How the comparison works

Your choices are compared with each model’s product details. A missing or conflicting value stays unknown and cannot satisfy a choice you select. The starting order helps you browse; it does not rate real-world performance.

Source dates appear with each link below. A source date does not confirm today's price or stock.

Fit and load can separate deuter packs with similar volume

deuter's Futura 30 SL and Speed Lite Pro 30 each hold 30 L, but their recommended back lengths differ: 38 to 48 cm for the SL and 44 to 54 cm for the standard model. The empty weights are 1330 g and 760 g respectively. Volume alone leaves both the fit and carrying-weight differences unresolved.

Across these packs, volumes span 13 to 32 L and empty weights 390 to 1350 g. The Speed Lite Pro models have recommended load ranges of 6 to 10 kg; the Speed Lite models have ranges of 2 to 5 kg. A larger volume does not automatically mean a higher recommended load.

Measure your back length and weigh your gear. The range selectors match complete maker ranges, so they do not calculate fit from an individual measurement. Exterior dimensions remain separate from volume, and SL variants remain separate from standard versions. Loaded packs have not been carried for this reading of deuter's fit and load guidance; use the exact model's fitting instructions before choosing a size.

Before you buy

Why does a Futura weigh so much more than a Speed Lite Pro?

The figures here don't explain it. The Futura 30 SL weighs 1,330 g against 740 g for the Speed Lite Pro 28 SL, and both are SL packs with the same recommended load, while the Futura 27 and 32 weigh 1,250 and 1,350 g yet are recommended for 4-8 kg. Read deuter's feature list for each to see what the extra grams buy before you pay for them.

What if my back length falls between the two ranges?

The two ranges overlap by 4 cm, so if your back falls in that band, either fit is in play. The back-length menu shows one range at a time, so run it once for each and compare the two lists side by side.

Does a bigger pack carry more weight?

Not reliably. The Speed Lite Pro 19 holds 19 L with a 6-10 kg recommended load, while the larger Speed Lite 21 is recommended for 2-5 kg, and the 24 L AC Lite 24 sits between them at 3-6 kg. Pick volume for your gear and let the recommended load decide the weight question.
