it will not suit buyers who want a plain bag.

Questions, answered
Do either have a shoe compartment?
No. Neither backpack has a separate shoe compartment, which is the main trade-off against the duffels. Trainers go in the main compartment, so a shoe bag inside the pack helps, and a plastic bag works in a pinch.
Which one is better for cycling to the gym?
The Hustle, because the 29 litre size and the two-strap carry spread the load, and the water-repellent finish handles rain on the ride. The Gravestone is compact and tough, but the smaller size means the load has to be chosen carefully, and a full session may not fit.
Which one lasts longer?
The Gravestone, on balance, because the structured water-resistant shell is built for the gym floor. The Hustle lasts well for commuting, but the lighter finish will show wear sooner under heavy gym use. Both last years when used for their intended job and stored dry.
