Skis - Keep them light. We will tour roughly 4000 feet/day and you want enough gas in the tank to enjoy the down. Most people have a ton of fun on a ski that is between 95mm-115mm. Mark will be using the DPS Wailer112 Tour1 skis. Other good models are, Dynastar Cham 105, LaSportiva Vapor Nano, K2 Comback, and so many others. If you question between which ski, just ask. Try very hard to keep them under 9 pounds/pair or 2041 grams/ski
Bindings - Dynafit style bindings are almost mandatory. They are 75% lighter and work. Mark likes the TLT Superlite 2.0.
Poles - 2 part adjustable is nice like these BD Pure Carbon.
Boots - Whatever fits. Mark will be in the Dynafit Vulcan, the TLT 6 Performance great too. LaSportiva Spitfire 2.0 are good for those with narrow feet. Scarpa's are good too. Mark then upgrades his boots with the Intuition Pro Tour liner for a perfect/warm/comfortable fit.
Beacon - Any three antenna beacon is fine. Mark likes the Pieps DSP Pro
Shovel - Any metal medium-small sized shovel is fine. Mark likes the BCA B-1
Probe - Any metal or carbon fiber probe 240 cm or longer.
Airbag Pack - Not mandatory, but could be good. Flying with a canister can be annoying as you need to fly with it empty, and then find a location to refill. The Black Diamond Jetforce packs are a good option as you can fly with them. You will need the largest size they make to fit everything in it. 95% of people will use a standard pack for the weight savings and convenience.
Pack - Mark likes the Arc'Teryx Khamski 38
Harness - Keep it simple and light. CAMP Alp Race is the bomb
Boot Crampons - Aluminum style are great and light for what we will be doing. Race 290 are great.
Ski Crampons - for biting into early morning spring hard pack. Dynafit are the best/lightest
Ice Axe - Light is right, nothing too crazy needed here. Corsa is a great choice, or Corsa Nanotech for one that is a little more beefy.
3 Locking Carabiners - Black Diamond Nitron and HMS Nitro
4 Non-locking Carabiners - Photon Wire bent gate
1 Petzl Tibloc, 1 Sterling Hollowbloc 13 inch, 1 Dyneema double-length sling CAMP, 1 Sterling PowerCord Cordellete. All these will be for crevasse rescue purposes.
Helmet - Normal ski helmet will work but are heavy, Mark likes a climbing helmet. Speed 2.0
Mark will provide the ropes.
Keep it simple. Layer well. Stay comfortable. Arc'Teryx makes the best ski clothing. Here are the layers Mark will wear. All are Arc'Teryx unless noted. You can use this as a guide to pick and choose your layers that are similar.
