Hi Paul and the team at Trekitt Loving your reviews once again! This happens to be one of your longer reviews and now I know why; I’ve ordered & received mine last weekend and I was fortunate as it was the last one available from you guys and this decision was of course influenced by the team’s hard work - producing high quality reviews of high quality products. It seems that superior products like these come to us once in a while and get sold very quickly indeed! Just to help others: I’m just under 6 ft and of a slender build and the Medium is a fantastic fit. The jacket is surprisingly lightweight considering how it appears on screen and this will go well with my Rab Microlight Alpine jacket which I also bought recently. Please advise Paul, for those who run cold like myself, I find that wearing two down jackets; one over the other - especially when travelling slowly/stationary, is going to be a potentially warmer and much more flexible option rather than having a 1 jacket (heavyweight option), especially for those who are going to things like stop start trekking ie base camp treks to Everest, Annapurna circuit, K2, Mount Kilimanjaro etc. Look forward to your advise, thank you once again and all the best.

[@trekitt]

Hi Jay, thanks for your kind comments and for buying from us. You're right, multiple thinner layers are always better than one big thick layer. They are more versatile can can be warmer. Paul.

[@mark0361]

Great choice Mark, the Kyros is an absolute BELTER! Happy Christmas to you and yours. Paul.

[@Daavitt-qw3ze]

​@@trekitt hi buddy. I'm really torn between the xeros and the kyros. The extra down fill of the kyros doesn't seem so big and bulky in your reviews. I'm learning towards the kyros for sure. But this is just needed as a UK winter jacket nothing more. I'm in-between sizes in different makes also, mens med/large. I'm only 5ft10, 34w. I'm guessing the medium will more than suffice? Any help would be great. Which would you go for? Thanks in advance.

[@trekitt]

@@Daavitt-qw3ze For the UK unless you're deep in the Scottish winter scene or particularly feel the cold then the Xeros is up to task, and would still happily tackle Scottish winter fun with the right layers. Ben has a Xeros and is very happy with his for UK use. He's 6'3" with a 43" chest and 34" waist and wears a large, so a medium should work for you unless you're particularly broad in the chest/shoulders.

Great review! I recently purchased the lighter weight sister jacket to the kryos, the ME xeros jacket, which also utilizes the new firestorm construction and gore infinium drop shell outer. Haven't had a chance to use it yet but it is astonishingly warm for a medium weight belay jacket. Hoping to use it for winter alpine climbing and ski touring here in the cascade range in the United States! I think it may be suitable for light expedition use as well. If you guys at trekkitt have a chance, I'd love if you did a review of the me xeros jacket as well! Thanks for your awesome video reviews!

Christmas Eve, all my shopping Done!, why, just why Did i watch this video?.. i now realize i need this jacket!!!... it had better be Totally waterproof though!

[@DavidSmith-ql3zp]

Well, to be fair he does say that it isn’t somewhere in the vid. Also, when you unpack it, you often find that many jackets have a little card inside the pockets reminding you that the zips aren’t fully waterproof and that you need to be careful with electronic devices that might be affected by moisture.

[@trekitt]

Like David Smith says, watch the whole video and I make it clear that the Kryos isn’t 100%, guaranteed waterproof. But tbh you’d have to try very hard to get wet in it. Paul.

@@trekitt hi Paul, OK with a rucksack for multi day trekking?

[@turtle-Alchemist]

Amusing that your caption for weight has it at 86kg, made me giggle did that! It seems this may be a better choice than my current Rab resolution jacket due to it being more breathable and less bulky overall.

[@thewelshnomad7094]

Great review, what would you say would be warmer the Kryos or the citadel?

[@trekitt]

It's pretty hard to answer as they're for slightly different things. For standing around (belaying, for example), the Citadel is pretty unbeatable. For active mountaineering in ultra-cold conditions, the Kryos will be the more suitable option. I'd say outright warmth is quite similar, though.

[@andrewdennis6983]

Jesus! This has just crushed my Fjallraven Keb layering (total £853). Bamboo base layer, Keb hoody, expedition down, Keb Eco-shell. And IMO the Kryos is a very well thought out construction and use of materials. The Kryos with a Keb hoody and bamboo base layer sounds like it's job done.

[@Harrycowlton]

What altitude would you take it to? I am thinking maybe Island Peak in nepal? I have the Rab Batura jacket in Large, I am now a medium and its a but heavy to lug around for a day climb in 30days of trekking? Any comments appreciated without of course liability!

[@trekitt]

Harry, check out the Exo, which is designed for 7000m use. - www.trekitt.co.uk/clothing/jackets/mountain-equipment-mens-exo-jacket-magma__40449 It's the warmer version of the Kryos with the Firestorm Construction. Paul.

[@dosanshane]

Hi Paul, how would you compare this to the Arc firebee, appreciate there is a big price difference

[@trekitt]

Hi Shane, the Firebee is much warmer and compares better with the M.E Exos, which we’ll be filming very soon. Paul.

[@MrTurbo87lx]

How would this compare with the rab infinity jacket it terms of durability warmth and overall construction? Thanks

[@trekitt]

Durability and warmth will be pretty similar, but the construction is very different. It's quite a lot to put into a comment so I'd recommend watching the 'what is it made of' section of each video which will explain it better than I can here. Harry

Hi, im looking for a down jacket for summit days in 6000-7000 peaks (Chimborazo-Aconcagua-Mera-Lenin peak) , so i think this kind of jacket could be ideal. Willbe Kryos good choice? Im looking for something around 230-250 grams of 800fp down that van wear in cold conditions over baselayer+fleece+gore jacket to get protecction in between -10 to -20 enviroments. Maybe in some of this summits in a bad they could have -25. Also i checked Exo jacket, since for sure its better for the higher summits not sure id with kryos using under a polartec Alpha fleece, instead a normal fleece i could get almost the same protecction. What will be other option naybe from Montane? Did you Check Simon Makalu down jacket? Thanks for the help!

