Minimalist weight = 475g (each), 950 grams per pair. Without side compression straps, front framesheet, or side roll top clips. Full Featured weight = 560g (each), 1120 grams per pair
- 100% WaterproofMade from TPU fabric with Hypalon reinforcements, fully welded seams, and a roll top enclosure. You can be fully confident that your gear will remain dry and protected, even if you don’t quite make that stream crossing.
- 13 Liter Capacity Not all trip segments have resupply options. When you need room for some extra food and water the Ponderosa Pannier’s 13L capacity will be ready. The 13L capacity is measured while still rolling the closure three times.
- Outer Framesheet To provide even compression we’ve added an outer framesheet to the bag. This allows our 13L bag to evenly and securely slim down to clean and narrow package when needed. The sheet is also removable to use as a cutting or charcuterie board.
- No Floppy Bags Here! The lower compression strap design comes from the back of the bag, loops through the rack, and hooks to the front. This allows it to double as the attachment and compression strap.
- Replaceable Straps All compressions straps are removable and replaceable. Prefer to compress the pannier like a dry bag? A mouse chew through one? No worries, we’ve got you covered.
- Silence is Precious We head out into wilderness to escape noise. We made sure that all contact points between the Ponderosa Pannier and rack are silent, secure, and strong. No more rattling, and clanging bags.

Impressive Sound Deadening Solution with Enhanced Audio Quality
Model: NewSLS50_52
I recently purchased the Siless 50 mil (1.3mm) 52 sqft Car Sound Deadening mat, and I am delighted with the results it has delivered. Right from the start, I was impressed with the packaging, which ensured the product arrived in perfect condition.
One of the standout features of this sound deadening mat is its ease of use. It was a breeze to cut and modify according to my specific needs. Whether I needed to cover specific areas or customize the size, the mat accommodated my requirements effortlessly. This flexibility made the installation process a breeze.
The Siless Sound Deadening mat has proven to be highly effective in reducing outside noise within my vehicle. With just a half cabin install, I noticed a significant reduction of approximately 10 decibels, making my driving experience much quieter and more comfortable. The mat acted as a reliable barrier against external noise, allowing me to enjoy a more peaceful ride.
Furthermore, the sound quality from my vehicle's audio system experienced a noticeable improvement. The Siless mat effectively dampened vibrations and minimized resonance, resulting in cleaner and more refined audio output. The mat's thickness of 50 mil (1.3mm) ensures optimal sound absorption, contributing to its effectiveness in creating a quieter and more enjoyable driving environment. I can now appreciate the full range of tones and enjoy a more immersive music experience during my drives.
Overall, I highly recommend the Siless 50 mil Car Sound Deadening mat for anyone seeking a reliable and effective solution to reduce noise and enhance audio quality in their vehicle. The easy cutting and modifying process, along with the excellent packaging, contribute to a seamless installation experience. With a significant reduction in outside noise and an improvement in sound system performance, this sound deadening mat has exceeded my expectations.

Good quality sound deadener at a good price.
Model: NewSLS50_52
Quality sound deadening that adheres to body panels well. You can easily hear the vibration reduction after just the first piece by tapping on the body panel before and after.

Good stuff at a good price
Model: NewSLS50_52
Works well and sticks well. I used a roller and it has been over a year and everything still sticking as good as day i put it everywhere. I didnt use any adhesive but I did wipe everything down with acetone before I applied. Good stuff at a good price

BUY THIS ONE!
Model: NewSLS50_52
This is one of the good ones. There are other brands just as good, and manny brands are worse, but this handles well, rolls down easily, doesn't come off at all easily, and adapts to dips and curves like a champ.
Appropriately heavy and dead, I'm happy with the way it smothers panel resonances and even at muffling direct sound, like a big hand over my Uncle Harry's eternally noisy mouth. You can rip the foil but you have to work hard at doing that.
Remember to buy a brayer; you can roll overlaps nice and thin. Also remember to pre-wipe the sheet metal with a decent solvent like acetone or Stoddard/Varsol. It should last forever.
