The O'Brien Siege is the waterski built to perform on a budget. Built with a forgiving fibreglass and polyurethane construction, O'Brien makes the Siege forgiving underfoot with a comfortable amount of flex to support skiing at beginner speeds but still stiff enough to turn a buoy in the course. The design principle on the shape of the Siege is designed to work with the core, creating a ski that will create edge turn and hold with ease while also creating consistent, comfortable and effortless transitions in the turns. Altogether, the O'Brien has developed the perfectly rounded kids ski, one ski to rule them all.

The O'Brien X9 waterski boot is built with base-level comfort and ease in mind, taking the core components of a ski boot to make it easy for kids and adults alike. A simple neoprene liner sitting above a plush EVA footbed gives you comfort from underfoot all the way through to your upper ankle. Underneath this is O'Brien's signature superlite chassis that gives you the perfect weight balance with your ski.

Waterski Features

Rocker

  • Flat Spot - Underneath your front foot gives you comfort and stability while also propping you up higher on a platform for control throughout your entire motion from cut to turn.
  • Continuous Rocker - Through the tip and tail allows the ski to always provide a constant level of speed across the wash and allows for a smooth, comfortable turn, drive through the wash, while still having the ability to easily keep that speed into your leading edge.

Flex

  • Flex Rating(1=Soft, 10=Stiff) - 5/10

Core

  • Closed Cell PU Core – The most well-known core in waterskiing, with a tighter knit construction to reduce weight while remaining durable and providing a slightly softer feel meaning you can ski for longer, feeling less tired, while also getting more flex into turns and less rebound when crossing the wash

Laminates

  • Fibreglass Laminates – The most forgiving top layer you can get, a simple fibreglass laminate allows the ski to provide a comfortable flex and smooth arcing turns.

Shape

  • Small Defined Edge Bevel - This makes it easier to turn and lean into your edges and hold the edge through the wash.

Concave

  • Rapid Response Tunnel - O'Briens signature tunnel shape designed to transition from edge to edge with ease and create easier hold through the turns

  • Polished Speed Base - All about promoting greater water flow across the base of the ski to ultimately reduce drag

      Wonderful
      Fantastic buy! This contains everything I need (minus a phone), and because it zips up, I know everything is secure. I recommend this product.

      Exactly what I needed for traveling!
      This Amazon Basics Travel Passport Wallet Organizer is amazing value for the price. It has multiple easily accessible slots & pockets that can be used for credit cards, boarding passes, receipts, pens, and currencies if traveling internationally. The wallet has a zipper which can safely secure folded documents such as immunization records, marriage certificates, and citizen forms if needed. The functional design is larger than I anticipated and the material feels well-made, solid, and looks nice. I could not fit the wallet in my pocket, but it easily fits into a backpack or purse. If I happen lose this or misplaced this one, I will be purchasing this again.

      Great Hold-All
      This seems to be well-made and I like the configuration. It should hold passport, ID, credit cards, cash and any travel docs with no problem. It is a bit larger than I expected, however, so that will have an impact on what sort of purse, belt bag, or etc. I use to carry it. My biggest issue with this and ANY RFID blocking wallets/purses/etc. is that I wish the manufacturers would add a sewn in tag or imprint on the product itself that SAYS it's RFID blocking. After time goes buy it gets hard to remember which items in your travel stash are or aren't. I've used a Sharpie to mark this one, but it would be nice if the manufacturer did so professionally.
