This small, light backpack is simple yet sturdy and is perfect for a certain type of runcommuter. It is about as basic as you can get in a pack designed specifically for running/sports. The Speedlite 10 is a great runcommuting pack for those who value durablity, quality, and simplicity, but more significantly, those who want a pack that they can forget about while running. This is one for runners who don’t want to access much whilst on the run.
The top zip opens the main compartment from halfway down each side of the pack. Below the zip on each side is a mesh pocket with elasticized top edge that keeps the pocket in close to the pack. These mesh pockets work fine when the pack is relatively empty. When the main compartment of the pack is full, however, it’s very difficult to get a drink bottle into the pocket. This means that if you want to carry water to drink while runcommuting it has to be either a very small bottle (like 150ml) or you’ll need to use a hand-held. This could also be annoying if you are using the pack during the day and just want to have somewhere to put your full-size water bottle.
Main Compartment and Top Access Pouch
There are no compression straps on either the front or sides of the pack, but this is not really a problem, as the pack is not very deep, and this –combined with the fairly stiff fabric – means that even when the main compartment is entirely empty there is no swinging or flopping or dragging.
For its compact size, this pack holds a fair bit of stuff — enough for many runcommuters. It will take a pair of size US9.5 (women’s, US8 men’s) shoes, and a full set of pants or skirt, underwear and shirt. It won’t have room left for a jacket, however. Without the shoes, the main compartment will fit the pants/skirt, underwear, shirt and lightweight jacket.
I have used this pack in hot conditions, with my work clothes loaded in the main compartment with no plastic or other dry-bag covering. Despite my ladylike perspiration, the clothes remained dry and fresh. This is due, I think, to the thick-ish mesh back panel and the water-resistant inner coating of the main compartment. Together, these features kept sweat from soaking through. However, my longest run in these conditions was one hour, so people running longer or who are more serious sweaters (though I am not a lightweight!), may find moisture transfer occurs. A dry-sack to contain your clothes before you put the whole sack into the main compartment will also serve the function of compressing your clothes to prevent rumpling and load-bounce. (As a related point: the Deuter Speedlite 10 is too small for the iamrunbox clothes organizer).
