The Rheem Commercial Universal Gas Water Heaters are expertly crafted to seamlessly integrate into compact retrofit scenarios while delivering the robust performance necessary for heavy-duty applications. Specifically designed for commercial use, the Universal 100 Gal. 199,900 BTU Natural Gas Water Heater boasts a rapid spark-to-pilot electrical ignition system, ensuring swift activation of the gas-powered burner. Featuring a capacious 100 Gal. tank and versatile water connections, this heater accommodates a diverse array of hot water demands. Its compact footprint, minimal vent height, and multiple water connections make it an optimal choice for replacement installations. It's imperative to note that this model necessitates a 120-Volt power source. Notably, for residents in California, Utah (Effective 7/1/18), and Texas, regulatory requirements regarding emissions standards must be adhered to, as outlined. Key highlights include its space-saving design, system sentinel LED diagnostic system, durable tank construction, stainless steel burners for enhanced performance, and a low-profile automatic flue damper. Moreover, servicing is simplified with features like a factory-installed full port brass drain valve and hand-hole cleanout. The direct spark to pilot ignition system ensures energy efficiency, activating only when heat is required. Additionally, built-in corrosion resistance and insulation contribute to prolonged tank life and energy savings. The gas control system offers precise temperature adjustment, ranging from 100°F to 180°F, ensuring optimal performance. For tailored configurations, Rheem's universal line offers water heaters ranging from 35 Gal. to 100 Gal. models, available in natural gas and liquid propane variants, catering to varying BTU/h requirements.

Comfortable, Practical Everyday Cotton Shorts That Hit Most of the Right Notes
Size: Large, Color: 2 Pack - Navy
These Fruit of the Loom Eversoft cotton shorts are exactly the kind of go-to casual shorts you reach for when comfort matters more than fashion. They’re soft, simple, and dependable — great for lounging around the house, running errands, or just staying comfortable on warm days. The Eversoft cotton lives up to its name. The fabric feels genuinely soft against the skin and stays comfortable even after hours of wear. It’s not clingy or rough, and it breathes well enough to keep you cool on a hot afternoon. For everyday comfort, they’re noticeably better than basic cotton shorts that can feel stiff or scratchy. One of the features that makes these a practical choice is the pockets. They’re real pockets — roomy enough to hold your phone, wallet, keys, or whatever you carry on a quick outing. That’s worth calling out because a lot of lounge shorts feel great but skimp on usable storage. These don’t. The fit is relaxed without being sloppy. The elastic waistband with drawstring adjusts easily and stays comfortable through activity or inactivity. They don’t dig in or feel restrictive, which makes them easy to wear for sleeping, working from home, watching TV, or walking the dog. Build quality is solid for the price point. The stitching holds up through wear and washes, and the shorts don’t lose shape or shrink dramatically after laundering. They’re not going to feel like premium athletic gear or performance fabrics, but for what they are — casual cotton shorts — they stay reliable over time. These aren’t going to be your choice for intense workouts, formal occasions, or anything that demands technical fabrics, but for everyday comfort and simplicity, they’re hard to beat. Soft, breathable cotton with pockets and a dependable fit makes these shorts versatile and easy to wear on repeat. Overall, these Fruit of the Loom Eversoft shorts are exactly what most people want from casual summertime wear: comfortable, practical, and dependable. Five stars for everyday use and solid comfort.

Comfortable Everyday Cotton Shorts
Size: XX-Large, Color: 2 Pack - Black
Soft fabric, good stretch, and a relaxed fit that lands at a perfect length, these shorts hit that sweet spot between lounge wear and quick‑errand gear. The waistband has enough give without feeling flimsy, the pockets are actually usable, and the overall feel stays comfortable through the day. For the price, they’re an easy pickup that delivers exactly what you want from simple cotton shorts.

Good for the price
Size: X-Large, Color: 2 Pack - Black
they're very good for the price. There's definitely alot of noticeable cost cutting (material feels kind of thin, and the inside of the shorts look "rough" and unfinished). But still they look good and are comfortable and light. Great for summer and will live up to their price. fits well.

They are comfortable!
Size: X-Large, Color: 2 Pack - Navy
I really like them. Pockets are very helpful and the size was right for me eventhough it was suggested a size bigger. Washed both already and noticed no shrinkage. Very comfortable and the length is just above the knees. Great for hanging about, in the gym or even a trip to the store.

BIG GIRLS LOVE 'EM TOO!
Size: 3X-Large, Color: 2 Pack - Black
I am a plus size gal. I was looking for some sleep shorts, but all the ones for us plus size gals were so short I may as well not have been wearing anything. I decided to look in men's shorts, and found these. They are nice and long, and the material is nice and soft. Also, unlike the women's shorts, the pockets in these are nice sized, big enough for my phone and then some. There's a drawstring, but the elastic in these is plenty to keep them up and riding at my waist, where they're supposed to be, without having to tie them. Typically I wear a 2X, but I purchased these in a 3X because I like a little more room in my PJ bottoms, and they fit great. The only thing I don't care for necessarily is that the elastic waistband is just a smidge scratchy, but after wearing them a while I found it didn't bother me. And the price is pretty good for two pairs - much cheaper than women's plus shorts. I liked them enough that I came back and bought 4 more pair!
