How the Undeniable 5.0 compares
Undeniable 5.0 MD vs the Undeniable Backpack Duffle
Both hold 58 liters, so the carry decides this one. The MD gives you one removable padded strap and molle webbing on the front. The Undeniable Backpack Duffle gives you three removable straps, two carry modes and a laptop pocket inside Under Armour.
The MD is the bigger and simpler bag of the two. The No Weigh Backpack Duffle starts at 41.5 liters and grows to 51 liters on an expandable zipper. It also carries a laptop up to 16 inches and uses UA Suspension Straps Under Armour.
The MD carries 7 liters more than the No Weigh at its widest setting, by our maths.
Is the Under Armour Undeniable duffle waterproof?
No, Under Armour calls it water-repellent. The brand's wording is that "UA Storm technology delivers an element-battling, highly water-repellent finish" Under Armour. A repellent finish sits on the face of the fabric and makes water bead and run off.
The shell is 100% polyester. Under Armour adds TPU-coated and foam-lined panels on the bottom and the sides, which it lists for durability and structure. That coated base is the part that meets wet ground in a car park or on a pitch.
Tip
Zips and seams are where water finds a way in. Give anything that must stay dry its own dry bag inside.
How much fits in 58 liters?
Under Armour's own gym bag guide puts 46 to 60 liters in the medium band. It says these duffles "should still fit in lockers, though it'll depend on what else is in there" UA gym bag guide.
The MD lands near the top of that band at 58 liters. For scale, it holds 18 liters more than the 40 liter SM, about 45 percent more by our maths. The step up to the 101 liter LG is much bigger again.
Under Armour's guide also says you should fit everything in without stretching or stuffing the bag. That matters for the zippers and seams over a long life.
Where shoes and damp kit go
A large vented pocket takes the shoes or the laundry. Under Armour lists a "large vented pocket for laundry or shoes" with internal slip pockets Under Armour. Vented means the panel lets air move, so damp kit is not sealed in.
Odor control technology sits alongside it. Under Armour lists the feature as technology that "minimizes odor" inside the bag. The same feature appears on the XS and SM pages.
The rest of the storage splits three ways. There is a large front zippered organization pocket and a dual water bottle slip pocket. Molle webbing attachment points sit on the outside.
How the Undeniable 5.0 MD carries
Two ways: by the top handle or on the shoulder. Under Armour lists a padded top grab handle. It also lists a removable, padded HeatGear strap that "easily stows away in side pocket" Under Armour.
That stowaway detail is the useful one. A strap tucked into the side pocket cannot catch on a locker door or a car seat. The LG and XL use the same removable HeatGear strap LG. The XS and SM list a plain adjustable strap instead SM.
The molle webbing on the front takes clip-on pouches. It is the same loop system that outdoor and tactical packs use.
Clip the padded HeatGear strap to both end rings and set the length you want.
Load clothes into the main compartment first, keeping the weight low and even.
Put shoes or damp kit in the large vented pocket at the side.
Use the slip pockets inside that vented pocket for small items.
Load keys, a wallet and cables into the front zippered organization pocket.
Drop a bottle into each side of the dual water bottle slip pocket.
Clip any molle pouches onto the webbing points on the front.
Close the main zip without forcing it, so the seams and zippers stay unstrained.
Carry it by the padded top grab handle for short moves.
Unclip the strap and stow it in the side pocket when you do not need it.
