None of us have mastered the art of stacking pads like Nick P from the AK factory. When he’s not making bouldering pads, he’s crafting reassuringly flat landing zones beneath the gritstone boulders of the peak.

If you’re going to have a pad party, you should always invite a Sputnik along.

Sputnik covers up the gaps or seams between pads in your multi-pad setup so you don’t fall through them. At 100 x 60 cm in size, it slides into your full pad for the walk-in, weighs less than a guinea pig, and will probably save your ankles at some point… so there’s really no reason not to take it along.

1 cm of closed-cell foam in the Sputnik spreads your weight across the landing surface. This foam lives in a tough shell of 600 denier Torino fabric with a DWR coating, so you can throw it over boggy and snowy starts no bother to keep your shoes clean.

Made by Dom and the team in our UK factory, all stress points are bar-tacked so that Sputnik is well capable of coping with the abrasive life of a bouldering pad.


We fall off things a lot, so we make crash pads that can take a lot of falls. Our foam is crosslinked – a process which bonds molecules in the foam that would not usually link together to make it much stronger and reduce break down from repeated compressions. This makes our foam more shock absorbent and durable than other foams on the market.
