Fuck lyft. Keep more of that money for yourself.

I spent 2 years riding my bike year round in upstate NY. Unless it’s one of those skinny tire road bikes, even a shoddy $100 hybrid or mountain bike from Walmart can ride in the snow reasonably well. A road bike can work as long as plowing is done.

The only time it’s not really possible is right after a major blizzard depositing a foot+ overnight.

thermals can be bought for a single lyft ride.

Getting a waterproof outer layer is key, but to do that cheaply you need to check thrift stores. Waterproofing is more important than warmth, if you get it a little loose you can fit an extra layer, like a sweater, inside for warmth.

Snow goggles are useful when it’s actually snowing, but sunglasses work in a pinch. You get them for around $15 new, which again, is paid for in 1-2 lyft rides.

So if we assume like $40 for the outer layer, it’s roughly $65 for the basics of winter biking gear. If you’re living somewhere with winter I’m already assuming you have gloves, a hat, and a scarf, but you can get all three for anywhere from 15-25 bucks.

$80 is like 8 lyft rides at minimum charge levels. Commuting both ways from work, that’s less than a week. One month of lyft 5 days a week in both directions is like $400.

u/ShinyTile · 2 pointsr/running

I'm actually making a video about this today and tomorrow, I'll send you a link!

A little protip that I do if you're trying to save some $$$. If you don't want to drop $80 or whatever on dedicated running tights, you can pick up long thermal underwear broadly like these. Since a lot of these fabrics aren't as technical as dedicated running tights, you may find they won't wick sweat as well, but I don't find my legs get too sweaty in the winter anyway. If you're worried about chafing, you can either get long athletic boxer briefs or (for maximum money saving) wear your existing running shorts (that have a liner) underneath the long johns.

Again, that's a pretty cheap method since you talked about the prices being higher than you thought.

If you're willing to drop some $$$ on a jacket, I'm a big fan of this jacket by TNF. Great for me into the mid 20s with a base layer.

For a hat, check out Smartwool or grab a buff for more versatility.

You'll find a lot of people suggest running in layers, and it's true you shouldn't be in a tshirt plus one heavy jacket, but I think it's more important to dial in your 'system' and focus less on layers. You don't want to need to have to strip (and carry) layers on a training run. Your system should work from door to door.

https://www.amazon.com/MERIWOOL-Merino-Midweight-Baselayer-Bottom/dp/B01MZWP936/

I like 250g vs something heavier like 400g because I can double up when it's cold or go single layer when it's less cold. And when I'm single layer I have a spare set if I roll my neck seal. Also get wool socks. The costco ones are good or some on amazon. Just be careful as the amazon search results for wool socks have a lot of socks that are like 50% wool but the good ones are like 90+% wool with just a little rayon for stretching. Single socks is ok, double socks is amazing.

u/docb30tn · 1 pointr/AskMen

I have a set of Polartec base layer. I couldn't find it b/c I got them in 2004. It's similar to this. It's not tight like leggings, but somewhat looser. As a base layer by itself, with shorts and a tshirt it won't provide adequate warmth in lower temps (think 20 degrees and lower. With other clothing on top like midweight clothing it's great. UA is good, but there are other brands that do just as well and are just as durable.
The male leggings are pretty good. I wouldn't wear them under shorts though. I'd wear a midweight pant if it was that cold.

u/WittensMittens · 1 pointr/malefashionadvice

I'm looking for something that should be easy too find, but for some reason I can't.

this is basically what I want But I just want the top. All I can find for long john type shirts is henley style and I want a full button down. Thought it would be super easy to find at walmart but nope. It's the kind of shirt that I always see in westerns and shit.

Please help!

Rain pants are OK, but for many days where it's not very cold but quite wet, one can get really uncomfortable and sweaty underneath them. They also get stuck in my chain sometimes, and are baggy and annoying to take on and off.

I've switched away from rain pants and wear some cheap long johns [https://www.amazon.com/Duofold-Weight-Wicking-Thermal-Medium/dp/B006SRTGC2/ref=sr_1_1?s=apparel&ie=UTF8&qid=1487982787&sr=1-1&nodeID=1040658] under some loose but stretchy synthetic shorts. I pack my pants in my bag and change when I get there. I also leave a pair of nicer shoes at work and usually wear my cycling cleats. I leave everything sitting out (not just wadded up in a bag) all day and they are typically completely dry by the time I head home. I've found this arrangement to be much more comfortable than rain pants.

