Product Overview

Our M18™ 4-Gallon Backpack Sprayer w/ SWITCH TANK™ delivers the industry's best pressure control with no manual pumping and an interchangeable tank design. Designed to meet the needs of professional landscape maintenance, the battery-powered backpack sprayer provides instant, constant, and adjustable pressure up to 140 PSI and a 24 ft vertical spray distance. The 5-mode flow rate knob adjusts the flow by 0.1 – 0.52 GPM, giving you the capability to complete a wide range of applications. Our M18™ REDLITHIUM™ XC4.0 Battery (sold separately) provides you with up to 20 tanks of spraying per charge (on Mode 3). The 4-Gallon Sprayer Tank Assembly features a dual diaphragm pump for longer pump life and Viton® seals for increased durability against harsh chemicals. The sprayer tank has an optimized design for better weight distribution, a wide mouth opening for easier pouring, and a strainer that filters debris from getting into the tank. The backpack frame includes padded straps, lumbar support, and a hip belt, giving you added comfort during extended spraying applications. The 4-Gallon Sprayer is made up of two components – the M18™ Powered Base and the 4-Gallon Sprayer Tank Assembly.

Cute striped athletic tank
Size: Large, Color: Pink Purple Stripes
such a cute and comfortable athletic tank to wear for many activities! The material is lightweight and breathable but is also so soft and makes wearing it super comfortable for any athletic activity or just for wearing casually on a hot summer’s day. The fabric seems very high-quality and has some stretch to it. The tank top does fit true to size. The collar is a very cute detail and makes this tank top feel fun and flirty and feminine. I love the pink stripes pattern. It looks cute tucked into a skirt or shorts. This is a cute tank top for Pickleball, tennis, golf, or simply just running errands. This has washed well and I usually hang up to dry all of my athletic wardrobe. It does dry quickly and does not dry wrinkly even when just clipped up to dry. I think it is a good value for the tank top that you get and definitely looks like it came from a sporty sports outlet and definitely doesn’t look or feel cheaply made. Very happy with this tank top and would definitely recommend!

Good Quality, Runs Small
This top is just as described. Great color and quality. Fabric has some stretch. Would be great for golfing. I usually wear an XL, which is what I ordered. The shirt is very snug. I prefer tops be more loose so if you are the same, definitely size up! Good value though for the quality.

LOVE this brand
Size: Medium, Color: White Blue Florals
Okay I am really falling in love with this brand I have a couple of shirts and dresses and pants and I absolutely adore all of them. The material all of it is so much better, such top quality and extremely soft and wonderful feeling up against your skin more so than you would ever think. The size is perfect I ordered a medium and I normally wear a medium, it is perfect for playing golf or tennis, it is breathable so as I run the wind cools me off. I like the way that the shirt looks and it stretches a bit so you can you know get it on but it does not lose its shape or anything like that. It washes and dries very well it keeps its shape and does not shrink and honestly in my opinion it it feels like it gets softer the more you wash it the more you wear it I don't know

Pretty in pink!
Size: Small, Color: Pink White Florals
I ordered this top in the pink color, and it is absolutely lovely! The print is feminine and cheerful, making it perfect for golf, tennis, or any casual summer outing. The fabric is soft, lightweight, and breathable, which is a must for warm weather. It does a great job keeping you comfortable, even on hot days, and the sleeveless design allows for easy movement. My only note is that the fit runs a bit snug. If you’re between sizes or prefer a looser fit, you may want to consider sizing up. Other than that, it’s a very well-made top with a flattering style and beautiful color. Overall, a pretty and comfortable addition to any warm-weather wardrobe! 💗⛳🎾☀️

Lightweight, Great Quality, Fit Might not be Perfect.
Size: Medium, Color: Blue Plaid, Size: Medium, Color: Blue Plaid
Cute, comfortable and breathes like a spring breeze! The only complaint here is the fit. Several folks mentioned it not being a loose fit, we had the opposite problem, fit the chest and shoulders perfectly, but a bit baggy in the mid section. Tucked in, it kind of muffin tops out a bit, but loose it is lovely how much this thing breathes. Overall I think we are going to try a size down, but will update once we have a better handle on that. Quality wise, this shirt is great, strong, lightweight material that I can see lasting as long any other brand.
