Description

ISM PN 4.0 SaddleThe ISM PN 4. 0 is the newest offering in the Performance Narrow category of saddles. Similar in design to the award winning ISM PN 3. 0, we increased the sit bone contact points 5mm to accommodate a range of pelvic body positions. Rider response told us some cyclists wanted a 125mm saddle to allow for more relaxed pelvis tilt related to road and gravel cycling. Like the other PN saddles, the PN 4. 0 offerings superb thigh and hamstring clearance.

The ISM PN 4.0 is the newest offering in the Performance Narrow category of saddles.  Similar in design to the award-winning ISM PN 3.0, we increased the sit bone contact points 5mm to accommodate a range of pelvic/body positions.  Rider response told us some cyclists wanted a 125mm saddle to allow for more relaxed pelvis tilt related to road and gravel cycling. 

Like the other PN saddles, the PN 4.0 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 4.0 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

  • 5mm wider than the PN 3.0 to accommodate a greater range of sit bone width
  • Tapered-edge mold design for incredible comfort
  • Auto-racing inspired air vent chassis

 

Commonly Used For

  • Gravel/Road bikes
  • Time Trial bikes

Luxury Comfort and Perfect Support – Best Pillows Ever!
Color: White, Size: King Size Set of 2
I recently purchased the Serta Hotel collection Pillows White Goose Feather Down Fiber Gusseted, and I couldn’t be happier with my choice! These pillows are the perfect balance of softness and support — plush enough to feel luxurious, yet firm enough to keep my neck properly aligned all night. The gusseted edges really make a difference, helping the pillow hold its shape and look full even after weeks of use. The quality of the materials is excellent — the outer cover feels smooth and breathable, and there’s no feather poking out like with cheaper options. I also appreciate that they fluff back up easily after use, making the bed look hotel-perfect every morning. If you’re looking for comfortable, high-quality pillows that provide great value for the price, I highly recommend these. They’ve truly improved my sleep!

Good quality pillows
Color: White, Size: Queen Size Set of 2
These are very soft and supportive as advertised. W find them a little too thick for my taste (why I only gave 4 stars), but personal preference is very subjective with pillows. They are well made and high quality, and am happy with my purchase.

Overall, not that comfortable!
Color: White, Size: Queen Size Set of 2
Only okay. I find these pillows to be heavy, and not very conforming. Overall, not that great.

goose down pillows.
Color: White, Size: King Size Set of 2
Since receiving them, these king-size white goose down pillows have truly transformed my sleep. They are incredibly soft and fluffy to the touch, so plush it's hard to believe they hold their shape. Sleeping on them is like lying on a cloud. The 100% cotton cover adds extra comfort: it feels cool to the touch, breathes well throughout the night, and helps me maintain a comfortable temperature while I sleep. Furthermore, the "reinforced fiber" structure is noticeable: after several weeks of use, the pillows retain their support; they don't clump or lose their shape, ensuring consistently good rest. I find they have the ideal balance between firmness and softness: firm enough to support my neck and head, yet plush enough to adapt to my posture without creating pressure. This has improved my nights; I sleep more soundly and wake up with less stiffness in my neck. In short: these pillows combine luxury, comfort, and durability. If you're looking to improve your sleep quality with soft, firm, and breathable pillows—especially in king size—these are perfect. Definitely one of the best investments you can make for better sleep.