When the weather's nicer I just ride in on my jeans I wear at work. When it's dry and cold I wear the long johns under whatever pants I wear in. As far as my upper body goes, I've found that an undershirt and multiple layers really help keep me warm when it's very cold out.

Gloves are also important. I wear a pair of glove liners under cotton gloves. They both dry out pretty quickly at work.

u/poilsoup2 · 1 pointr/snowboarding

pack layers and you can shed as needed: heres my layout

Base Layer:

I try to avoid cotton stuff cause of chafing, highly recommend exofficio if thats an issue.

runner leggings/thermal leggings

long sleeve work out material shirt/ thermal shirt

smartwool socks! smartwool is the best. I use it for backpacking too.

Second Layer:

arctix snow bibs from amazon : 40 (You want snow pants/bibs. getting snow all down your pants/up your back is awful.)

A flannel or other heavy shirt type

Third:

I have wantando jacket (70 from amazon) reeeealy warm. Hardly have worn it out and its been like 10-15 on the mountain. Id imagine I could wear it down to zero.

A lighter waterproof jacket incase the heavy jacket is too much.

Gloves: Get some nice waterproof insulated gloves and glove liners.

If you got all of those youd be fine an any resort park

u/ThePretzelRuns · 2 pointsr/uofmn

I agree with most of this information, but for all of the people from warm climates that will see this, the winters are absolutely manageable, and the way this person wrote the winter segment almost seems like a joke. Suggesting a windbreaker over a thick winter jacket? Perhaps just bad wording, but bad advice. Over-the-ear headphones as protective winter gear? You've got to be kidding.

But yes, if you don't dress for the weather, it's gonna suck. Coming from someone who grew up in upper midwest winters and comfortably biked through the winter for all four years at the U, here's what I think you should get to be comfortable:

  • A solid over-ear winter hat
  • 1-2 beanie winter hats (should cover your ears, good for layering, and you'll lose one)
  • An absolutely reliable, wind-blocking scarf, cold weather mask, or other face covering
  • Waterproof/windproof winter jacket (hood recommended)
  • A nice mid-layer (like a sweatshirt or fleece)
  • Long underwear/base layers (under armour, thermal leggings, etc)
  • Skiing gloves (waterproof/windproof-- get two pairs because you'll lose one)
  • Liner gloves (could be the crappy $2 ones from Target, but it doesn't hurt to spend a bit more)
  • Wool socks (multiple pairs-- they're comfy and functional)
  • Waterproof snowboots

    It's not hard to thrift for many of these items to get them cheap. Hit the thrift store before October to get your best selection-- heck, go this weekend!

    ​

    Also, after being directly connected with more students than I can count from classes and extracurriculars, I didn't know anyone who preferred using the Gopher Way. I wouldn't count on using it unless you want to add 10-30 minutes through isolated tunnels to your commute. It's far easier to reliably bundle up and walk straight to wherever you're going, as long as you can navigate the often-plowed snow (wheelchairs, crutches, and other mobility obstacles might be an exception).
u/johndesmarais · 8 pointsr/DCcomics

Not in the least. Superman's costume is one of the strongest bits of iconic imagery in American popular cultural in large part because it's major features have remained relatively unchanged over the years. It's a strong, recognizable, brand - and there's a lot of value in that.

(Also, to me, not having that red visual break in the middle makes his costume look like thermals - https://www.amazon.com/Mens-Long-Thermal-Underwear-Large/dp/B016CEGRHW).

u/1800butts · 1 pointr/tall

I have the same problem! Amazon helped a lot. They have lots of colors/sizes/cuts of union suits and long underwear. I love this one, but here are a couple more - hooded & zip up - to get you started. If you search "union suit" or "one piece long underwear" on Amazon, you'll find tons of options. Hope that helps!

u/JustinDoesTriathlon · 2 pointsr/C25K

Couple things:

Underarmor "heatgear" is for wearing in the heat, not the cold. Their Coldgear stuff is for the cold.

