Product Description

The Men's Stone Glacier Helio Bottoms are a key part of any layering system. These hunting long johns are designed to sit above the top of your boots to prevent the fabric from bunching up and causing discomfort. An elastic trim waistband on these Stone Glacier bottoms ensures a secure, comfortable fit, while Polygiene® odor control technology neutralizes your scent to prevent detection by game animals. A side zipper allows for quick temperature control, enabling you to vent your lower half if you get hot. An essential piece for every backcountry hunt, the Stone Glacier Helio Bottoms offer comfortable cold-weather protection.

  • Elastic trim waistband with stretch

  • Polygiene® odor control technology neutralizes body odor

Great base layer
Side rippers are great. Hiked a bunch the other day, got warm and unzipped them and cooled off instantly.

Great layering system
I bought these to use under my De Havilland Pants (which are absolutely 5-stars!!) because I loved the idea of the coordinated zippered vents. We went out recently to fill an end of October Raspberry Island (Kodiak) elk tag and I had a chance to put the system to use. I found that opening the vents on the De Havilland Pants was generally enough to cool me off, but I did use the zippered side vents on the Helio Bottom once and found that with the vents being so long, when you open up them it feels like you just changed into a pair of shorts (or took off your pants altogether), which is pretty fantastic! The fleece material is really smooth and fitted, so it doesn't bunch up or feel bulky under your outer layers. I was worried that the zippers would feel cool or uncomfortable against my bare skin, but that wasn't the case. The zippers felt cold momentarily when they first went on, but warmed up and I didn't even notice them after that, so not an issue at all and I wore them for at least 12-hr days. The Helio Bottoms were warm, durable, and whatever Polygiene is, IT REALLY WORKS. I may be a woman, but after climbing several thousand feet multiple days hunting, I'm pretty sure I did not smell like a rose, but you wouldn't know it from these bottoms! I wore them multiple days and I swear they still didn't smell bad, or like anything at all really. By the time I got home, I washed them because they were visibly dirty, but they did not smell bad. The only reason I gave the Helio Bottom 4 stars rather than 5 is that the waistband is uncomfortable and not particularly stretchy . It's a thick heavy-duty elastic band and I found that it just became uncomfortable after a few hours. I felt like it cut into my waist after sitting and glassing for a while. I'd say this is a great product overall and goes perfect under the De Havilland Pant.

Excellent quality and service!
Like all my SG gear, the quality of the Helio line is second to none and the customer service from SG is always outstanding. The pants are comfortable and very well made Looking forward to wearing them on my late season deer and elk hunts.

Great fit and function!
My helio bottoms are great. The side zips keep me cool while climbing and I can close them up once I stop to stay warm. Great base layer insulation under an outer layer!

hey guys ! Just got back from the Yukon on Dall Sheep hunt. It spanned 8 days and we covered over 100km most days with full packs. The backpack sky5900 was unbelievable. I have had it for 4 seasons now, and we really pushed the equipment and ourselves to the limit. I was so impressed with how it handled weight and how it allowed me to carry heavy loads far distances. The guide was running the guide 7900 and I noticed the same thing. Excellent backpack. Clothing , helio bottoms were awsome for the tent and to warm up with. Dehavilad Pant was an awsome hiking pant, no rips or tears pockets functioned well Full leg double zipper on sides was awsome. Guide was laughing at me becuase there was no mesh behind the zippers was never a problem except for bugs.. Sleeping bag , chilkoot15 Was warm, packed nicely,. Would recommend having shorter and more panels for the down because the down moves to one end pretty easily. Struggled a bit with the sleeping bag "rolling with me" Spent alot of time rearranging the bag if I moved at all. Skyscraper 2p tent. Has been good for me for 3 seasons hunting but had always been good weather. This trip to the Yukon we encountered alot of wind. Somtimes gusts over 30kn The tent struggled mightily in the wind, straps were ripping, the tent was always caving in the poles bent from tightening and tying things down, The stabilizer arm was trying to help but didn't do much. The tent was caving in on us luckily we had hiking poles to help the poles be more sturdy but the guides kuiu wasn't even flinching...ours was buckling and trying to tear it self apart. The plastic clips and hooks never stayed secured either. I had been warned about that tent in winds and I guess they were right. So I'm not mad I definitely got my moneys worth out of the tent, its just if there was more rain than what we had. We would have been completely soaked and frozen... i personally will not buy this tent again because if you got in bad weather this tent cannot function as a 4 season shelter its barely 3 season shelter...nice weather only basically...its super light and nice to pack but I have to get something safer. I wont recommend this tent, but I respect you guys a lot and I'm not on forums or groups blabbing about it... i just wanted to let you guys know my experience with it incase you guys wanted the honest stories I look forward to trying the upcoming products like the bino harness and gators. Thanks very much. And thanks for the great backpack. It definitely helped make the hunts safe and successful.
