Crafted from an ultra high strength polymer designed to outwear some metals, nylons, and urethane. Designed for hard use and maximum UV resistance, the material has a low friction coefficient and is self-lubricating with a non-adherent surface. It's black color blends in with forest surroundings and galvanized hardware prevents rust for a long lifetime. Available in two different sizes to accommodate a wide range of cables. 

Mounts around cable and attaches to a static point with a bungee cord (not included). This brake block is sold as a component to an integrated braking system. It is designed to be used as part of a gravity based brake system and be attached to a shock cord. It should never be used alone or without a backup emergency brake in the event of a failure. There are two eyebolts installed in this block. One should be rigged to take the impact from the rider. The second should be connected to the first with a slack tether.

    Good quality, not sure on fit
    Size: X-Large, Color: Black/Mariner Stripe
    I looked at the general comment on this top and it stated frequently returned due to loose fit. My measurements are close to size xl so I figured if they run large/loose then they would fit me fine. My bust is 46 1/2" and I probably should have gone xxl. The tops are snug across my breast and I will have to be adjusting so it does not pull a gap at the side of the arm pit area. However the top is not too snug, also not loose throughout the rest of the body so don't know how I would feel about a size larger. The quality is nice, medium weight cotton. No see through and no falling in creases. I hope washing these in cold and line drying will keep them from shrinking. I will keep these because I do like the quality and length but have not decided if I will order more or not.

    Weirdest armhole proportions I've seen
    Size: X-Large, Color: Navy/Sage Green, Size: X-Large, Color: Navy/Sage Green
    There are a few nice things about these tanks -- I like the colors, there's a little extra length in the back, and the fabric is a thick quality fabric. I appreciate the fact they're 100% cotton and was looking forward to wearing these. Overall, the tanks fit as I would expect for the size. But what in the world is up with the dimensions for the arm holes? There is a significant amount of extra fabric that bunches up and looks awful (see photos) I've never had this happen on a tank top before, even one that's a size up. It's really strange and I'm disappointed that I can't keep these because of it.

    Comfortable Sleep Tanks, Weird Fit for Daytime
    Size: Small, Color: Hot Pink/Oatmeal Heather
    These 100% cotton tanks are perfect tops to wear at home: soft, breathable, and great for sleeping or lounging. The pink is extremely bright (borderline highlighter), while the beige is a much more wearable, calm color. The fit is a little odd on me—something about the cut just doesn’t sit right—so I wouldn’t wear them out of the house, but as a comfy bedtime set of two, they do the job.

    Very reasonable price for the quality
    Size: Small, Color: Navy/Sage Green
    The tank tops are well-made with quality fabric. I like the subdued colors, too. Unfortunately the tank tops don't fit me well.

    Classy cut
    Size: Large, Color: Black
    Good quality tank. Just what I was looking for. Not too short for my long torso. I’m 165 lbs and the large was just right. I’m over 60 and I don’t prefer a tight fitting tank top any more. I want a skim the body look with a bit more arm coverage. These look classy. I got the black and will order the bone color next. I will hang to dry but some reviews say it doesn’t shrink.
