Price is for a pair of Shocks

The Sheaveless Block - Available in four colour options - blue, green, grey and red with several attachment options, including webbing, pigtail, lashing and dyneema links, it will be the obvious choice for those kitesurfers, paragliders, control line deflections and purchase systems that require a lightweight high load capacity block.

Ultimate durability - With no moving parts SHOCKS provide ultimate durability and are maintenance free. They are ideal where sand and grit would compromise a bearing system or where regular flushing out isn´t possible. Their gentle 3-dimensional geometry is kind on lines, but is strong enough to cope with poor leads.

Soft attachment specialists - SHOCKS are designed primarily for ´soft attachment´; spliced to a line end or lashed in place. The elongated attachment aperture is also ideal for webbing attachment, ensuring the intended orientation is maintained.

Virtually limitless applications - The applications for SHOCKS are virtually limitless, including numerous high performance dinghy and small sailboat rigging applications including tweakers, vangs, trapezes, cunninghams, barber haulers and kite bridles. They are also handy on larger boats for uses such as lazy jacks, sail covers, tie-downs, ladder and motor hoists.

Hidden performance - Constructed from anodised aluminium and weighing a mere 2.5g, SHOCKS are outstanding performers in the strength and weight stakes. The clever design and exacting finishing also provide excellent free running at moderate changes of angle. Small & hi-tech line specialists SHOCKS accept lines from 1.5 mm up to 5 mm and function just as well with hi-tech uncovered braids as with traditional double braids.They are available in colour choices to help keep complicated rigging configurations more organised.

A true turtleneck that retains a snug high neck.
Color: White, Size: X-Large
I've found this brand to have gotten better over the years as far as offering the American market what it needs in terms of realistic sizing. I only wish they'd realize that there are a lot of us who are long in the back and arms where my only choice is to go a size up and sacrifice a slim fit for sleeves that are long enough plus a back that doesn't go up past my waist just because I reach up for something, that and I like to be warm. So these are such nice quality turtlenecks that it's hard to complain about but maybe the company will read this. The snug neck stays up is plus number one since that's why I'm buying a full neck. They come with very nice weaves in the fabric, good enough for casual or formal wear. Finally the warmth you seek is there but I've worn them in what most would think isn't the right temp for a turtleneck. Also they have them in white! Yes, a lot of others just don't for reasons I can't fathom, and the pic you're seeing is accurate, these will form to your shape without being ridiculously thin material. Several washes later and they are as fine a garment as when I first wore them. I've only found one other brand that compares to these but it's much more expensive, COOFANDY is affordable in these times of expensive everything. Warm but also a lightweight shirt, I've gotten them really dirty with actual dirt and it washes out so well you'd never know it. Don't let my taking off one star stop you, try one yourself and you'll be coming back for more.
