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

      Dividers don’’t stay in place
      Color: Beige
      The dividers do not stay in place. It’s a great idea but not well executed because the dividers pop up or slide, leaving the necklaces to get tangled.

      Slots inside drawers are not tight enough.
      Color: Grey
      I got an earring storage bin that matches this one and I do like this storage drawer set, but the little slots that separate the necklaces move around too easily and I don’t like that. It looks classy with the other stack I have.

      Great Tray For Storing My Everyday Carries
      Size: 8.5" x 5.8" x 1.9", Color: Black
      My everyday carry items (wallet, keys, etc.), used to just get thrown around wherever when I'd get home, but this little tray makes a great, defined, space for me to keep those things when I don't need them on me. The soft lining reduces the obnoxious sound of throwing keys on a hard surface, and of course keeps me from scratching up a surface. The build feels quality and I haven't seen any damage to it yet. Also the all black version with gold buckle looks quite good and adds a subtle touch of luxury. Absolute recommend for the price.
