Several weeks ago I was contacted by Mary at Shiverswear and was asked if I’d like to review some of their long lightweight underwear. At first I was a little skeptical because long underwear wasn’t something I saw a cyclist being able to use. After looking at their website and seeing some of the applications I agreed and she shipped me three pairs.
Detailed Product Information on Shiverswear
Shivers are made of 5% Polyester (mostly in the sock and hip area to due its wear qualities), 10% spandex for elastic qualities, and 85% Nylon for strength and comfort. They’re cold-weather tested to keep you warm between 15F and 50F(-9.4C and 10C). Their unique design incorporates an attached sock that helps isolate your lower body from the waist to the feet from the cold. They also use a unique knitting process with special fibers that will keep you warm while out in the cold but will not cause you to sweat if you go indoors because your body is able to “breathe”. Shivers are 100% Made in the USA in Asheboro, North Carolina.

Shiverswear Lightweight Long Underwear Review
My Shivers arrived in the mail and contained one pair of XL blue and one pair of XXL black (I also received an additional pair of XL black a couple of weeks later). When opening an individual package of underwear I was surprised at how lightweight they really were compared to my normal cycling tights. The Polyester reinforced areas were easy to identify and the attached socks looked interesting. Putting them on the first time I took it pretty slow because I just wasn’t sure how sturdy they were and didn’t want to tear them. My concerns were unwarranted though and they went on just fine. They felt good against the skin and were comfortable.
At this point I want to talk about sizing. I’ve made no bones about it on Biking To Live that I’m trying to lose weight. Because of that I can’t buy any clothing product that will fit my girth without it being too big in another area. Me having a very short inseam doesn’t help either because the area that usually suffers is length. Shivers were no different. They are designed for height-weight-proportionate people in mind so if you’re big like I am you’ll end up having to deal with the extra length.
Shivers on the Road Bike
The weather here in Dallas didn’t cooperate too good and it was a couple weeks before I could get a ride in outside while wearing Shivers. When I did the first outing was for about 18 miles in 45F-50F temps and no wind. I wore the XL Blue pair under a pair of bibs and could immediately tell on the road that they felt great. They kept the cold at bay and kept my legs warm. I really liked the attached socks. They’re probably too thin by themselves so I wore cycling socks over them and that double layer kept my feet and toes very comfortable. This first ride wasn’t without an issue though. After about 10 miles I started to experience a hot spot on my inner right thigh. It wasn’t too painful but noticeable. I thought this could be due to a couple of things: the XL were pretty tight in my waste/hips area so they could be binding, the seams in the crotch of the Shivers could be irritating me, or it could have been my bibs. I would mix things up a little in Ride 2 to see if I could pinpoint the problem.
Because of the hot spot I experienced in Ride 1, I opted to wear the same Shivers (XL Blue) (after being washed and hung to dry) but with another brand of bibs. The change in bibs seemed to help a little but I was definitely experiencing some movement restrictions in my thighs/hips due to the size of the Shivers. It wasn’t bad but noticeable. Ride 2 was again, between 45F-50F for 18 miles but noticeably windier than Ride 1. With that extra wind I did notice a little more ‘coolness’ on my legs but it wasn’t too bad.
After having tried the XL Blue for two rides I opted to go with the XXL Black for Ride 3. Temperatures were again 45F-50F and the wind was blowing between 5-15 mph. This ride actually felt more like a late fall ride than an early spring ride. I noticed immediate improvement while wearing the XXL Shivers. I had zero movement problems and experienced no hot spots over the next 18 miles. They kept me nice and warm throughout the ride.
Overall Impression of Shiverswear Lightweight Long Underwear
I believe Shiverswear has a great product in Shivers. While cycling in long underwear may not sound appealing (it didn’t to me) it may be due to the word ‘underwear’. I would actually consider Shivers to be a lightweight sport tight but I can understand the underwear name due to their design (reinforced areas and a fly). They performed as advertised, and even though I had some fit issues initially, I enjoyed a great ride after I got that ironed out. I liked the attached sock so much that before starting out on all three rides I actually forgot to pull cycling socks out to wear and didn’t remember until I started to put my shoes on. I think Shivers would be a great, low-cost investment to add to your cycling closet for use on those early fall or spring rides.
What was good about Shiverswear Lightweight Long Underwear:
- The attached sock added extra warmth to the feet/toes.
- Lightweight enough to feel good on the skin but also provide warmth on a chilly morning ride.
- Low-cost compared to cycling specific tights you’ll find on the market.
- Multiple colors make it easy to blend with your shorts and bibs.
- Made in the USA.
What you may not like:
- Sizing may be a problem for heavier cyclists.
- If the wind is really kicking it you might experience some blow through.
- They’re not designed to get wet so if it’s raining a waterproof pant or tight would be in order.
