Cupboards, wardrobes, chests of drawers, garages, sheds...
You name it, we've managed to fill it with everything from boots to axes, crampons to rucksacks.
Whilst on the topic of rucksacks... it's totally ok to have about 8 for every conceivable activity?
Well, deep in that cupboard or shed, you must have a favourite piece of kit, or one trusty item you'd not be without?
Cotswold Outdoor want to know about it!
Happy feet = Happy Kate!
The North Face boots got me up Kilimanjaro pain free (we'll ignore the dislocated kneecap for now)
And the Scarpas? Well, they feel like slippers on my feet now!
Perhaps it's the backpack that got you up your first mountain? Your trusty bombproof water bottle? A coat that literally saved your skin?
The best entries will win a piece of brand new kit from Cotswold's Autumn/Winter range and feature on the brand's Instagram & Facebook pages, plus online via cotswoldoutdoor.com/thekitmuseum :)
Some of the prizes up for grabs include a Rab Continuum jacket, Fitbit Iconic, GoPro Hero 5 Session and Garmin Vivioactive 3 GPS.
Pretty incredible, right?
So get sharing, make sure you use the #TheKitMuseum on Instagram and Facebook and also let me know what you love below (purely because I'm nosey).
