A lightweight, windproof and fast-drying layer with added warmth for hiking and running in the mountains.
  • Ideal for: Mountain Walking & Trekking, Mountain Running, Mountaineering
  • Weight: 300g/10.6oz (Size L)

For many of our staff and team members, the Aerotherm Jacket is their go-to item for fast-paced mountain days in moderate weather. It’s one of the most versatile jackets in our range because it meets the demands of almost any mountain activity. It seamlessly combines wicking capability with windproof protection to create a layer you can wear all day, whether running, hiking or climbing.

The Aerotherm uses a windproof EXOLITE 45 double weave soft shell for its outer layer. Lightweight, breathable and with a slight stretch, this is an ideal protective fabric to keep the wind at bay while still being comfortable and mobile. Inside the jacket, a soft and highly wicking micro-grid lining efficiently draws away moisture during focused uphill efforts, wicking away sweat and preventing discomfort. This layer also provides some valuable warmth on exposed summits and ridgelines. Together, these layers dry exceptionally quickly and help keep you comfortable in changeable mountain conditions and through stop-start activity.

Designed with a slim, Active fit to minimise excess fabric, the Aerotherm layers well under a waterproof shell when necessary. It can be adjusted at the hem using a drawcord to fine-tune fit, and the cuffs are elastane bounds to keep the wind out. An adjustable Mountain Hood with an elasticated border offers secure protection when running or in strong winds but can be rolled away when unnecessary. The microgrid lining is reversed throughout the arms to prevent catching or binding with other layers, and the articulated sleeves are unrestrictive during technical scrambling and climbing. Zipped hand pockets and a chest pocket store essentials, and the jacket packs neatly into its hand pocket with twin carry loops for easy carrying in a pack or on a harness.

Great product
Size: 1 Count (Pack of 1)
This stuff provides a smoother acceleration and overall effectiveness for the motor. With the added benefits of lubricating the fuel pump?

If you own a diesel engine, use this.
Size: 128 fl. oz, 1 Pack
For diesel owners looking to protect their fuel system, Hot Shot's Secret Everyday Diesel Treatment (EDT) is a heavy hitter in the world of additives. This 1-gallon jug is designed for the long haul, treating up to 1,280 gallons of fuel, which makes it incredibly cost-effective for daily drivers and fleet owners alike. The primary draw here is the 7-point cetane boost, which noticeably smooths out rough idles and improves cold starts. Beyond performance, it serves as a critical insurance policy against modern "dry" Ultra-Low Sulfur Diesel (ULSD) by adding essential lubricity to the fuel pump and injectors. It also features a demulsifier to help separate water from the fuel, preventing corrosion before it starts. While the 1-gallon bottle is bulky and requires a smaller dispenser for easy pouring at the pump, the peace of mind and improved MPG make it a staple for maintaining a healthy engine.

TDI Seems To Like This Stuff. A Must For US D2 Fuel.
Size: 1 Count (Pack of 1)
After purchasing our 2012 VW TDI diesel at 140K miles I started researching best practices to keep these little engines happy. What I read was that the US has some of the crappiest quality D2 diesel on the world stage. Even Canada's diesel is higher cetane and lubricity rated than the States not to even mention Europe which has WAY higher standards than us. The weak point of these TDI engines seems to be the high pressure fuel pump (HPFP) that is crank driven to enormous pressure for the injectors to to their thing. If these HPFP parts fail on common rail engines they can literally grenade and throw shards of metal everywhere within the downstream fuel system ensuring a VERY expensive repair if not destroying the engine altogether. The lubricating property of the fuel plays an important part in keeping these pumps working properly. There even seems to be some data supporting Canadian operated TDIs have fewer failure rates of the HPFP than stateside fueled vehicles although nothing had been officially published to my knowledge. Sulpher in the diesel had beneficial lubricating properties but was bad for the environment and subsequently removed from D2 by the EPA much like leaded gasoline of yesteryear. So the second tank I ran in my TDI was Hot Shot's EDT. I can't comment on the comparative difference as I ran this from almost day one. What I like is the claimed increased lubricity and cetane boost that is supposed to bring our crappy D2 up to reasonable levels the rest of the world enjoys. Fuel economy seems fine but playing with a low spun turbo and the subsequent torque is sometimes too irresistible to give fuel economy a fair chance. Besides, I need to blow out all that accumulated carbon :) I like the fact that the Hotshot's EDT seems more concentrated and affordable than the competition. 1oz for a tank is almost a performance treatment for my TDI. It's a negligible cost for a fill up and I hope they keep it that way. My dislike might be the one thing other people love about this product and that's the bottle. The bottle is meant to be squeezed to get the measured amount in the top fill area so measuring is easier. My concern is the filler neck is not long enough to cram into the filler to avoid spilling without a funnel and diesel doesn't do many favors to paint. My workaround was to save the empty bottles from other gasoline treatments and use a syringe to fill 1oz amounts of EDT and place in the trunk of the car in double plastic bags. Seems to work fine although the kitchen was probably not the best place to do this since it doesn't smell like flowers. Next purchase will likely be the bulk bottle. It's kind of a shame we actually need this kind of protection now since the US fuel standards are almost non-existent. Even B1 blended bio diesel would be a huge improvement in lubricity but not available where I live. Thanks Hotshot's...Good stuff!

Recommended by John. So far great additive for the CP4
Size: 16 Fl Oz (Pack of 2)
I have a ‘22 6.7 Powerstroke w/27k and pull heavy trailers in FLA. I’m worried about the (disco party). John I believe from the Ford Dealer in Hereford, Tx recommended this. I run 2 oz per fill and will see what happens. I’ve got Five fill ups on it now and seems to help responsiveness. Proof will be in the pudding. So far I’m pleased
