Product Description
Engineered to be the lightest, warmest synthetic bag on the market, the Mountain Hardwear HyperLamina features Thermal Q 60-gram Thermic Micro insulation inside an ultralight 22d Dobby shell. The insulation is thermally mapped to concentrate warmth around your core and feet, and thanks to the company’s proprietary Lamina construction, welded to the shell and lining to eliminate the cold spots caused by traditional stitching Read More
I'm still not getting it. This one and the Kelty Sine 20 bag have same rating. This one is synthetic, and the kelty one uses 800fps down. Yet they have almost the same weight. What am I missing?
YuanYuAre you just curious why they weight the same but are using different materials? That last part is the answer. Kelty is using a heavier fabric and more of it, plus extra weight in features, while MH is using a much lighter fabric with a pretty slim/tight cut and a minimalist design in these bags. The lower weight of all that combined offsets the higher weight of the synthetic insulation and the bulk is comparable. I think MH is a tad generous in their temperature ratings where Kelty has usually been closer to accurate, but I don't know about those new Sine bags (they don't look particularly lofty like a great 20F bag but that could just be the photos or a bag that wasn't allowed to fully loft before the session). The Hyperlamina bags have been one of the best choices for synthetics for awhile now. It's a nice insulation compared to most. The new stuff from Marmot this year is worth a look too.
Is this bag decently compressable? I ask because I really enjoy going on long, aggressive bike touring missions and my old bags are really, really fucking bulky seeing as they come directly from the year 1982 and are my dad's.
I carried a spark for my AT thru hike, and I must say it served me well, one of my favorite pieces of gear, I have to say though, because I started in February, snow was common place thru Georgia North Carolina and Tennessee, I had to also carry a silk liner and wool longs to keep warm on the coldest of nights, but overall very comfortable and "cape mode" with the half zip was awesome around the fire
Jacobus I thought I was seeing things too. $67.50 to Canada is wild. Are the customs charges included in that, I wonder? I really hope massdrop opens a Canadian branch for the site to help mitigate some of these inherently expensive shipping costs for some of their items.
gnarledcouleeNo that's just what MD charges me to buy!!!!
All other costs are on top of this and the b... charge me often $ 10 to collect $5- $10 in taxes!!!!
They seem good, although for a synthetic bag I much prefer a snugpak, I've yet to see a synthetic that hits their balance between warmth, pack size and most importantly life time as long as you care for the bag they last a VERY long time compared to a lot of other bags I've had.
YuanYuSynthetic is less expensive to down 99% of the time Because down is a superior insulation. As far as synthetic being lighter, it depends on the down, EN rating, etc. Typically high fill power down is more compressible and has a higher warmth to weight relation than synthetic. the biggest benefits to synthetic are that it's cheaper, dries when wet and hypoallergenic.
