Description

Mountainsmith Mayhem 45Why compromise when you don't have to? The Mayhem 45 is ultralight, ultra durable, and ultra comfortable. Built with Spectra Fiber, the pack offers a top tier strength to weight ratio. Used by military and law enforcement, Spectra Fiber is an ultra high molecular weight polyethylene known for its lightweight strength and abrasion resistance properties. In the Mayhem 45, this means more efficient pack carry, more mileage, and a lifetime of adventures.

Why compromise when you don't have to? The Mayhem 45 is ultralight, ultra-durable, and ultra-comfortable. Built with Spectra® Fiber, the pack offers a top tier strength-to-weight ratio. Used by military and law enforcement, Spectra® Fiber is an ultra-high-molecular-weight polyethylene known for its lightweight strength and abrasion resistance properties. In the Mayhem 45, this means more efficient pack carry, more mileage, and a lifetime of adventures. Less pack weight also means more room for the essentials - like melted chocolate bars and squished PB&Js.

At 45 litres, the Mayhem 45 is designed for one-to-three-night backpacking trips, backcountry huts trips, gear heavy days at the crag, and adventure travel. The hybrid top and panel opening offers easy access to the front of the pack, a must-have for tight environments and organized packing. Toss the Mayhem on your back and the hex-ridged EVA back panel padding allows for omni-directional airflow while the sock-style shoulder strap construction prevents the straps from digging into your body. The Interfaced Waistbelt system is designed and patterned to flow into the back panel allowing for a lightweight but intimate suspension fit and high levels of stability and comfort.

Jobsite Workhorse
Style: WF-7840, Set: DUAL TRAY (500 sheets)/FAX/ADF/PRINT/COPY/SCAN
Have had previous models of this printer and they have always been solid. We use them in our office trailers on our construction jobsites and this new version works excellent just as the previous series did.

Excellent, as long as you don't update firmware
Style: WF-7840, Set: DUAL TRAY (500 sheets)/FAX/ADF/PRINT/COPY/SCAN
About 6 months in, and I am very happy with the performance of this printer. I loved that it collated multipage documents without being told to! I have denied every request for firmware updates, and I am pleased to report that remanufactured ink cartridges (pronounced "more affordable and just as good") work just fine. DO NOT UPDATE THE FIRMWARE. The updates only serve to make it impossible to use off-brand or remanufactured ink cartridges.

Vibrant, Rich Colors
This is my absolute FAVORITE sublimation ink. For the price, it's the best you'll find the canisters are easy to use, don't leak, and lasting for months. The bottles fit perfectly onto the eco tank. The colors are vibrant, rich, transferring to piece exactly as it should. These work like a dream and I'm a loyal customer, for sure.