That red and black suit looks... super sketch, ha. Something like this would work for tights under running shorts, and then wear some poly underwear beneath them. For up top, a long sleeve poly top will be good; doubt you'll need a coat.

You'll feel cold when you walk outside, but once you get going it should balance out. You don't want to be warm when you walk outside. If you're interested in more, I did a whole video on winter running gear which dives deeper.

u/AxisOfAwesome · 10 pointsr/Frugal

the Union Suit. I absolutely love mine in the winter.

Added bonus - wearing a tight one-piece under your regular clothes makes you feel like a superhero.

u/procrastinationrs · 2 pointsr/tall

I haven't turned up definitive information, but based on other types of "causal" pant, Croft & Barrow's "L Tall" and "XL Tall" sizing seems to be about right. See the comments on these, for example: https://www.kohls.com/product/prd-1236378/croft-barrow-solid-jersey-knit-lounge-pants-big-tall.jsp

Assuming the company uses the same sizing across products, these long underwear should be a good length: https://www.amazon.com/Croft-Barrow-Solid-Thermal-Underwear/dp/B01MG2HHCD?th=1&psc=1

u/Questionable_Tires · 5 pointsr/jobs

So, I'll try to hit each of your points.

As far as organization goes, I typically tried to line up the boxes near the front side cooler where they are stored. It minimizes distance you have to move to stock the shelves.

As your work into the shift, you'll get used to the schedule. Make sure you maintain your schedule though. Try to get to bed at the same time every night and wake up at roughly the same time.

Cheap thermal underwear are great. Like https://www.amazon.com/Duofold-Mens-Mid-Weight-Wicking-Thermal/dp/B006SRT02I/ref=zg_bs_5888822011_2?_encoding=UTF8&refRID=X500F5WM0BX6DTVG2CBD# they make tops too.

Go for healthy drinks, I usually went with just water, or some matcha green tea.

Stretch stretch stretch, before during and after. For really bad aches, I go with bio freeze. The most important thing however is proper lifting. Lift with your legs, keep loads close to the body. Don't twist with the load, move your feet.

Condense when possible, reorganize your stacks to float the empty ones to the top.

Pay debts first

u/CharlesP2009 · 1 pointr/Hypothyroidism

2015 and 2016 were rough for me during winter since I hadn't been diagnosed yet. I spend a considerable amount of time outside at work. And I didn't want to crank the heat in my home and toast friends/family so here's what I used to cope:

I got a nice warm down comforter for my bed.

A heated throw blanket to use around the house.

Zippo hand warmer for times outside.

And thermal under garments. Top. Bottom.

I've also had a Presto heat dish for a number of years. I think I paid $60 at Costco but the going rate seems to be double that now. It's nice because it directs the heat at you rather than warming an entire room.

u/PurpleMan · 1 pointr/Outlier

I've got a set of these and they're great. Lined with a thin layer of fleece, super cozy. I wear them to football games in frigid northeastern winters and they keep me very toasty.

u/gonegone8 · 1 pointr/Ultralight

Thanks for sharing. I'm interested in a hooded merino longsleeve, such as this one. But it doesn't state a UPF rating and there isn't much selection.

u/BMXTKD · 3 pointsr/minnesota

My below zero setup is this.

Top:

Ski goggles

Neoprene mask

Jeep cap

Ice fishing jacket

Base layer long underwear

Regular t-shirt

Wool gloves

Ski gloves to put over your wool gloves

Bottom

Base layer pants

Regular pants

Snowpants

Cotton socks

Wool socks over the cotton socks

I tend to wear high top gym shoes that are about a size too big, enough room so I could fit my socks and feet into the shoes, and plus, it helps keep the snow out of your feet. Also good for driving, since it's impossible to drive while you're wearing boots.

Duofold makes very similar gear to Under Armor for a lot cheaper. These are usually what I wear as a base layer. For me, these are good for temps in the 20's- 30's F. When it dips down into the teens or single digits I throw a Smartwool shirt and a pair of jogging pants on over the top

https://www.amazon.com/Duofold-Weight-Wicking-Thermal-Medium/dp/B006SRTEZ6/ref=sr_1_fkmr0_2?ie=UTF8&qid=1481984151&sr=8-2-fkmr0&keywords=duofold+thermal+running

They also make them in heavy weight, but that would be overkill for the temps here.
