I originally had The North Face FL Race Pack, but alas one of the bungee chords broke and North Face were unable to repair so they kindly offered a suitable replacement, of which I chose this one.  It is designed for adventure racing and endurance events boasting a 13L capacity along with 2 x 0.5L bottles in the hip based water bottle pockets.  It’s long design means it fits to the shape of your back quite nicely and with wide shoulder straps along with the hip belt having an offset buckle the pack sits well without any pressure points of note.

There are two large zipped pockets on the hip belt ideal for stashing gels & snacks and the pack can take a 2L hydration pack (camelback) as well.  If you need to stash your trekking poles there are double trekking pole loops and reflective exterior lash loops to keep them in place.  The lash loops could be used to attach other bits of equipment as needed too.

The pack itself weighs 383g and the 2 bottles provided weigh an additional 150g (empty, obviously).

I found that the location of the water bottles takes a bit of getting used to as I have always run with bottles on the front, around the chest area, but it was a nice change not to have all that on your chest and the cross over velcro chest strap fits really comfortably, particularly for women as the velcro connects in-between the breasts so there is not that feeling of breast compression and they can breath!  This velcro strap also has a nice little mesh pocket which I find absolutely ideal for my chap stick!  The only downfall of this bag to me is I can’t fit my iPhone in the hip zip pockets as they make iPhones too big these days, so it is a bit of a faff having to stash it in the back, though as my husband would say, if you’re racing you shouldn’t have time for taking photos (or texting!) but I do enjoy a #runselfie or two whilst I am out.
