For economy rugs, check out Saxon rugs - we have the full-neck heavyweight turnouts (great for minus 20!) the heavyweight turnouts with detachable necks, the lightweight turnouts and the stable rugs.
Only down side is the Saxon stable rugs are a little 'short in depth' for cobby (or fat!) horses and don't come down the horse's sides as much as other rugs.
Saying that, the turnouts and stable rugs have had 4 years use, with no damage at all, except where a nasty horse ripped the side of my cob's turnout! Nothing that a needle and thread wouldn't fix!
The Saxon lightweight turnouts IMHO, are fantastic, great value for money, not the best fit around the neck initially, - they took a bit of fiddling with to make the fit right for each horse.
Also, I have a few Rhinegold lightweight turnouts, these too are brilliant value for money, and have survived 4 years without needing a single bit of repair anywhere! Not even a tiny rip or anything - and it's not like our horses aren't destructive!! And the Rhinegolds, unlike other 'cheaper' rugs, are waterproof - Ours haven't leaked, anyway. Highly recommended!
