Wilderness Equipment Slipstream 25 Litre Canvas Commute Day Pack

The Wilderness Equipment Slipstream was inspired by WE's own cycle commuting requirements and for many it has been their lifelong daypack. The inward facing zip and sloping top panel give this bag the best possible water-shedding, weather-resistance. Immediately you start using this pack you will discover its convenience: Push back the unzipped bag canopy and the entire contents can be easily viewed and accessed. Selecting from the contents is a breeze. With 25 litres of usable capacity this rugged daypack is ideal for just about every trans-urban, work-day journey.

Sizing and Fitting Your Wilderness Equipment Backpack

Where a daypack is not fitted with a substantial hip harness WE specify the back length so you can judge how it might rest on your back. Some long daypacks may be too long for use on very short torsos.

Where WE quote a back length of 450mm this is the distance from base seam on the harness panel up to either the shoulder harness top stabiliser strap anchor buckles (if present), or otherwise, the seam where the fixed shoulder harness arms attach to the pack bag (as with the classic canvas daypack models). Our daypack back lengths are either 400mm (S), 450mm (M) or 500mm(L).

You can think of these lengths as corresponding to the backpack sizes S, M and L for packs that ARE fitted with substantial hip harness systems. If you are a size L in this type of pack then you will also be able to comfortably carry a 500mm back length basic daypack.

The majority of WE's simple daypack models are 450mm, suitable for all but the shortest torsos.

Steps to Measuring Your Back Length

Measure the vertical distance from the crest of your hip bone up to the level of your shoulder surface, where the pack shoulder harness will rest. Find the top of your hip bone (pelvic crest) on one side. Hold the end of a tape measure on the bone. It slopes down as you move along it towards the front centreline of your body. Find a position directly down from a point on the corresponding shoulder at the place where the shoulder harness arm will cross it. Now, extend the tape measure vertically upwards from the hip bone and, at the same time, rest a ruler or other straight edge horizontally on your shoulder, extending forward from where the shoudler harness padded arm will rest. Ask someone to help out with this. Read off and note the distance where the shoulder level meets the tape measure.
