Description

ISM PN 3.1 SaddleISM proudly introduces the PN 3. 1. Starting from our PN 3. 0 chassis, we added more padding for riders who prefer a slightly softer ride. With a 120mm rear end and and tapered edges, the PN 3. 1 is so comfortable, it will disappear underneath you. Similar to the other PN saddles, the PN 3. 1 offerings superb thigh and hamstring clearance. This allows for more rider body movement around the seat, and is great for diving into fast corners. Like all ISM

 ISM proudly introduces the PN 3.1. Starting from our PN 3.0 chassis, we added more padding for riders who prefer a slightly softer ride. With a 120mm rear end and and tapered edges, the PN 3.1 is so comfortable, it will “disappear” underneath you.

Similar to the other PN saddles, the PN 3.1 offerings superb thigh and hamstring clearance. This allows for more rider body movement around the seat, and is great for diving into fast corners.

Like all ISM saddles, the PN 3.1 is nose-less and designed to remove pressure from soft tissue, ensuring maximum blood flow, no genital numbness, and a healthier, more enjoyable ride.

This saddle is not recommended for cyclists who ride with a high seat position or those who ride very forward on the extreme front of the saddle (the front arms or the nose of a traditional saddle). The recommended seat height for these saddles calls for a 32-37 degree knee bend for the rider. If you ride with a minimal bend or a straight leg a different ISM saddle is recommended for you.

Key Features

  • All-new saddle shape

  • Auto-racing inspired air vent chassis

NICE Shirt that SHRINKS!!
Fit Type: Regular Fit, Color: Blue, Size: X-Large
Loved this shirt right out of the package. Put a little steam pressing on it and it was perfect. Has a thicker softer feel than most casual dress shirts. Ordered XL with the "regular" fit and it could be worn tucked or out without it looking overly blousy. SADLY, after a first wash on cold and tumble dry low, and pulled it out early and it shrunk by almost a full size!!! The sleeves, length of shirt and overall fittage shrunk so that now it fits like a snug large. I've never had a shirt shrink like this, hence, the one star off. I would have given it 2 stars off, but the original quality of the shirt is nice, just beware of the shrinkage factor. Don't put it in the dryer at all, only air dry it. I'm tempted to reorder another but just then never put it in the dryer.

nice fit
I am thoroughly impressed with this Amazon Essentials white shirt. For the price, the quality is outstanding. The fabric feels soft, breathable, and has a good weight to it

Nice shirt, great price.
Fit Type: Regular Fit, Color: White, Size: Medium
Worn it twice and I find it very comfortable. I wear it outside and casually to protect my arms and neck from the sun and find it more comfortable than a long sleeve t-shirt. The price is comparable. If I was to wear it to the office it would have to be ironed. I bought one shirt to try it and I will be buying more.

Nice shirt!
Fit Type: Regular Fit, Color: White, Size: X-Large
I added one of these shirts to another order just to see if they were any good. I was pleasantly surprised by the quality. It fits perfectly and looks pretty nice for a low cost casual dress shirt. Materials seem decent quality. Comfortable, soft fabric. Didn’t shrink too much in the washer and dryer. We’ll see how it holds up long term but so far so good
