AV Spelshoulder Pro
The Speleo Pro is simple to wear, fully adjustable, and comfortable.
With two buckles for sizing, it can adjust from the very small to the really rather large caver. The Speleo Pro also uses the small buckle found on pretty much all harnesses these days (apart from Petzl models), which is very helpful in caves due to its speed of adjustment; the caver can change from crunched over (for sit-stand) to upright (for rope walking) to very slack (for actual caving)in very little time.
The tape is 38mm wide and therefore spreads a load nicely across the shoulders. It comes with two small gear loops at the front (knife / spanner size) and also has four bigger gear carrying loops which are useful for clipping cowstsails, and also rigging kit when actually working on pitches. These normally are located out of the way under the armpits.
The Speleo Pro is a nice combination of the user-friendly and the technical, while still being pretty compact and affordable. It can be fitted higher under the armpits than the Spelshoulder Basic, and is possibly more suited to female cavers.