[@trekitt]

The M.E Exo jacket would be the logical choice. But the Kryos would also work with additional layers and be more versatile in less extreme conditions. Thanks for watching. Paul.

[@VevoV]

Hi Paul, I was searching for this jacket and they seem to be sold out everywhere, I am forced to make a decision on the Exo jacket, the problem is, breathability. Is the 30D exo going to be worse in terms of breathability? I really am looking for a jacket to withstand -20f temperatures while being active and stationary, but also warmer temperatures.. 0C, I was also looking at the rab infinity, cannot decide between these.

[@trekitt]

There's a very negligible difference in breathability, but you'll most likely find the Exo too warm for active use in the temperatures above. For static use it'll be ideal, but it warms up so quickly that you'll most likely begin to overheat when you get moving, leading you to believe it's not breathable enough. I guess it depends how active you'll be, which layers you'll have underneath and generally how warm you are as a person. Harry

[@VevoV]

@@trekitt thanks Harry, I am leaning on the exo for alaskan/himalayan weather, I would most likely only wear it below 0C is that even too warm?

[@bob-a-job]

Nicely done once again guys. Looking for a mid-weight 750-850FP down jacket durable & water resistant enough to wear as an outer(over merino or PolarTec base-layer & wicking fleece mid-layers). But be able to layer under my slightly oversized Changabang for the most gnarly damp, yet frigid temperatures on the hills & mountains. Preferably one with plenty of storage(batteries, binoculars, bottles, GPS, gloves, headlamp, map etc.) How do the materials & fit of the Kryos compare with ME’s Baltoro, Paiyu & Trango down jackets? Besides the Fill Power & Fill Weight of down used in each design, do they all utilise ME’s off-set baffle construction, heat reflective scrim, hydrophobic down treatment etc? Also be grateful for some advice on sizing. If it helps I have a 45in chest, broad muscular shoulders, 17.5in neck, 36in waist & muscular seat/thighs. Look forward to watching more of your informative content in the near future. Regards & thanks. Bob

[@trekitt]

The Kryos is in a slightly different category of jacket to the other two, with a 10D Gore-Tex Infinium outer shell it is much more weather resistant than the others, but due to the lighter weight face fabric it is going to be less durable, particularly compared to the Paiyu with it's 40D Drilite Loft outer. The Baltoro sits in the middle of the two with a 20D Drilite Loft outer. They do all use the offset baffle design, or a variation of it to help increase warmth and reduce cold spots on the jackets, the Paiyu and Baltoro use the Radiant Barrier tech for heat reflection, but the Kryos uses ME's Firestorm construction which works a little differently, but ultimately achieves a similar result. ME does not tend to use hydrophobic down treatments on their products, instead choosing to rely on water resistant face fabrics and DWR outer coatings. In real world use we haven't noticed a meaningful difference with the lack of hydrophobic treatment (Ben has a Xeros jacket which he absolutely loves and has put through it's paces in some questionable weather). When it comes to fit, you would be looking at an XL across the board, but would find the Baltoro to be slimmer in fit compared to the other two and may struggle a little with layering underneath. The other two will be a little more generous in their fits to make for easier layering. Hope this helps and you continue to enjoy your outdoor adventures!

[@bob-a-job]

Thanks very much for the prompt & detailed reply. So would you say the Paiyu & Trango jackets aren’t so much designed for layering underneath a Hardshell? Think that ME’s Lightline has more Fill Weight of 700 Fill Power down in it than the Baltoro, Paiyu & Trango jackets do(?) Also looks more suited to wearring as an insulated mid-layer. Would you say the Lightline is as warm or warmer than the other jackets previously mentioned? Keep up the great work. Much obliged. Bob

[@trekitt]

The Paiyu is going to be more suited to being the outer layer that gets thrown over everything else, similar to the Kryos, the Baltoro will be easier to get under a shell, but will work equally as well as your outer layer as long as it's not horrific weather. The Lightline is similar in warmth to the Paiyu, but is a more casual fit. It's a slightly more every-day version of the Paiyu, still very capable on the hill, but won't pack quite as small and has a less alpine oriented fit. @@bob-a-job

[@sankalpsingh5619]

Can it be compared with rab infinity jacket If yes then how ,how it is different from infinity jacket

[@trekitt]

Hi, I suppose you could compare the Kryos with the Infinity on paper, but in reality the Kryos is a far more serious proposition and has that amazing Firestorm Construction to increase warmth without adding weight. I've worn both, and I'd be more confident in the mountains wearing the Kryos. Paul.

[@carillion09]

I'll be back packing Hadrians wall in March, Would this be better than an arcteryx Beta lt of something similar?

[@trekitt]

The Beta LT is a hardshell whereas this is an insulated jacket, so the two aren't really comparable. I would give our Customer Service team a ring if you're unsure about which insulated jacket to choose - we stock a lot and it can be daunting! Harry

Very noisy jacket, guess thats the gore-tex. Is it as noisy as it sounds or is the mic adding to the volume? I have a montane duality with 60g primaloft gold insulation, which is good but a little noisy too.

Sadly, GoreTex fabrics are always noisy. I have an Arc’teryx Firebee with Infinium shell and it’s noisy as heck.

[@trekitt]

I wouldn't say "very noisy" but there is certainly some rustling from the fabric. That's the nature of that tough and weather resistant fabric. You can't have it all! Paul.

I have that jacket and I do not agree to the initial post. There must be a distance between the skin and the outside. Only then there can be trapped air and insulation. You can get the Xeros, it is less bulky and less warm.
